It is very simple to use: Make - your class inherit from it and use the subclass like any other - QWidget, except that you have the choice between using QPainter and - standard OpenGL rendering commands. - - QOpenGLWidget provides three convenient virtual functions that you - can reimplement in your subclass to perform the typical OpenGL - tasks: - - \list - \li paintGL() - Renders the OpenGL scene. Gets called whenever the widget - needs to be updated. - \li resizeGL() - Sets up the OpenGL viewport, projection, etc. Gets - called whenever the widget has been resized (and also when it - is shown for the first time because all newly created widgets get a - resize event automatically). - \li initializeGL() - Sets up the OpenGL resources and state. Gets called - once before the first time resizeGL() or paintGL() is called. - \endlist - - If you need to trigger a repaint from places other than paintGL() (a - typical example is when using \l{QTimer}{timers} to animate scenes), - you should call the widget's update() function to schedule an update. - - Your widget's OpenGL rendering context is made current when - paintGL(), resizeGL(), or initializeGL() is called. If you need to - call the standard OpenGL API functions from other places (e.g. in - your widget's constructor or in your own paint functions), you - must call makeCurrent() first. - - All rendering happens into an OpenGL framebuffer - object. makeCurrent() ensure that it is bound in the context. Keep - this in mind when creating and binding additional framebuffer - objects in the rendering code in paintGL(). Never re-bind the - framebuffer with ID 0. Instead, call defaultFramebufferObject() to - get the ID that should be bound. - - QOpenGLWidget allows using different OpenGL versions and profiles - when the platform supports it. Just set the requested format via - setFormat(). Keep in mind however that having multiple QOpenGLWidget - instances in the same window requires that they all use the same - format, or at least formats that do not make the contexts - non-sharable. To overcome this issue, prefer using - QSurfaceFormat::setDefaultFormat() instead of setFormat(). - - \note Calling QSurfaceFormat::setDefaultFormat() before constructing - the QApplication instance is mandatory on some platforms (for example, - \macos) when an OpenGL core profile context is requested. This is to - ensure that resource sharing between contexts stays functional as all - internal contexts are created using the correct version and profile. - - \section1 Painting Techniques - - As described above, subclass QOpenGLWidget to render pure 3D content in the - following way: - - \list - - \li Reimplement the initializeGL() and resizeGL() functions to - set up the OpenGL state and provide a perspective transformation. - - \li Reimplement paintGL() to paint the 3D scene, calling only - OpenGL functions. - - \endlist - - It is also possible to draw 2D graphics onto a QOpenGLWidget subclass using QPainter: - - \list - - \li In paintGL(), instead of issuing OpenGL commands, construct a QPainter - object for use on the widget. - - \li Draw primitives using QPainter's member functions. - - \li Direct OpenGL commands can still be issued. However, you must make sure - these are enclosed by a call to the painter's beginNativePainting() and - endNativePainting(). - - \endlist - - When performing drawing using QPainter only, it is also possible to perform - the painting like it is done for ordinary widgets: by reimplementing paintEvent(). - - \list - - \li Reimplement the paintEvent() function. - - \li Construct a QPainter object targeting the widget. Either pass the widget to the - constructor or the QPainter::begin() function. - - \li Draw primitives using QPainter's member functions. - - \li Painting finishes then the QPainter instance is destroyed. Alternatively, - call QPainter::end() explicitly. - - \endlist - - \section1 OpenGL Function Calls, Headers and QOpenGLFunctions - - When making OpenGL function calls, it is strongly recommended to avoid calling - the functions directly. Instead, prefer using QOpenGLFunctions (when making - portable applications) or the versioned variants (for example, - QOpenGLFunctions_3_2_Core and similar, when targeting modern, desktop-only - OpenGL). This way the application will work correctly in all Qt build - configurations, including the ones that perform dynamic OpenGL implementation - loading which means applications are not directly linking to an GL - implementation and thus direct function calls are not feasible. - - In paintGL() the current context is always accessible by caling - QOpenGLContext::currentContext(). From this context an already initialized, - ready-to-be-used QOpenGLFunctions instance is retrievable by calling - QOpenGLContext::functions(). An alternative to prefixing every GL call is to - inherit from QOpenGLFunctions and call - QOpenGLFunctions::initializeOpenGLFunctions() in initializeGL(). - - As for the OpenGL headers, note that in most cases there will be no need to - directly include any headers like GL.h. The OpenGL-related Qt headers will - include qopengl.h which will in turn include an appropriate header for the - system. This might be an OpenGL ES 3.x or 2.0 header, the highest version that - is available, or a system-provided gl.h. In addition, a copy of the extension - headers (called glext.h on some systems) is provided as part of Qt both for - OpenGL and OpenGL ES. These will get included automatically on platforms where - feasible. This means that constants and function pointer typedefs from ARB, - EXT, OES extensions are automatically available. - - \section1 Code Examples - - To get started, the simplest QOpenGLWidget subclass could like like the following: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 0 - - Alternatively, the prefixing of each and every OpenGL call can be avoided by deriving - from QOpenGLFunctions instead: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 1 - - To get a context compatible with a given OpenGL version or profile, or to - request depth and stencil buffers, call setFormat(): - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 2 - - With OpenGL 3.0+ contexts, when portability is not important, the versioned - QOpenGLFunctions variants give easy access to all the modern OpenGL functions - available in a given version: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 3 - - As described above, it is simpler and more robust to set the requested format - globally so that it applies to all windows and contexts during the lifetime of - the application. Below is an example of this: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 6 - - \section1 Relation to QGLWidget - - The legacy QtOpenGL module (classes prefixed with QGL) provides a widget - called QGLWidget. QOpenGLWidget is intended to be a modern replacement for - it. Therefore, especially in new applications, the general recommendation is - to use QOpenGLWidget. - - While the API is very similar, there is an important difference between the - two: QOpenGLWidget always renders offscreen, using framebuffer - objects. QGLWidget on the other hand uses a native window and surface. The - latter causes issues when using it in complex user interfaces since, depending - on the platform, such native child widgets may have various limitations, - regarding stacking orders for example. QOpenGLWidget avoids this by not - creating a separate native window. - - Due to being backed by a framebuffer object, the behavior of QOpenGLWidget is - very similar to QOpenGLWindow with the update behavior set to \c - PartialUpdateBlit or \c PartialUpdateBlend. This means that the contents are - preserved between paintGL() calls so that incremental rendering is - possible. With QGLWidget (and naturally QOpenGLWindow with the default update - behavior) this is usually not the case because swapping the buffers leaves the - back buffer with undefined contents. - - \note Most applications do not need incremental rendering because they will - render everything in the view on every paint call. In this case it is - important to call glClear() as early as possible in paintGL(). This helps - mobile GPUs that use a tile-based architecture to recognize that the tile - buffer does not need to be reloaded with the framebuffer's previous - contents. Omitting the clear call can lead to significant performance drops on - such systems. - - \note Avoid calling winId() on a QOpenGLWidget. This function triggers the creation of - a native window, resulting in reduced performance and possibly rendering glitches. - - \section1 Differences to QGLWidget - - Besides the main conceptual difference of being backed by a framebuffer object, there - are a number of smaller, internal differences between QOpenGLWidget and the older - QGLWidget: - - \list - - \li OpenGL state when invoking paintGL(). QOpenGLWidget sets up the viewport via - glViewport(). It does not perform any clearing. - - \li Clearing when starting to paint via QPainter. Unlike regular widgets, QGLWidget - defaulted to a value of \c true for - \l{QWidget::autoFillBackground()}{autoFillBackground}. It then performed clearing to the - palette's background color every time QPainter::begin() was used. QOpenGLWidget does not - follow this: \l{QWidget::autoFillBackground()}{autoFillBackground} defaults to false, - like for any other widget. The only exception is when being used as a viewport for other - widgets like QGraphicsView. In such a case autoFillBackground will be automatically set - to true to ensure compatibility with QGLWidget-based viewports. - - \endlist - - \section1 Multisampling - - To enable multisampling, set the number of requested samples on the - QSurfaceFormat that is passed to setFormat(). On systems that do not support - it the request may get ignored. - - Multisampling support requires support for multisampled renderbuffers and - framebuffer blits. On OpenGL ES 2.0 implementations it is likely that these - will not be present. This means that multisampling will not be available. With - modern OpenGL versions and OpenGL ES 3.0 and up this is usually not a problem - anymore. - - \section1 Threading - - Performing offscreen rendering on worker threads, for example to generate - textures that are then used in the GUI/main thread in paintGL(), are supported - by exposing the widget's QOpenGLContext so that additional contexts sharing - with it can be created on each thread. - - Drawing directly to the QOpenGLWidget's framebuffer outside the GUI/main - thread is possible by reimplementing paintEvent() to do nothing. The context's - thread affinity has to be changed via QObject::moveToThread(). After that, - makeCurrent() and doneCurrent() are usable on the worker thread. Be careful to - move the context back to the GUI/main thread afterwards. - - Unlike QGLWidget, triggering a buffer swap just for the QOpenGLWidget is not - possible since there is no real, onscreen native surface for it. Instead, it - is up to the widget stack to manage composition and buffer swaps on the gui - thread. When a thread is done updating the framebuffer, call update() \b{on - the GUI/main thread} to schedule composition. - - Extra care has to be taken to avoid using the framebuffer when the GUI/main - thread is performing compositing. The signals aboutToCompose() and - frameSwapped() will be emitted when the composition is starting and - ending. They are emitted on the GUI/main thread. This means that by using a - direct connection aboutToCompose() can block the GUI/main thread until the - worker thread has finished its rendering. After that, the worker thread must - perform no further rendering until the frameSwapped() signal is emitted. If - this is not acceptable, the worker thread has to implement a double buffering - mechanism. This involves drawing using an alternative render target, that is - fully controlled by the thread, e.g. an additional framebuffer object, and - blitting to the QOpenGLWidget's framebuffer at a suitable time. - - \section1 Context Sharing - - When multiple QOpenGLWidgets are added as children to the same top-level - widget, their contexts will share with each other. This does not apply for - QOpenGLWidget instances that belong to different windows. - - This means that all QOpenGLWidgets in the same window can access each other's - sharable resources, like textures, and there is no need for an extra "global - share" context, as was the case with QGLWidget. - - To set up sharing between QOpenGLWidget instances belonging to different - windows, set the Qt::AA_ShareOpenGLContexts application attribute before - instantiating QApplication. This will trigger sharing between all - QOpenGLWidget instances without any further steps. - - Creating extra QOpenGLContext instances that share resources like textures - with the QOpenGLWidget's context is also possible. Simply pass the pointer - returned from context() to QOpenGLContext::setShareContext() before calling - QOpenGLContext::create(). The resulting context can also be used on a - different thread, allowing threaded generation of textures and asynchronous - texture uploads. - - Note that QOpenGLWidget expects a standard conformant implementation of - resource sharing when it comes to the underlying graphics drivers. For - example, some drivers, in particular for mobile and embedded hardware, have - issues with setting up sharing between an existing context and others that are - created later. Some other drivers may behave in unexpected ways when trying to - utilize shared resources between different threads. - - \section1 Resource Initialization and Cleanup - - The QOpenGLWidget's associated OpenGL context is guaranteed to be current - whenever initializeGL() and paintGL() are invoked. Do not attempt to create - OpenGL resources before initializeGL() is called. For example, attempting to - compile shaders, initialize vertex buffer objects or upload texture data will - fail when done in a subclass's constructor. These operations must be deferred - to initializeGL(). Some of Qt's OpenGL helper classes, like QOpenGLBuffer or - QOpenGLVertexArrayObject, have a matching deferred behavior: they can be - instantiated without a context, but all initialization is deferred until a - create(), or similar, call. This means that they can be used as normal - (non-pointer) member variables in a QOpenGLWidget subclass, but the create() - or similar function can only be called from initializeGL(). Be aware however - that not all classes are designed like this. When in doubt, make the member - variable a pointer and create and destroy the instance dynamically in - initializeGL() and the destructor, respectively. - - Releasing the resources also needs the context to be current. Therefore - destructors that perform such cleanup are expected to call makeCurrent() - before moving on to destroy any OpenGL resources or wrappers. Avoid deferred - deletion via \l{QObject::deleteLater()}{deleteLater()} or the parenting - mechanism of QObject. There is no guarantee the correct context will be - current at the time the instance in question is really destroyed. - - A typical subclass will therefore often look like the following when it comes - to resource initialization and destruction: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 4 - - This is naturally not the only possible solution. One alternative is to use - the \l{QOpenGLContext::aboutToBeDestroyed()}{aboutToBeDestroyed()} signal of - QOpenGLContext. By connecting a slot, using direct connection, to this signal, - it is possible to perform cleanup whenever the the underlying native context - handle, or the entire QOpenGLContext instance, is going to be released. The - following snippet is in principle equivalent to the previous one: - - \snippet code/doc_gui_widgets_qopenglwidget.cpp 5 - - \note For widgets that change their associated top-level window multiple times - during their lifetime, a combined approach is essential. Whenever the widget - or a parent of it gets reparented so that the top-level window becomes - different, the widget's associated context is destroyed and a new one is - created. This is then followed by a call to initializeGL() where all OpenGL - resources must get reinitialized. Due to this the only option to perform - proper cleanup is to connect to the context's aboutToBeDestroyed() - signal. Note that the context in question may not be the current one when the - signal gets emitted. Therefore it is good practice to call makeCurrent() in - the connected slot. Additionally, the same cleanup steps must be performed - from the derived class' destructor, since the slot connected to the signal - will not get invoked when the widget is being destroyed. - - \note When Qt::AA_ShareOpenGLContexts is set, the widget's context never - changes, not even when reparenting because the widget's associated texture is - guaranteed to be accessible also from the new top-level's context. - - Proper cleanup is especially important due to context sharing. Even though - each QOpenGLWidget's associated context is destroyed together with the - QOpenGLWidget, the sharable resources in that context, like textures, will - stay valid until the top-level window, in which the QOpenGLWidget lived, is - destroyed. Additionally, settings like Qt::AA_ShareOpenGLContexts and some Qt - modules may trigger an even wider scope for sharing contexts, potentially - leading to keeping the resources in question alive for the entire lifetime of - the application. Therefore the safest and most robust is always to perform - explicit cleanup for all resources and resource wrappers used in the - QOpenGLWidget. - - \section1 Limitations - - Putting other widgets underneath and making the QOpenGLWidget transparent will - not lead to the expected results: The widgets underneath will not be - visible. This is because in practice the QOpenGLWidget is drawn before all - other regular, non-OpenGL widgets, and so see-through type of solutions are - not feasible. Other type of layouts, like having widgets on top of the - QOpenGLWidget, will function as expected. - - When absolutely necessary, this limitation can be overcome by setting the - Qt::WA_AlwaysStackOnTop attribute on the QOpenGLWidget. Be aware however that - this breaks stacking order, for example it will not be possible to have other - widgets on top of the QOpenGLWidget, so it should only be used in situations - where a semi-transparent QOpenGLWidget with other widgets visible underneath - is required. - - Note that this does not apply when there are no other widgets underneath and - the intention is to have a semi-transparent window. In that case the - traditional approach of setting Qt::WA_TranslucentBackground - on the top-level window is sufficient. Note that if the transparent areas are - only desired in the QOpenGLWidget, then Qt::WA_NoSystemBackground will need - to be turned back to \c false after enabling Qt::WA_TranslucentBackground. - Additionally, requesting an alpha channel for the QOpenGLWidget's context via - setFormat() may be necessary too, depending on the system. - - QOpenGLWidget supports multiple update behaviors, just like QOpenGLWindow. In - preserved mode the rendered content from the previous paintGL() call is - available in the next one, allowing incremental rendering. In non-preserved - mode the content is lost and paintGL() implementations are expected to redraw - everything in the view. - - Before Qt 5.5 the default behavior of QOpenGLWidget was to preserve the - rendered contents between paintGL() calls. Since Qt 5.5 the default behavior - is non-preserved because this provides better performance and the majority of - applications have no need for the previous content. This also resembles the - semantics of an OpenGL-based QWindow and matches the default behavior of - QOpenGLWindow in that the color and ancillary buffers are invalidated for - each frame. To restore the preserved behavior, call setUpdateBehavior() with - \c PartialUpdate. - - \section1 Alternatives - - Adding a QOpenGLWidget into a window turns on OpenGL-based - compositing for the entire window. In some special cases this may - not be ideal, and the old QGLWidget-style behavior with a separate, - native child window is desired. Desktop applications that understand - the limitations of this approach (for example when it comes to - overlaps, transparency, scroll views and MDI areas), can use - QOpenGLWindow with QWidget::createWindowContainer(). This is a - modern alternative to QGLWidget and is faster than QOpenGLWidget due - to the lack of the additional composition step. It is strongly - recommended to limit the usage of this approach to cases where there - is no other choice. Note that this option is not suitable for most - embedded and mobile platforms, and it is known to have issues on - certain desktop platforms (e.g. \macos) too. The stable, - cross-platform solution is always QOpenGLWidget. - - \e{OpenGL is a trademark of Silicon Graphics, Inc. in the United States and other - countries.} - - \sa QOpenGLFunctions, QOpenGLWindow, Qt::AA_ShareOpenGLContexts, UpdateBehavior -*/ - -/*! - \fn void QOpenGLWidget::aboutToCompose() - - This signal is emitted when the widget's top-level window is about to begin - composing the textures of its QOpenGLWidget children and the other widgets. -*/ - -/*! - \fn void QOpenGLWidget::frameSwapped() - - This signal is emitted after the widget's top-level window has finished - composition and returned from its potentially blocking - QOpenGLContext::swapBuffers() call. -*/ - -/*! - \fn void QOpenGLWidget::aboutToResize() - - This signal is emitted when the widget's size is changed and therefore the - framebuffer object is going to be recreated. -*/ - -/*! - \fn void QOpenGLWidget::resized() - - This signal is emitted right after the framebuffer object has been recreated - due to resizing the widget. -*/ - -/*! - \enum QOpenGLWidget::UpdateBehavior - \since 5.5 - - This enum describes the update semantics of QOpenGLWidget. - - \value NoPartialUpdate QOpenGLWidget will discard the - contents of the color buffer and the ancillary buffers after the - QOpenGLWidget is rendered to screen.
