* RSS listing example: prefer setDevice() over addData(readAll())Edward Welbourne2023-05-161-13/+9
| | | | | | | | | | | | | | | The network reply is a QIODevice, so the QXmlStreamReader can be set to read from it directly, which it might potentially do incrementally, rather than by reading all the data in one go. In the process, change the set-up of the reply to first check that it got a valid URL, then check it got a reply, before doing things with that reply.

The example is referenced in a few parts of the documentation, but there are equivalent snippets in the trivial and license wizard examples, so point at those instead, and add some relevant API usage where needed.

| | | | | | | | | | | | | | | | Rename it to "Translucent Background", as that's what the example shows how to do. And modern applications shouldn't use a (binary) mask to create shaped windows. Instead, set the TranslucentBackground attribute, don't paint pixels that should be fully transparent and use anti-aliased or semi-opaque painting for pixels that should be translucent. Adjust the example and documentation accordingly. Move the statment that widget masks create coarse visual clipping to the QWidget::setMask documentation.

* rsslisting example: fix bug in construction of title stringEdward Welbourne2023-05-151-4/+3
| | | | | | | | | | | | | | | | | | The correct time to clear titleString and linkString is at the start of the item element, to avoid not only the left-overs from a previous item but also any stray titles and links that don't belong to any item. The channel element, that contains the items, may also have title and link elements. This, indeed, lead to the first entry in the displayed table having a "Qt Blog" prefix on its blog-post's title. Fortunately the link was already being set, usually to empty, due to the lack of rss:about attributes on item elements.

* Update cbordump image to a higher-resolution oneEdward Welbourne2023-05-091-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Incidentally using reversed video, too, as that's what came naturally to the terminal I was using. File is smaller, but text in the new image is considerably more readable and the image is bigger. The examples guideline calls for an image giving some idea what the example is about, with a 4:3 or 5:4 aspect ratio. An image shorter than its width wasn't practical, and getting a useful amount of information in a height less than 3/2 of the width would have required widening into blank space purely to satisfy the aspect ratio. The prior image's ratio was about 12:7, the new one's is roughly 2:3. The old image showed the start of cbordump -a output, which is rather less illuminating than the default output of formatted data; it's also rather verbose, so was cut off part way through. It does, however, illustrate how the annotated form might be useful for debug purposes. The image also had a lot of blank space to the right of the text of interest, wasting roughly half of its width; it could easily have been cropped to 1:1 without loss of information. As example data-set, it used ../savegame/save.dat, but without any hint to how to generate that. I decided to include a hint to how to generate a CBOR data file to dump, then show the standard output and only the beginnings of the annotated output, as the latter (even on its own) would make the aspect ratio considerably taller. In the context of the standard display, the preamble of the annotated one gives a reasonable feel for what's going on, without belabouring the point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JSON, unlike, say, QDataStream, allows building up objects independent of some central object, and combining them into a QJsonDocument later. This suggests returning QJsonObjects from a toJson() const method instead of having the caller supply a QJsonObject. Doing it this way enables transparent move semantics to kick in, too. For deserialization, use a fromJson() named constructor for value-like classes (where identity doesn't matter, only equality). Keep using read(), too, and add a note to explain when to use which form. Also, avoid the triple lookup from if (json.contains("key") && json["key"].isSoughtType()) mFoo = json["key"].toSoughtType(); by using C++17 if-with-initializer and showing the trick with Undefined never being of isSoughtType(): if (const QJsonValue v = json["key"]; v.isSoughtType()) mFoo = v.toSoughtType(); Adjust the discussion to match the new code, up the copyright years and rename some qdoc snippet markers from nondescript [0]/[1] to [toJson]/[fromJson].

If the user decides to close the application while the async continuation is executed, the next continuation will be accessing data from the destroyed Images object. Fix it by using QtConcurrent::run() to do the "heavy" work in a separate thread, and use a QFutureWatcher to handle the results of the async execution. Update the example documentation accordingly. After this patch the example still shows the usage of continuations and onCanceled()/onFailed() handlers. However, it now does not illustrate the usage of different launch policies and continuation contexts.

| | | | | | | | | | | | | | | | | | | | | | | | Old examples inherited from Qt 4 tend to set some state, such as enabling the depth test or culling, in initializeGL(). Newer examples tend not to do this; they rather set the necessary state in paintGL(). This mattered little (or not at all) in the past, but with WebAssembly and WebGL there are limitations in the GL context management in the wasm platform plugin. Under certain conditions, esp. when QOffscreenSurface is involved, it looks like the same native context gets reused, which means there is a chance of unexpected changes to the current state between calls to initializeGL() and paintGL(). (and also between paintGL() calls) See QWasmOpenGLContext for details. Update the textures example the same way we did for the cube one. Add a note to the QOpenGLWidget docs about this problem.

* Doc: Use the \examplecategory macro to tag examplesTopi Reinio2023-04-118-8/+8
| | | | | | | | | | | | | | | | The '\meta category' command was used for tagging examples with a specific category, used in Qt Creators Welcome mode. As we want to also generate lists of examples belonging to a category elsewhere in the documentation, replace the command with a macro that expands to the original \meta command and also adds the example to a group using the \ingroup command. This way, the category names can be used as arguments to the \generatelist or \annotatedlist commands.

* Fix pointer mismatch after QList::move() in tooltip exampleAxel Spoerl2023-03-283-24/+36
| | | | | | | | | | | | | | | | | | | | | | | | The tooltip example moves shape items within a QWidget. Shape items are stored in a QList of objects. When an item is moved, its pointer is taken from the QList and stored in a member variable. To have the moved item on the bottom of the list, QList::move() is called. This operation re-arranges the list objects, and the member variable starts pointing at a wrong object. This patch changes the list from a list of objects, to a list of pointers. Shape items are therefore allocated on the heap. A destructor is added to free the heap with qDeleteAll. The example's documentation is adapted accordingly and a snippet for the destructor is added. As a drive-by, int is replaced by qsizetype where it was used as an index of a QList.
