gtk.gdk Constants the built-in constants of the gtk.gdk module This constant is available in PyGTK 2.16 and above. This consntant specifies which windowing backend GDK uses. It is similar to GDK_WINDOWING_* C macros. The constant value is one of the following strings (note that all values are lowercase): "x11" X Window System "win32" Microsoft Windows API "quartz" Mac OS X Quartz "directfb" Direct Frame Buffer on a UNIX-like system "?" Unknown (this can in theory happen if GTK+ library is newer than PyGTK) The Drag Action constants are used by gtk.gdk.DragContext objects to indicate what the destination should do with the dropped data. gtk.gdk.ACTION_DEFAULT gtk.gdk.ACTION_COPY Copy the data. gtk.gdk.ACTION_MOVE Move the data, i.e. first copy it, then delete it from the source using the DELETE target of the X selection protocol. gtk.gdk.ACTION_LINK Add a link to the data. Note that this is only useful if source and destination agree on what it means. gtk.gdk.ACTION_PRIVATE Special action which tells the source that the destination will do something that the source doesn't understand. gtk.gdk.ACTION_ASK Ask the user what to do with the data. The Device Axis constants describing the way in which a device axis (valuator) maps onto predefined valuator types. gtk.gdk.AXIS_IGNORE the axis is ignored. gtk.gdk.AXIS_X the axis is used as the x axis. gtk.gdk.AXIS_Y the axis is used as the y axis. gtk.gdk.AXIS_PRESSURE the axis is used for pressure information. gtk.gdk.AXIS_XTILT the axis is used for x tilt information. gtk.gdk.AXIS_YTILT the axis is used for y tilt information. gtk.gdk.AXIS_WHEEL the axis is used for wheel information. gtk.gdk.AXIS_LAST a constant equal to the numerically highest axis value. The Byte Order constants specify a set of values describing the possible byte-orders for storing pixel values in memory. gtk.gdk.LSB_FIRST The values are stored with the least-significant byte first. For instance, the 32-bit value 0xffeecc would be stored in memory as 0xcc, 0xee, 0xff, 0x00. gtk.gdk.MSB_FIRST The values are stored with the most-significant byte first. For instance, the 32-bit value 0xffeecc would be stored in memory as 0x00, 0xcc, 0xee, 0xff. The Cap Style constants specify how the end of lines are drawn. gtk.gdk.CAP_NOT_LAST The same as gtk.gdk.CAP_BUTT for lines of non-zero width but for zero width lines, the final point on the line will not be drawn. gtk.gdk.CAP_BUTT The ends of the lines are drawn squared off and extending to the coordinates of the end point. gtk.gdk.CAP_ROUND The ends of the lines are drawn as semicircles with the diameter equal to the line width and centered at the end point. gtk.gdk.CAP_PROJECTING The ends of the lines are drawn squared off and extending half the width of the line beyond the end point.

Note that each click also generates a gtk.gdk.BUTTON_PRESS event. gtk.gdk._3BUTTON_PRESS a mouse button has been clicked 3 times in a short period of time. Note that each click also generates a gtk.gdk.BUTTON_PRESS event. gtk.gdk.BUTTON_RELEASE a mouse button has been released. gtk.gdk.KEY_PRESS a key has been pressed. gtk.gdk.KEY_RELEASE a key has been released. gtk.gdk.ENTER_NOTIFY the pointer has entered the window. gtk.gdk.LEAVE_NOTIFY the pointer has left the window. gtk.gdk.FOCUS_CHANGE the keyboard focus has entered or left the window. gtk.gdk.CONFIGURE the size, position or stacking order of the window has changed. Note that PyGTK discards these events for gtk.gdk.WINDOW_CHILD windows. gtk.gdk.MAP the window has been mapped. gtk.gdk.UNMAP the window has been unmapped. gtk.gdk.PROPERTY_NOTIFY a property on the window has been changed or deleted. gtk.gdk.SELECTION_CLEAR the application has lost ownership of a selection. gtk.gdk.SELECTION_REQUEST another application has requested a selection. gtk.gdk.SELECTION_NOTIFY a selection has been received. gtk.gdk.PROXIMITY_IN an input device has moved into contact with a sensing surface (e.g. a touchscreen or graphics tablet). gtk.gdk.PROXIMITY_OUT an input device has moved out of contact with a sensing surface. gtk.gdk.DRAG_ENTER the mouse has entered the window while a drag is in progress. gtk.gdk.DRAG_LEAVE the mouse has left the window while a drag is in progress gtk.gdk.DRAG_MOTION the mouse has moved in the window while a drag is in progress. gtk.gdk.DRAG_STATUS the status of the drag operation initiated by the window has changed. gtk.gdk.DROP_START a drop operation onto the window has started. gtk.gdk.DROP_FINISHED the drop operation initiated by the window has completed. gtk.gdk.CLIENT_EVENT a message has been received from another application. gtk.gdk.VISIBILITY_NOTIFY the window visibility status has changed. gtk.gdk.NO_EXPOSE indicates that the source region was completely available when parts of a drawable were copied. This is not very useful. gtk.gdk.SCROLL a scroll had occurred for a window gtk.gdk.WINDOW_STATE the window state has changed gtk.gdk.SETTING a setting has changed The Extension Mode constants specify which extension events are desired for a particular widget. gtk.gdk.EXTENSION_EVENTS_NONE No extension events are desired. gtk.gdk.EXTENSION_EVENTS_ALL All extension events are desired. gtk.gdk.EXTENSION_EVENTS_CURSOR Extension events are desired only if a cursor will be displayed for the device. The Fill constants specify how primitives are drawn. gtk.gdk.SOLID draw with the foreground color. gtk.gdk.TILED draw with a tiled pixmap. gtk.gdk.STIPPLED draw using the stipple bitmap. Pixels corresponding to bits in the stipple bitmap that are set will be drawn in the foreground color; pixels corresponding to bits that are not set will be left untouched. gtk.gdk.OPAQUE_STIPPLED draw using the stipple bitmap. Pixels corresponding to bits in the stipple bitmap that are set will be drawn in the foreground color; pixels corresponding to bits that are not set will be drawn with the background color. The Fill Rule constants specify the method for determining which pixels are included in a region, when creating a GdkRegion from a polygon. The fill rule is only relevant for polygons which overlap themselves. Not used in PyGTK. gtk.gdk.EVEN_ODD_RULE Areas which are overlapped an odd number of times are included in the region, while areas overlapped an even number of times are not. gtk.gdk.WINDING_RULE Overlapping areas are always included. The Filter Return constants specify the result of filtering a native event. See the gtk.gdk.Window.add_filter() method for more information. gtk.gdk.FILTER_CONTINUE Event not handled, continue processing. gtk.gdk.FILTER_TRANSLATE Native event translated and stored into the gtk.gdk.Event passed in. gtk.gdk.FILTER_REMOVE Event handled, terminate processing. The Function constants specify how the bit values for the source pixels are combined with the bit values for destination pixels to produce the final result. The sixteen values here correspond to the 16 different possible 2x2 truth tables. Only a couple of these values are usually useful; for colored images, only gtk.gdk.COPY, gtk.gdk.XOR and gtk.gdk.INVERT are generally useful. For bitmaps, gtk.gdk.AND and gtk.gdk.OR are also useful. gtk.gdk.COPY gtk.gdk.INVERT gtk.gdk.XOR gtk.gdk.CLEAR gtk.gdk.AND gtk.gdk.AND_REVERSE. gtk.gdk.AND_INVERT gtk.gdk.NOOP gtk.gdk.OR gtk.gdk.EQUIV gtk.gdk.OR_REVERSE gtk.gdk.COPY_INVERT gtk.gdk.OR_INVERT gtk.gdk.NAND gtk.gdk.NOR gtk.gdk.SET The GC Values Mask flag constants are a set of bit flags used to specify which fields GdkGCValues structure are set.

The Gravity constants specify the reference point of a window and the meaning of coordinates passed to the gtk.Window.move() method. gtk.gdk.GRAVITY_NORTH_WEST The reference point is at the top left corner. gtk.gdk.GRAVITY_NORTH The reference point is in the middle of the top edge. gtk.gdk.GRAVITY_NORTH_EAST The reference point is at the top right corner. gtk.gdk.GRAVITY_WEST The reference point is at the middle of the left edge. gtk.gdk.GRAVITY_CENTER The reference point is at the center of the window. gtk.gdk.GRAVITY_EAST The reference point is at the middle of the right edge. gtk.gdk.GRAVITY_SOUTH_WEST The reference point is at the lower left corner. gtk.gdk.GRAVITY_SOUTH The reference point is at the middle of the lower edge. gtk.gdk.GRAVITY_SOUTH_EAST The reference point is at the lower right corner. gtk.gdk.GRAVITY_STATIC The reference point is at the top left corner of the window itself, ignoring window manager decorations. The Image Type constants specify the type of a gtk.gdk.Image. gtk.gdk.IMAGE_NORMAL The original X image type, which is quite slow since the image has to be transferred from the client to the server to display it. gtk.gdk.IMAGE_SHARED A faster image type, which uses shared memory to transfer the image data between client and server. However this will only be available if client and server are on the same machine and the shared memory extension is supported by the server. gtk.gdk.IMAGE_FASTEST Specifies that gtk.gdk.IMAGE_SHARED should be tried first, and if that fails then gtk.gdk.IMAGE_NORMAL will be used. The Input Condition constants are a set of bit-flags that specify conditions for which an input callback will be triggered. The three members of this enumeration correspond to the readfds, writefds, and exceptfds arguments to the select system call. gtk.gdk.INPUT_READ The file descriptor has become available for reading. (Or, as is standard in Unix, a socket or pipe was closed at the other end; this is the case if a subsequent read on the file descriptor returns a count of zero.) gtk.gdk.INPUT_WRITE The file descriptor has become available for writing. gtk.gdk.INPUT_EXCEPTION An exception was raised on the file descriptor. The Input Mode constants specify the mode of an input device. gtk.gdk.MODE_DISABLED the device is disabled and will not report any events. gtk.gdk.MODE_SCREEN the device is enabled. The device's coordinate space maps to the entire screen. gtk.gdk.MODE_WINDOW the device is enabled. The device's coordinate space is mapped to a single window. The manner in which this window is chosen is undefined, but it will typically be the same way in which the focus window for key events is determined. The Input Source constants specify the type of an input device in general terms. gtk.gdk.SOURCE_MOUSE the device is a mouse. (This will be reported for the core pointer, even if it is something else, such as a trackball.) gtk.gdk.SOURCE_PEN the device is a stylus of a graphics tablet or similar device. gtk.gdk.SOURCE_ERASER the device is an eraser. Typically, this would be the other end of a stylus on a graphics tablet. gtk.gdk.SOURCE_CURSOR the device is a graphics tablet "puck" or similar device. The Join Style constants specify how the joins between segments of a polygon are drawn. gtk.gdk.JOIN_MITER The sides of each line are extended to meet at an angle. gtk.gdk.JOIN_ROUND The sides of the two lines are joined by a circular arc. gtk.gdk.JOIN_BEVEL The sides of the two lines are joined by a straight line which makes an equal angle with each line. The Line Style constants specify how lines are drawn. gtk.gdk.LINE_SOLID Lines are drawn solid. gtk.gdk.LINE_ON_OFF_DASH Lines are drawn dashed where even segments are drawn but odd segments are not drawn. gtk.gdk.LINE_DOUBLE_DASH Lines are drawn dashed where even segments are drawn normally but odd segments are drawn in the background color if the fill style is gtk.gdk.SOLID, or in the background color masked by the stipple if the fill style is gtk.gdk.STIPPLED.

Typical modifier keys are Shift, Control, Meta, Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock. gtk.gdk.SHIFT_MASK The Shift key. gtk.gdk.LOCK_MASK A Lock key (depending on the modifier mapping of the X server this may either be CapsLock or ShiftLock). gtk.gdk.CONTROL_MASK The Control key. gtk.gdk.MOD1_MASK The fourth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier, but normally it is the Alt key). gtk.gdk.MOD2_MASK The fifth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier). gtk.gdk.MOD3_MASK The sixth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier). gtk.gdk.MOD4_MASK The seventh modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier). gtk.gdk.MOD5_MASK The eighth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier). gtk.gdk.BUTTON1_MASK The first mouse button. gtk.gdk.BUTTON2_MASK The second mouse button. gtk.gdk.BUTTON3_MASK The third mouse button. gtk.gdk.BUTTON4_MASK The fourth mouse button. gtk.gdk.BUTTON5_MASK The fifth mouse button. gtk.gdk.RELEASE_MASK Differentiates between (keyval, modifiers) pairs from key press and release events. gtk.gdk.MODIFIER_MASK all of the above The Notify Type constants specify the kind of crossing for the Crossing gtk.gdk.Event gtk.gdk.NOTIFY_ANCESTOR the window is entered from an ancestor or left toward an ancestor. gtk.gdk.NOTIFY_VIRTUAL the pointer moves between an ancestor and an inferior of the window. gtk.gdk.NOTIFY_INFERIOR the window is entered from an inferior or left toward an inferior. gtk.gdk.NOTIFY_NONLINEAR the window is entered from or left toward a window which is neither an ancestor nor an inferior. gtk.gdk.NOTIFY_NONLINEAR_VIRTUAL the pointer moves between two windows which are not ancestors of each other and the window is part of the ancestor chain between one of these windows and their least common ancestor. gtk.gdk.NOTIFY_UNKNOWN ??? The Overlap Type constants specify the possible values returned by the gtk.gdk.Region.rect_in() method. gtk.gdk.OVERLAP_RECTANGLE_IN The rectangle is inside the GdkRegion. gtk.gdk.OVERLAP_RECTANGLE_OUT The rectangle is outside the GdkRegion. gtk.gdk.OVERLAP_RECTANGLE_PART The rectangle is partly inside the GdkRegion.

The Subwindow Mode constants specify how drawing onto a window will affect child windows of that window. gtk.gdk.CLIP_BY_CHILDREN only draw onto the window itself not the subwindows. gtk.gdk.INCLUDE_INFERIORS draw onto the window and child windows. The Visibility State constants specify the visibility status of a window for the Visibility gtk.gdk.Event gtk.gdk.VISIBILITY_UNOBSCURED the window is completely visible. gtk.gdk.VISIBILITY_PARTIAL the window is partially visible. gtk.gdk.VISIBILITY_FULLY_OBSCURED the window is not visible at all. The Visual Type constants specify a set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display. gtk.gdk.VISUAL_STATIC_GRAY Each pixel value indexes a grayscale value directly. gtk.gdk.VISUAL_GRAYSCALE Each pixel is an index into a color map that maps pixel values into grayscale values. The color map can be changed by an application. gtk.gdk.VISUAL_STATIC_COLOR Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values. gtk.gdk.VISUAL_PSEUDO_COLOR Each pixel is an index into a color map that maps pixel values into rgb values. The color map can be changed by an application. gtk.gdk.VISUAL_TRUE_COLOR Each pixel value directly contains red, green, and blue components.

The Window Hints constants specify the fields of a GdkGeometry struct should be paid attention to. Also, the presence/absence of gtk.gdk.HINT_POS, gtk.gdk.HINT_USER_POS, and gtk.gdk.HINT_USER_SIZE is significant, though they don't directly refer to GdkGeometry fields. gtk.gdk.HINT_USER_POS will be set automatically by gtk.Window if you call the gtk.Window.move() method. gtk.gdk.HINT_USER_POS and gtk.gdk.HINT_USER_SIZE should be set if the user specified a size/position using a --geometry command-line argument; the gtk.Window.parse_geometry() method automatically sets these flags.

The Window Type Hint constants specify hints for the window manager that indicate what type of function the window has. The window manager can use this when determining decoration and behavior of the window. The hint must be set before mapping the window. gtk.gdk.WINDOW_TYPE_HINT_NORMAL A normal toplevel window. gtk.gdk.WINDOW_TYPE_HINT_DIALOG A dialog window. gtk.gdk.WINDOW_TYPE_HINT_MENU A window used to implement a menu. gtk.gdk.WINDOW_TYPE_HINT_TOOLBAR A window used to implement a toolbar. gtk.gdk.WINDOW_TYPE_HINT_SPLASHSCREEN A window used to implement a splash screen gtk.gdk.WINDOW_TYPE_HINT_UTILITY gtk.gdk.WINDOW_TYPE_HINT_DOCK A window used to implement a docking bar. gtk.gdk.WINDOW_TYPE_HINT_DESKTOP A window used to implement a desktop. gtk.gdk.WINDOW_TYPE_HINT_DROPDOWN_MENU A menu that belongs to a menubar. gtk.gdk.WINDOW_TYPE_HINT_POPUP_MENU A menu that does not belong to a menubar, e.g. a context menu. gtk.gdk.WINDOW_TYPE_HINT_TOOLTIP A tooltip. gtk.gdk.WINDOW_TYPE_HINT_NOTIFICATION A notification - typically a "bubble" that belongs to a status icon. gtk.gdk.WINDOW_TYPE_HINT_COMBO A popup from a combo box. gtk.gdk.WINDOW_TYPE_HINT_DND A window that is used to implement a DND cursor.
