This attribute is disabled by default. + + \value WA_NoSystemBackground Indicates that the widget has no background, + i.e. when the widget receives paint events, the background is not + automatically repainted. \note Unlike WA_OpaquePaintEvent, newly exposed + areas are \bold never filled with the background (e.g., after showing a + window for the first time the user can see "through" it until the + application processes the paint events). This flag is set or cleared by the + widget's author. + + \value WA_OpaquePaintEvent Indicates that the widget paints all its pixels + when it receives a paint event. Thus, it is not required for operations + like updating, resizing, scrolling and focus changes to erase the widget + before generating paint events. The use of WA_OpaquePaintEvent provides a + small optimization by helping to reduce flicker on systems that do not + support double buffering and avoiding computational cycles necessary to + erase the background prior to painting. \note Unlike + WA_NoSystemBackground, WA_OpaquePaintEvent makes an effort to avoid + transparent window backgrounds. This flag is set or cleared by the widget's + author. + + \value WA_OutsideWSRange Indicates that the widget is outside + the valid range of the window system's coordinate system. A widget + outside the valid range cannot be mapped on screen. This is + set/cleared by the Qt kernel. + + \value WA_PaintOnScreen Indicates that the widget wants to draw directly + onto the screen. Widgets with this attribute set do not participate in + composition management, i.e. they cannot be semi-transparent or shine + through semi-transparent overlapping widgets. \note This flag is only + supported on X11 and it disables double buffering. On Qt for Embedded + Linux, the flag only works when set on a top-level widget and it relies on + support from the active screen driver. This flag is set or cleared by the + widget's author. To render outside of Qt's paint system, e.g., if you + require native painting primitives, you need to reimplement + QWidget::paintEngine() to return 0 and set this flag. + + \value WA_PaintOutsidePaintEvent Makes it possible to use QPainter to + paint on the widget outside \l{QWidget::paintEvent()}{paintEvent()}. This + flag is not supported on Windows, Mac OS X or Embedded Linux. We recommend + that you use it only when porting Qt 3 code to Qt 4. + + \value WA_PaintUnclipped Makes all painters operating on this widget + unclipped. Children of this widget or other widgets in front of it do not + clip the area the painter can paint on. This flag is only supported for + widgets with the WA_PaintOnScreen flag set. The preferred way to do this in + a cross platform way is to create a transparent widget that lies in front + of the other widgets. + + \value WA_PendingMoveEvent Indicates that a move event is pending, e.g., + when a hidden widget was moved. This flag is set or cleared by the Qt + kernel. + + \value WA_PendingResizeEvent Indicates that a resize event is pending, + e.g., when a hidden widget was resized. This flag is set or cleared by the + Qt kernel. + + \value WA_QuitOnClose Makes Qt quit the application when the last widget + with the attribute set has accepted closeEvent(). This behavior can be + modified with the QApplication::quitOnLastWindowClosed property. By default + this attribute is set for all widgets of type Qt::Window. + + \value WA_Resized Indicates that the widget has an explicit size. This flag + is set or cleared by QWidget::resize() and QWidget::setGeometry(). + + \value WA_RightToLeft Indicates that the layout direction for the widget + is right to left. + + \value WA_SetCursor Indicates that the widget has a cursor of its own. This + flag is set or cleared by QWidget::setCursor() and QWidget::unsetCursor(). + + \value WA_SetFont Indicates that the widget has a font of its own. This + flag is set or cleared by QWidget::setFont(). + + \value WA_SetPalette Indicates that the widget has a palette of its own. + This flag is set or cleared by QWidget::setPalette(). + + \value WA_SetStyle Indicates that the widget has a style of its own. This + flag is set or cleared by QWidget::setStyle(). + + \value WA_ShowModal \e{This attribute has been deprecated.} Use + QWidget::windowModality instead. + + \value WA_StaticContents Indicates that the widget contents are north-west + aligned and static. On resize, such a widget will receive paint events only + for parts of itself that are newly visible. This flag is set or cleared by + the widget's author. + + \value WA_StyleSheet Indicates that the widget is styled using a + \l{Qt Style Sheets}{style sheet}. + + \value WA_TranslucentBackground Indicates that the widget should have a + translucent background, i.e., any non-opaque regions of the widgets will be + translucent because the widget will have an alpha channel. Setting this + flag causes WA_NoSystemBackground to be set. On Windows the + widget also needs the Qt::FramelessWindowHint window flag to be set. + This flag is set or cleared by the widget's author. + + \value WA_UnderMouse Indicates that the widget is under the mouse cursor. + The value is not updated correctly during drag and drop operations. There + is also a getter function, QWidget::underMouse(). This flag is set or + cleared by the Qt kernel. + + \value WA_UpdatesDisabled Indicates that updates are blocked (including the + system background). This flag is set or cleared by the Qt kernel. + \warning This flag must \e never be set or cleared by the widget's author. + + \value WA_WindowModified Indicates that the window is marked as modified. + On some platforms this flag will do nothing, on others (including Mac OS X + and Windows) the window will take a modified appearance. This flag is set + or cleared by QWidget::setWindowModified(). + + \value WA_WindowPropagation Makes a toplevel window inherit font and + palette from its parent. + + \value WA_MacAlwaysShowToolWindow On Mac OS X, show the tool window even + when the application is not active. By default, all tool windows are + hidden when the application is inactive. + + \value WA_SetLocale Indicates the locale should be taken into consideration + in the widget. + + \value WA_StyledBackground Indicates the widget should be drawn using a + styled background. + + \value WA_ShowWithoutActivating Show the widget without making it active. + + \value WA_NativeWindow Indicates that a native window is created for the + widget. Enabling this flag will also force a native window for the widget's + ancestors unless Qt::WA_DontCreateNativeAncestors is set. + + \value WA_DontCreateNativeAncestors Indicates that the widget's ancestors + are kept non-native even though the widget itself is native. + + \value WA_X11NetWmWindowTypeDesktop Adds _NET_WM_WINDOW_TYPE_DESKTOP to the + window's _NET_WM_WINDOW_TYPE X11 window property.

Since + using a sheet implies window modality, the recommended + way is to use QWidget::setWindowModality(), or + QDialog::open(), instead. + + \value Drawer Indicates that the widget is a Macintosh drawer. + + \value Popup Indicates that the widget is a pop-up top-level + window, i.e. that it is modal, but has a window + system frame appropriate for pop-up menus. + + \value Tool Indicates that the widget is a tool window. A tool + window is often a small window with a smaller than + usual title bar and decoration, typically used for + collections of tool buttons. It there is a parent, + the tool window will always be kept on top of it. + If there isn't a parent, you may consider using + Qt::WindowStaysOnTopHint as well. If the window + system supports it, a tool window can be decorated + with a somewhat lighter frame. It can also be + combined with Qt::FramelessWindowHint. + \br + \br + On Mac OS X, tool windows correspond to the + \l{http://developer.apple.com/documentation/Carbon/Conceptual/HandlingWindowsControls/hitb-wind_cont_concept/chapter_2_section_2.html}{Floating} + class of windows. This means that the window lives on a + level above normal windows; it impossible to put a normal + window on top of it. By default, tool windows will disappear + when the application is inactive. This can be controlled by + the Qt::WA_MacAlwaysShowToolWindow attribute. + + \value ToolTip Indicates that the widget is a tooltip. This is + used internally to implement + \l{QWidget::toolTip}{tooltips}. + + \value SplashScreen Indicates that the window is a splash screen. + This is the default type for QSplashScreen. + + \value Desktop Indicates that this widget is the desktop. This + is the type for QDesktopWidget. + + \value SubWindow Indicates that this widget is a sub-window, such + as a QMdiSubWindow widget. + + There are also a number of flags which you can use to customize + the appearance of top-level windows. These have no effect on other + windows: + + \value MSWindowsFixedSizeDialogHint Gives the window a thin dialog border on Windows. + This style is traditionally used for fixed-size dialogs. + + \value MSWindowsOwnDC Gives the window its own display + context on Windows. + + \value X11BypassWindowManagerHint Bypass the window + manager completely. This results in a borderless window + that is not managed at all (i.e., no keyboard input unless + you call QWidget::activateWindow() manually). + + \value FramelessWindowHint Produces a borderless window. + The user cannot move or resize a borderless window via the window + system. On X11, the result of the flag is dependent on the window manager and its + ability to understand Motif and/or NETWM hints. Most existing + modern window managers can handle this. + + The \c CustomizeWindowHint flag is used to enable customization of + the window controls. This flag must be set to allow the \c + WindowTitleHint, \c WindowSystemMenuHint, \c + WindowMinimizeButtonHint, \c WindowMaximizeButtonHint and \c + WindowCloseButtonHint flags to be changed. + + \value CustomizeWindowHint Turns off the default window title hints. + + \value WindowTitleHint Gives the window a title bar. + + \value WindowSystemMenuHint Adds a window system menu, and + possibly a close button (for example on Mac). If you need to hide + or show a close button, it is more portable to use \c + WindowCloseButtonHint. + + \value WindowMinimizeButtonHint Adds a minimize button. On + some platforms this implies Qt::WindowSystemMenuHint for it to work. + + \value WindowMaximizeButtonHint Adds a maximize button. On + some platforms this implies Qt::WindowSystemMenuHint for it to work. + + \value WindowMinMaxButtonsHint Adds a minimize and a maximize + button. On some platforms this implies Qt::WindowSystemMenuHint for it to work. + + \value WindowCloseButtonHint Adds a close button. On + some platforms this implies Qt::WindowSystemMenuHint for it + to work. + + \value WindowContextHelpButtonHint Adds a context help button to dialogs. + On some platforms this implies Qt::WindowSystemMenuHint for it to work. + + \value MacWindowToolBarButtonHint On Mac OS X adds a tool bar button (i.e., + the oblong button that is on the top right of windows that have toolbars. + + \value BypassGraphicsProxyWidget Prevents the window and its children from + automatically embedding themselves into a QGraphicsProxyWidget if the + parent widget is already embedded. You can set this flag if you + want your widget to always be a toplevel widget on the desktop, + regardless of whether the parent widget is embedded in a scene or + not. + + \value WindowShadeButtonHint + + \value WindowStaysOnTopHint Informs the window system that the + window should stay on top of all other windows. Note that + on some window managers on X11 you also have to pass + Qt::X11BypassWindowManagerHint for this flag to work + correctly. + + \value WindowStaysOnBottomHint Informs the window system that the + window should stay on bottom of all other windows. Note + that on X11 this hint will work only in window managers + that support _NET_WM_STATE_BELOW atom. If a window always + on the bottom has a parent, the parent will also be left on + the bottom.

You can use these algorithms with any \l {container + class} that provides STL-style iterators, including Qt's QList, + QLinkedList, QVector, QMap, and QHash classes. + + These functions have taken their inspiration from similar + functions available in the STL \c <algorithm> header. Most of them + have a direct STL equivalent; for example, qCopyBackward() is the + same as STL's copy_backward() algorithm. + + If STL is available on all your target platforms, you can use the + STL algorithms instead of their Qt counterparts. One reason why + you might want to use the STL algorithms is that STL provides + dozens and dozens of algorithms, whereas Qt only provides the most + important ones, making no attempt to duplicate functionality that + is already provided by the C++ standard. + + Most algorithms take \l {STL-style iterators} as parameters. The + algorithms are generic in the sense that they aren't bound to a + specific iterator class; you can use them with any iterators that + meet a certain set of requirements. + + Let's take the qFill() algorithm as an example. Unlike QVector, + QList has no fill() function that can be used to fill a list with + a particular value. If you need that functionality, you can use + qFill(): + + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 0 + + qFill() takes a begin iterator, an end iterator, and a value. + In the example above, we pass \c list.begin() and \c list.end() + as the begin and end iterators, but this doesn't have to be + the case: + + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 1 + + Different algorithms can have different requirements for the + iterators they accept. For example, qFill() accepts two + \l {forward iterators}. The iterator types required are specified + for each algorithm. If an iterator of the wrong type is passed (for + example, if QList::ConstIterator is passed as an \l {output + iterator}), you will always get a compiler error, although not + necessarily a very informative one. + + Some algorithms have special requirements on the value type + stored in the containers. For example, qEqual() requires that the + value type supports operator==(), which it uses to compare items. + Similarly, qDeleteAll() requires that the value type is a + non-const pointer type (for example, QWidget *). The value type + requirements are specified for each algorithm, and the compiler + will produce an error if a requirement isn't met. + + \target binaryFind example + + The generic algorithms can be used on other container classes + than those provided by Qt and STL. The syntax of STL-style + iterators is modeled after C++ pointers, so it's possible to use + plain arrays as containers and plain pointers as iterators. A + common idiom is to use qBinaryFind() together with two static + arrays: one that contains a list of keys, and another that + contains a list of associated values. For example, the following + code will look up an HTML entity (e.g., \c &) in the \c + name_table array and return the corresponding Unicode value from + the \c value_table if the entity is recognized: + + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 2 + + This kind of code is for advanced users only; for most + applications, a QMap- or QHash-based approach would work just as + well: + + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 3 + + \section1 Types of Iterators + + The algorithms have certain requirements on the iterator types + they accept, and these are specified individually for each + function. The compiler will produce an error if a requirement + isn't met. + + \section2 Input Iterators + + An \e{input iterator} is an iterator that can be used for reading + data sequentially from a container. It must provide the following + operators: \c{==} and \c{!=} for comparing two iterators, unary + \c{*} for retrieving the value stored in the item, and prefix + \c{++} for advancing to the next item. + + The Qt containers' iterator types (const and non-const) are all + input iterators. + + \section2 Output Iterators + + An \e{output iterator} is an iterator that can be used for + writing data sequentially to a container or to some output + stream. It must provide the following operators: unary \c{*} for + writing a value (i.e., \c{*it = val}) and prefix \c{++} for + advancing to the next item. + + The Qt containers' non-const iterator types are all output + iterators. + + \section2 Forward Iterators + + A \e{forward iterator} is an iterator that meets the requirements + of both input iterators and output iterators. + + The Qt containers' non-const iterator types are all forward + iterators. + + \section2 Bidirectional Iterators + + A \e{bidirectional iterator} is an iterator that meets the + requirements of forward iterators but that in addition supports + prefix \c{--} for iterating backward. + + The Qt containers' non-const iterator types are all bidirectional + iterators. + + \section2 Random Access Iterators + + The last category, \e{random access iterators}, is the most + powerful type of iterator. It supports all the requirements of a + bidirectional iterator, and supports the following operations: + + \table + \row \i \c{i += n} \i advances iterator \c i by \c n positions + \row \i \c{i -= n} \i moves iterator \c i back by \c n positions + \row \i \c{i + n} or \c{n + i} \i returns the iterator for the item \c + n positions ahead of iterator \c i + \row \i \c{i - n} \i returns the iterator for the item \c n positions behind of iterator \c i + \row \i \c{i - j} \i returns the number of items between iterators \c i and \c j + \row \i \c{i[n]} \i same as \c{*(i + n)} + \row \i \c{i < j} \i returns true if iterator \c j comes after iterator \c i + \endtable + + QList and QVector's non-const iterator types are random access iterators. + + \sa {container classes}, <QtGlobal> +*/ + +/*! \fn OutputIterator qCopy(InputIterator begin1, InputIterator end1, OutputIterator begin2) + \relates <QtAlgorithms> + + Copies the items from range [\a begin1, \a end1) to range [\a + begin2, ...), in the order in which they appear. + + The item at position \a begin1 is assigned to that at position \a + begin2; the item at position \a begin1 + 1 is assigned to that at + position \a begin2 + 1; and so on. + + Example: + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 4 + + \sa qCopyBackward(), {input iterators}, {output iterators} +*/ + +/*! \fn BiIterator2 qCopyBackward(BiIterator1 begin1, BiIterator1 end1, BiIterator2 end2) + \relates <QtAlgorithms> + + Copies the items from range [\a begin1, \a end1) to range [..., + \a end2). + + The item at position \a end1 - 1 is assigned to that at position + \a end2 - 1; the item at position \a end1 - 2 is assigned to that + at position \a end2 - 2; and so on. + + Example: + \snippet doc/src/snippets/code/doc_src_qalgorithms.qdoc 5 + + \sa qCopy(), {bidirectional iterators} +*/ + +/*! \fn bool qEqual(InputIterator1 begin1, InputIterator1 end1, InputIterator2 begin2) + \relates <QtAlgorithms> + + Compares the items in the range [\a begin1, \a end1) with the + items in the range [\a begin2, ...).

For example, here's the + definition of a cache that stores objects of type Employee + associated with an integer key: + + \snippet doc/src/snippets/code/doc_src_qcache.qdoc 0 + + Here's how to insert an object in the cache: + + \snippet doc/src/snippets/code/doc_src_qcache.qdoc 1 + + The advantage of using QCache over some other key-based data + structure (such as QMap or QHash) is that QCache automatically + takes ownership of the objects that are inserted into the cache and + deletes them to make room for new objects, if necessary. When + inserting an object into the cache, you can specify a \e{cost}, + which should bear some approximate relationship to the amount of + memory taken by the object. When the sum of all objects' costs + (totalCost()) exceeds the cache's limit (maxCost()), QCache starts + deleting objects in the cache to keep under the limit, starting with + less recently accessed objects. + + By default, QCache's maxCost() is 100. You can specify a + different value in the QCache constructor: + + \snippet doc/src/snippets/code/doc_src_qcache.qdoc 2 + + Each time you call insert(), you can specify a cost as third + argument (after the key and a pointer to the object to insert). + After the call, the inserted object is owned by the QCache, which + may delete it at any time to make room for other objects. + + To look up objects in the cache, use object() or + operator[](). This function looks up an object by its key, and + returns either a pointer to the cached object (which is owned by + the cache) or 0. + + If you want to remove an object from the cache for a particular key, + call remove(). This will also delete the object. If you want to + remove an object from the cache without the QCache deleting it, use + take(). + + \sa QPixmapCache, QHash, QMap +*/ + +/*! \fn QCache::QCache(int maxCost = 100) + + Constructs a cache whose contents will never have a total cost + greater than \a maxCost. +*/ + +/*! \fn QCache::~QCache() + + Destroys the cache.

Stack allocation has the advantage that + it is much faster than heap allocation. + + Example: + \snippet doc/src/snippets/code/doc_src_qvarlengtharray.qdoc 2 + + In the example above, QVarLengthArray will preallocate 1024 + elements on the stack and use them unless \c{n + 1} is greater + than 1024. If you omit the second template argument, + QVarLengthArray's default of 256 is used. + + QVarLengthArray's value type must be an \l{assignable data type}. + This covers most data types that are commonly used, but the + compiler won't let you, for example, store a QWidget as a value; + instead, store a QWidget *. + + QVarLengthArray, like QVector, provides a resizable array data + structure.

(QVector always does.) + + \o QVector uses \l{implicit sharing} as a memory optimization. + QVarLengthArray doesn't provide that feature; however, it + usually produces slightly better performance due to reduced + overhead, especially in tight loops. + \endlist + + In summary, QVarLengthArray is a low-level optimization class + that only makes sense in very specific cases.

For an + application, one of the available screens is the primary screen, i.e. + the screen where the main widget resides (see primaryScreen).

The number of screens + available is returned by screenCount, and the screenCountChanged + signal is emitted when screens are added or removed during runtime. + The screen number that a particular point or widget is located in + is returned by screenNumber(). + + Widgets provided by Qt use this class, for example, to place + tooltips, menus and dialog boxes according to the parent or + application widget.

Its default coordinate system has + its origin located at the top-left position. X increases to the + right and Y increases downwards. The unit is one pixel. + + The drawing capabilities of QPaintDevice are currently implemented + by the QWidget, QImage, QPixmap, QGLPixelBuffer, QPicture, and + QPrinter subclasses. + + To implement support for a new backend, you must derive from + QPaintDevice and reimplement the virtual paintEngine() function to + tell QPainter which paint engine should be used to draw on this + particular device. Note that you also must create a corresponding + paint engine to be able to draw on the device, i.e derive from + QPaintEngine and reimplement its virtual functions. + + \warning Qt requires that a QApplication object exists before + any paint devices can be created. Paint devices access window + system resources, and these resources are not initialized before + an application object is created. + + The QPaintDevice class provides several functions returning the + various device metrics: The depth() function returns its bit depth + (number of bit planes). The height() function returns its height + in default coordinate system units (e.g. pixels for QPixmap and + QWidget) while heightMM() returns the height of the device in + millimeters. Similiarily, the width() and widthMM() functions + return the width of the device in default coordinate system units + and in millimeters, respectively. Alternatively, the protected + metric() function can be used to retrieve the metric information + by specifying the desired PaintDeviceMetric as argument. + + The logicalDpiX() and logicalDpiY() functions return the + horizontal and vertical resolution of the device in dots per + inch. The physicalDpiX() and physicalDpiY() functions also return + the resolution of the device in dots per inch, but note that if + the logical and vertical resolution differ, the corresponding + QPaintEngine must handle the mapping.

Define a template + instance Q3AsciiCache\<X\> to create a cache that operates on + pointers to X (X*). + + A cache is a least recently used (LRU) list of cache items. The + cache items are accessed via \c char* keys. For Unicode keys use + the Q3Cache template instead, which uses QString keys. A Q3Cache + has the same performace as a Q3AsciiCache. + + Each cache item has a cost. The sum of item costs, totalCost(), + will not exceed the maximum cache cost, maxCost(). If inserting a + new item would cause the total cost to exceed the maximum cost, + the least recently used items in the cache are removed. + + Apart from insert(), by far the most important function is find() + (which also exists as operator[]()). This function looks up an + item, returns it, and by default marks it as being the most + recently used item. + + There are also methods to remove() or take() an object from the + cache. Calling \link Q3PtrCollection::setAutoDelete() + setAutoDelete(TRUE)\endlink tells the cache to delete items that + are removed. The default is to not delete items when then are + removed (i.e., remove() and take() are equivalent). + + When inserting an item into the cache, only the pointer is copied, + not the item itself. This is called a shallow copy. It is possible + to make the cache copy all of the item's data (known as a deep + copy) when an item is inserted. insert() calls the virtual + function Q3PtrCollection::newItem() for the item to be inserted. + Inherit a cache and reimplement newItem() if you want deep copies. + + When removing a cache item the virtual function + Q3PtrCollection::deleteItem() is called.

Each + cache item has a key and a certain cost. The sum of item costs, + totalCost(), never exceeds the maximum cache cost, maxCost(). If + inserting a new item would cause the total cost to exceed the + maximum cost, the least recently used items in the cache are + removed. + + Q3Cache is a template class. Q3Cache\<X\> defines a cache that + operates on pointers to X, or X*. + + Apart from insert(), by far the most important function is find() + (which also exists as operator[]()). This function looks up an + item, returns it, and by default marks it as being the most + recently used item. + + There are also methods to remove() or take() an object from the + cache. Calling setAutoDelete(TRUE) for a cache tells it to delete + items that are removed. The default is to not delete items when + they are removed (i.e., remove() and take() are equivalent). + + When inserting an item into the cache, only the pointer is copied, + not the item itself. This is called a shallow copy. It is possible + to make the cache copy all of the item's data (known as a deep + copy) when an item is inserted. insert() calls the virtual + function Q3PtrCollection::newItem() for the item to be inserted. + Inherit a cache and reimplement newItem() if you want deep copies. + + When removing a cache item, the virtual function + Q3PtrCollection::deleteItem() is called. The default + implementation deletes the item if auto-deletion is enabled, and + does nothing otherwise. + + There is a Q3CacheIterator that can be used to traverse the items + in the cache in arbitrary order. + + In Q3Cache, the cache items are accessed via QString keys, which + are Unicode strings. If you want to use non-Unicode, plain 8-bit + \c char* keys, use the Q3AsciiCache template.

Define a template + instance Q3Dict\<X\> to create a dictionary that operates on + pointers to X (X *). + + A dictionary is a collection of key-value pairs. The key is a + QString used for insertion, removal and lookup. The value is a + pointer. Dictionaries provide very fast insertion and lookup. + + If you want to use non-Unicode, plain 8-bit \c char* keys, use the + Q3AsciiDict template. A Q3Dict has the same performance as a + Q3AsciiDict. If you want to have a dictionary that maps QStrings to + QStrings use QMap. + + The size() of the dictionary is very important. In order to get + good performance, you should use a suitably large prime number. + Suitable means equal to or larger than the maximum expected number + of dictionary items. Size is set in the constructor but may be + changed with resize(). + + Items are inserted with insert(); 0 pointers cannot be inserted. + Items are removed with remove(). All the items in a dictionary can + be removed with clear(). The number of items in the dictionary is + returned by count(). If the dictionary contains no items isEmpty() + returns TRUE. You can change an item's value with replace(). Items + are looked up with operator[](), or with find() which return a + pointer to the value or 0 if the given key does not exist. You can + take an item out of the dictionary with take(). + + Calling setAutoDelete(TRUE) for a dictionary tells it to delete + items that are removed. The default behavior is not to delete + items when they are removed. + + When an item is inserted, the key is converted (hashed) to an + integer index into an internal hash array.

Define a template + instance Q3IntCache\<X\> to create a cache that operates on + pointers to X, or X*. + + A cache is a least recently used (LRU) list of cache items, + accessed via \c long keys. Each cache item has a cost. The sum + of item costs, totalCost(), will not exceed the maximum cache + cost, maxCost(). If inserting a new item would cause the total + cost to exceed the maximum cost, the least recently used items in + the cache are removed. + + Apart from insert(), by far the most important function is find() + (which also exists as operator[]). This function looks up an + item, returns it, and by default marks it as being the most + recently used item. + + There are also methods to remove() or take() an object from the + cache. Calling setAutoDelete(TRUE) for a cache tells it to delete + items that are removed. The default is to not delete items when + they are removed (i.e. remove() and take() are equivalent). + + When inserting an item into the cache, only the pointer is copied, + not the item itself.

Define a template + instance Q3MemArray\<X\> to create an array that contains X items. + + Q3MemArray stores the array elements directly in the array. It can + only deal with simple types (i.e. C++ types, structs, and classes + that have no constructors, destructors, or virtual functions). + Q3MemArray uses bitwise operations to copy and compare array + elements. + + The Q3PtrVector collection class is also a kind of array. Like most + old Qt collection classes, it uses pointers to the contained items. + + Q3MemArray uses explicit sharing with a + reference count. If more than one array shares common data and one + of the arrays is modified, all the arrays are modified. + + The benefit of sharing is that a program does not need to duplicate + data when it is not required, which results in lower memory use + and less copying of data. + + Example: + \snippet doc/src/snippets/code/doc_src_q3memarray.qdoc 0 + + Program output: + \snippet doc/src/snippets/code/doc_src_q3memarray.qdoc 1 + + Note concerning the use of Q3MemArray for manipulating structs or + classes: Compilers will often pad the size of structs of odd sizes + up to the nearest word boundary. This will then be the size + Q3MemArray will use for its bitwise element comparisons. Because + the remaining bytes will typically be uninitialized, this can + cause find() etc. to fail to find the element. Example: + + \snippet doc/src/snippets/code/doc_src_q3memarray.qdoc 2 + + To work around this, make sure that you use a struct where + sizeof() returns the same as the sum of the sizes of the members + either by changing the types of the struct members or by adding + dummy members. + + Q3MemArray data can be traversed by iterators (see begin() and + end()). The number of items is returned by count(). The array can + be resized with resize() and filled using fill(). + + You can make a shallow copy of the array with assign() (or + operator=()) and a deep copy with duplicate(). + + Search for values in the array with find() and contains(). For + sorted arrays (see sort()) you can search using bsearch(). + + You can set the data directly using setRawData() and + resetRawData(), although this requires care. +*/ + +/*! \fn Q3MemArray::operator QVector<type>() const + + Automatically converts the Q3MemArray<type> into a QVector<type>. +*/ + +/*! \typedef Q3MemArray::Iterator + A Q3MemArray iterator. + \sa begin() end() +*/ +/*! \typedef Q3MemArray::ConstIterator + A const Q3MemArray iterator. + \sa begin() end() +*/ +/*! \typedef Q3MemArray::ValueType + \internal +*/ + +/*! + \fn Q3MemArray::Q3MemArray() + + Constructs a null array. + + \sa isNull() +*/ + +/*! + \fn Q3MemArray::Q3MemArray( int size ) + + Constructs an array with room for \a size elements.

The + first item corresponds to index position 0. The current index is + -1 if the current item is 0. + + Items are inserted with prepend(), insert() or append(). Items are + removed with remove(), removeRef(), removeFirst() and + removeLast(). You can search for an item using find(), findNext(), + findRef() or findNextRef(). The list can be sorted with sort(). + You can count the number of occurrences of an item with contains() + or containsRef(). You can get a pointer to the current item with + current(), to an item at a particular index position in the list + with at() or to the first or last item with getFirst() and + getLast(). You can also iterate over the list with first(), + last(), next() and prev() (which all update current()). The list's + deletion property is set with setAutoDelete(). + + \target example + Example: + \snippet doc/src/snippets/code/doc_src_q3ptrlist.qdoc 0 + + The output is + \snippet doc/src/snippets/code/doc_src_q3ptrlist.qdoc 1 + + Q3PtrList has several member functions for traversing the list, but + using a Q3PtrListIterator can be more practical. Multiple list + iterators may traverse the same list, independently of each other + and of the current list item. + + In the example above we make the call setAutoDelete(true). + Enabling auto-deletion tells the list to delete items that are + removed. The default is to not delete items when they are removed + but this would cause a memory leak in the example because there + are no other references to the list items. + + When inserting an item into a list only the pointer is copied, not + the item itself, i.e. a shallow copy. It is possible to make the + list copy all of the item's data (deep copy) when an item is + inserted. insert(), inSort() and append() call the virtual + function Q3PtrCollection::newItem() for the item to be inserted. + Inherit a list and reimplement newItem() to have deep copies. + + When removing an item from a list, the virtual function + Q3PtrCollection::deleteItem() is called. Q3PtrList's default + implementation is to delete the item if auto-deletion is enabled. + + The virtual function compareItems() can be reimplemented to + compare two list items. This function is called from all list + functions that need to compare list items, for instance + remove(const type*). If you only want to deal with pointers, there + are functions that compare pointers instead, for instance + removeRef(const type*). These functions are somewhat faster than + those that call compareItems(). + + List items are stored as \c void* in an internal Q3LNode, which + also holds pointers to the next and previous list items. The + functions currentNode(), removeNode(), and takeNode() operate + directly on the Q3LNode, but they should be used with care. The + data component of the node is available through Q3LNode::getData(). + + The Q3StrList class is a list of \c char*. + It reimplements newItem(), deleteItem() and compareItems().

Note that Q3ValueList does not + store pointers to the members of the list; it holds a copy of + every member. This is why these kinds of classes are called "value + based"; Q3PtrList and Q3Dict are "pointer based". + + Q3ValueList contains and manages a collection of objects of type T + and provides iterators that allow the contained objects to be + addressed. Q3ValueList owns the contained items. For more relaxed + ownership semantics, see Q3PtrCollection and friends which are + pointer-based containers. + + Some classes cannot be used within a Q3ValueList, for example, all + classes derived from QObject and thus all classes that implement + widgets. Only values can be used in a Q3ValueList. To qualify as a + value the class must provide: + \list + \i a copy constructor; + \i an assignment operator; + \i a default constructor, i.e. a constructor that does not take any arguments. + \endlist + + Note that C++ defaults to field-by-field assignment operators and + copy constructors if no explicit version is supplied. In many + cases this is sufficient. + + In addition, some compilers (e.g. Sun CC) might require that the + class provides an equality operator (operator==()). + + Q3ValueList's function naming is consistent with the other Qt + classes (e.g. count(), isEmpty()). Q3ValueList also provides extra + functions for compatibility with STL algorithms, such as size() + and empty(). Programmers already familiar with the STL \c list may + prefer to use the STL-compatible functions. + + Example: + \snippet doc/src/snippets/code/doc_src_q3valuelist.qdoc 0 + + + Notice that the latest changes to Mary's salary did not affect the + value in the list because the list created a copy of Mary's entry. + + There are several ways to find items in the list. The begin() and + end() functions return iterators to the beginning and end of the + list. The advantage of getting an iterator is that you can move + forward or backward from this position by + incrementing/decrementing the iterator. The iterator returned by + end() points to the item which is one \e past the last item in the + container. The past-the-end iterator is still associated with the + list it belongs to, however it is \e not dereferenceable; + operator*() will not return a well-defined value. If the list is + empty(), the iterator returned by begin() will equal the iterator + returned by end(). + + It is safe to have multiple iterators a the list at the same + time. If some member of the list is removed, only iterators + pointing to the removed member become invalid. Inserting into the + list does not invalidate any iterator. For convenience, the + function last() returns a reference to the last item in the list, + and first() returns a reference to the first item. If the + list is empty(), both last() and first() have undefined behavior + (your application will crash or do unpredictable things). Use + last() and first() with caution, for example: + + \snippet doc/src/snippets/code/doc_src_q3valuelist.qdoc 1 + + Because Q3ValueList is value-based there is no need to be careful + about deleting items in the list. The list holds its own copies + and will free them if the corresponding member or the list itself + is deleted. You can force the list to free all of its items with + clear(). + + Q3ValueList is shared implicitly, which means it can be copied in + constant time, i.e. O(1). If multiple Q3ValueList instances share + the same data and one needs to modify its contents, this modifying + instance makes a copy and modifies its private copy; therefore it + does not affect the other instances; this takes O(n) time. This is + often called "copy on write". If a Q3ValueList is being used in a + multi-threaded program, you must protect all access to the list. + See \l QMutex. + + There are several ways to insert items into the list. The + prepend() and append() functions insert items at the beginning and + the end of the list respectively. The insert() function comes in + several flavors and can be used to add one or more items at + specific positions within the list. + + Items can also be removed from the list in several ways. There + are several variants of the remove() function, which removes a + specific item from the list. The remove() function will find and + remove items according to a specific item value. + + \sa Q3ValueListIterator +*/ + +/*! \typedef Q3ValueList::iterator + The list's iterator type, Q3ValueListIterator. */ +/*! \typedef Q3ValueList::const_iterator + The list's const iterator type, Q3ValueListConstIterator. */ +/*! \typedef Q3ValueList::value_type + The type of the object stored in the list, T. */ +/*! \typedef Q3ValueList::pointer + The pointer to T type. */ +/*! \typedef Q3ValueList::const_pointer + The const pointer to T type. */ +/*! \typedef Q3ValueList::reference + The reference to T type. */ +/*! \typedef Q3ValueList::const_reference + The const reference to T type. */ +/*! \typedef Q3ValueList::size_type + An unsigned integral type, used to represent various sizes. */ +/*! \typedef Q3ValueList::difference_type + \internal +*/ +/*! + \fn Q3ValueList::Q3ValueList() + + Constructs an empty list. +*/ + +/*! + \fn Q3ValueList::Q3ValueList( const Q3ValueList<T>& l ) + \fn Q3ValueList::Q3ValueList( const QList<T>& l ) + \fn Q3ValueList::Q3ValueList( const QLinkedList<T>& l ) + + Constructs a copy of \a l. +*/ + +/*! + \fn Q3ValueList::Q3ValueList( const std::list<T>& l ) + + Contructs a copy of \a l. + + This constructor is provided for compatibility with STL + containers. +*/ + +/*! + \fn Q3ValueList::~Q3ValueList() + + Destroys the list.

The + reason for this is that elements must to be copied into new + positions. + + Some classes cannot be used within a Q3ValueVector: for example, + all classes derived from QObject and thus all classes that + implement widgets. Only values can be used in a Q3ValueVector. To + qualify as a value the class must provide: + \list + \i a copy constructor; + \i an assignment operator; + \i a default constructor, i.e., a constructor that does not take any arguments. + \endlist + + Note that C++ defaults to field-by-field assignment operators and + copy constructors if no explicit version is supplied. In many + cases this is sufficient. + + Q3ValueVector uses an STL-like syntax to manipulate and address the + objects it contains. + + Example: + \snippet doc/src/snippets/code/doc_src_q3valuevector.qdoc 0 + + Program output: + \snippet doc/src/snippets/code/doc_src_q3valuevector.qdoc 1 + + As you can see, the most recent change to Joe's salary did not + affect the value in the vector because the vector created a copy + of Joe's entry. + + Many Qt functions return const value vectors; to iterate over + these you should make a copy and iterate over the copy. + + There are several ways to find items in the vector. The begin() + and end() functions return iterators to the beginning and end of + the vector. The advantage of getting an iterator is that you can + move forward or backward from this position by + incrementing/decrementing the iterator. The iterator returned by + end() points to the element which is one past the last element in + the container. The past-the-end iterator is still associated with + the vector it belongs to, however it is \e not dereferenceable; + operator*() will not return a well-defined value. If the vector is + empty(), the iterator returned by begin() will equal the iterator + returned by end(). + + The fastest way to access an element of a vector is by using + operator[]. This function provides random access and will return + a reference to the element located at the specified index. Thus, + you can access every element directly, in constant time, providing + you know the location of the element. It is undefined to access + an element that does not exist (your application will probably + crash). For example: + + \snippet doc/src/snippets/code/doc_src_q3valuevector.qdoc 2 + + Whenever inserting, removing or referencing elements in a vector, + always make sure you are referring to valid positions. For + example: + + \snippet doc/src/snippets/code/doc_src_q3valuevector.qdoc 3 + + The iterators provided by vector are random access iterators, + therefore you can use them with many generic algorithms, for + example, algorithms provided by the STL. + + It is safe to have multiple iterators on the vector at the same + time. Since Q3ValueVector manages memory dynamically, all iterators + can become invalid if a memory reallocation occurs. For example, + if some member of the vector is removed, iterators that point to + the removed element and to all following elements become + invalidated. Inserting into the middle of the vector will + invalidate all iterators. For convenience, the function back() + returns a reference to the last element in the vector, and front() + returns a reference to the first element. If the vector is + empty(), both back() and front() have undefined behavior (your + application will crash or do unpredictable things). Use back() and + front() with caution, for example: + + \snippet doc/src/snippets/code/doc_src_q3valuevector.qdoc 4 + + Because Q3ValueVector manages memory dynamically, it is recommended + that you contruct a vector with an initial size. Inserting and + removing elements happens fastest when: + \list + \i Inserting or removing elements happens at the end() of the + vector; + \i The vector does not need to allocate additional memory. + \endlist + + By creating a Q3ValueVector with a sufficiently large initial size, + there will be less memory allocations. Do not use an initial size + that is too big, since it will still take time to construct all + the empty entries, and the extra space will be wasted if it is + never used. + + Because Q3ValueVector is value-based there is no need to be careful + about deleting elements in the vector. The vector holds its own + copies and will free them if the corresponding member or the + vector itself is deleted. You can force the vector to free all of + its items with clear(). + + Q3ValueVector is shared implicitly, which means it can be copied in + constant time. If multiple Q3ValueVector instances share the same + data and one needs to modify its contents, this modifying instance + makes a copy and modifies its private copy; it thus does not + affect the other instances. This is often called "copy on write". + If a Q3ValueVector is being used in a multi-threaded program, you + must protect all access to the vector. See QMutex. + + There are several ways to insert elements into the vector. The + push_back() function insert elements into the end of the vector, + and is usually fastest. The insert() function can be used to add + elements at specific positions within the vector. + + Items can be also be removed from the vector in several ways. + There are several variants of the erase() function which removes a + specific element, or range of elements, from the vector. + + Q3ValueVector stores its elements in contiguous memory.
