| | * eglfs: Fix raster windowsLaszlo Agocs2019-08-071-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also sanitize the initial WebAssembly hack. Both eglfs and wasm lack the concept of true raster windows. A QWindow with RasterSurface is rendered with OpenGL no matter what. The two platforms took two different approaches to work around the rest of the machinery: - wasm disabled the QOpenGLContext warning for non-OpenGL QWindows, - eglfs forced the QWindow surfaceType to OpenGLSurface whenever it was originally set to RasterSurface. Now, the latter breaks since c4e9eabc309a275efc222f4127f31ba4677259b7, leaving all raster window applications failing on eglfs, because flush in the backingstore is now checking the surface type and disallows OpenGLSurface windows. (just like how QOpenGLContext disallows RasterSurface windows) To solve all this correctly, introduce a new platform capability, OpenGLOnRasterSurface, and remove the special handling in the platform plugins.

| * iOS: Harden logic for when it's safe to use the graphics hardwareTor Arne Vestbø2017-12-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To fix QTBUG-52493 we tied the exposed state of a window to the application being in the foreground. This has the result of a visible flash of black between hiding the launch screen and showing the first frame of the application, as the application is still waiting for UIApplicationStateActive to begin rendering, which happens after iOS hides the launch screen. According to the iOS OpenGL ES Programming Guide, it should be safe to render GL in UIApplicationStateInactive as well, and even in UIApplicationStateBackground, as long as the rendering finishes before the UIApplicationDidEnterBackgroundNotification returns. To ensure that we catch any bugs in this area, checks have been added that verify that no rendering happens while in the background state.

|/ | | | | | | | | | | | | | The problem of the check is that it makes Qt non compliant with OpenGL thread affinity semantics. One is allowed to make a GL context current on any thread, without the Qt-specific idea of moving the QOpenGLContext to that thread first. Moreover, the move is plain impossible if the user needs to handle the context to 3rd party code which assumes the context to have GL semantics. Add an application flag to disable that.

* Expose GLES 3.0 and 3.1 functionsLaszlo Agocs2015-07-231-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the approach we already do for some GLES 3.0 functions we can provide a cross-platform, cross-GL-GLES wrapper for ES 3.0 and 3.1 functions too. Applications only have to take extra care about the version requests (context version and version directives in shader code), the rest of their code can stay the same across desktop/mobile/embedded, even when ES 3 functions are used. The new functions are placed to a new subclass which is placed between QOpenGLFunctions and the internal QOpenGLExtensions. This is necessary because, unlike with QOpenGLFunctions, there is no guarantee that these functions are always available in all configurations. When running on desktop OpenGL, we resolve as usual. If the OpenGL version contains the function in question, either in core or as an extension, it will all just work. This is handy because it does not rely on 4.x extensions like GL_ARB_ESx_compatibility, and so ES 3.0 functions will be functional on OpenGL 3.x systems too by just setting a 3.x version number in the QSurfaceFormat. We will no longer qFatal on broken systems where the driver returns a 3.0 or 3.1 context without the corresponding functions present. Instead, we show a warning and gracefully fall back to resolving as usual, via eglGetProcAddress or similar. For functions that are available in ES2 as an extension this may just work fine. Added also an example that runs identically both with OpenGL and OpenGL ES 3 and utilizes some ES 3.0 features like instanced drawing. [ChangeLog] Added QOpenGLExtraFunctions providing OpenGL ES 3.0 and 3.1 function wrappers in a cross-platform manner.

* Fix incorrect FBO bindings with QOpenGLWidgetLaszlo Agocs2015-03-301-3/+17
| | | | | | | | | | | | | | QOpenGLContext::defaultFramebufferObject() knows nothing about QOpenGLWidget and QQuickWidget. The problem is that this function (and others that rely on it) is expected to give the widget's backing FBO in paintGL() and friends. To overcome this, we have to provide a way for such widgets that indicate what is the expected "default fbo".

* Make versioned OpenGL functions working with the subclass patternLaszlo Agocs2015-03-271-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QOpenGLFunctions allows both deriving from it and getting an instance via QOpenGLContext::functions(). Unsurprisingly a large number of users attempt to use the versioned function wrappers in the same way. Unfortunately this approach was not that well supported. Besides some potential base class exporting issues the real blocker for QOpenGLWidget - or any versionfunction subclass whose associated context changes during its lifetime - is that the functions instances could only be initialized once. Unlike instances retrieved via QOpenGLContext::versionFunctions(), instances created "manually" were not deinitialized upon the destruction of the associated context because context did not know about them. A pattern like initializeOpenGLFunctions(); delete context; create new context and make it current initializeOpenGLFunctions(); is working fine in QOpenGLFunctions-derived classes but not with the versioned ones. To overcome this, start registering such instances to the context too. QOpenGLContext::destroy() can then reset the internal state so a subsequent initializeOpenGLFunctions() will reinitialize properly instead of bailing out mistakenly thinking that everything is ready to use.
