Instead of sending the repaint right away, register the need for a full repaint in the window and set it as part of the next sync phase.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the requested format (we don't have anything else since the platform window is gone) is wrong on EGL implementations that offer a different set of configurations for window and pbuffer surfaces, because we may end up with a pbuffer surface that is incompatible with the context/window due to having different color buffer sizes. To be absolutely sure that the surface is compatible, store the actual surface format so that it is available even after the platform window is gone.

| * Fix potential crash during shutdown for QQuickWindowsGunnar Sletta2014-03-171-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The cleanup() function would deregister the render loop from all windows the render loop had seen, but the render loop doesn't see windows until the window gets a showEvent and for some implementations it was removed as a result of hideEvent. So add explicit tracking to QSGRenderLoop which is managed by QQuickWindow's constructor and destructor. With this, we no longer need the lists from the subclasses, so these functions are removed again.

This results in crashes when used in combination with scenegraph-playgrounds's customcontext. Partially revert the change and instead clean up at the time of QApp::aboutToQuit and make sure we also disconnect cleanly from all QQuickWindows. This change also ensures that QSGRenderLoop::windowDestroyed() gets called for all QQuickWindows registered with the render loop. This ensures that rendering stops and that scene graph nodes and resources will be cleaned up regardless of whether the application has remembered to delete the window or not. This is a good thing as it makes the scene graph shutdown a bit cleaner. Change-Id: I9cb9093979f8eac05542f118a6ff9cfe5c84f745 Reviewed-by: Paul Olav Tvete <paul.tvete@digia.com>

* | Try to simplify the threaded render loop.Gunnar Sletta2014-03-241-7/+7
|/ | | | | | | | | | | | | | | | | | | | This beast has grown and grown for some time so it was time to take step back and look at a few of the problems again. 1. show/hide vs exposed/obscured. There is really no reason why we should even bother with show. It only adds the window to a list, we can do that in handleExposure and simplify things a bit. 2. Expose, polish, repaint, sync stuff was growing increasingly complex with multiple waits and several events and states interacting. So I merged the expose into the sync and passed that information along to the render thread. The render thread now knows if the sync is for a normal state-sync or an expose. For a normal sync it will wake GUI right away. For an expose, it waits until after the renderpass has completed and the frame is swapped.

* Use one render loop per QQuickWindowGunnar Sletta2013-10-301-12/+16
| | | | | | | | | | | | | | | | | | | See the task for the full reasoning behind this patch. The threaded renderloop has been refactored to have one window per thread. This is mostly a simplification of the current code path where for loops over multiple windows are turned into if (window). The QSGContext has been split into two classes, QSGRenderContext for which there is one per OpenGLContext. The rest of the patch is name changes and a couple of cleanups in the hopes of simplifying this change.

* Set incubation controller when a Window{} is loaded via QQmlApplicationEngineAlan Alpert2013-06-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | This was the one convenience that was lost when transitioning templates from QQuickView + Item{} to QQmlApplicationEngine + Window{}. As the default window incubation controller was tied to the first window's frameSwapped, we could easily run into a situation where a secondary window required incubation while the first window was idle. This would then starve the incubation controller. Instead make it so that the renderloop emits "timeToIncubate" once it is done with a renderpass over all windows, so the incubator gets to run once and exactly once per vsync when animating. The incubator logic was also flawed in that it could post a lot of events to itself as a result of incubatingObjectCountChanged and thus starve system events while processing incubation requests. Now we start a timer and don't start it again until we have completed an incubation pass.

* Improved animations in the new render loopGunnar Sletta2013-02-191-1/+4
| | | | | | | | | | | | | | | | | | | | To advance animations in line with vsync, we used a dedicated event from the rendering thread which we fired immediately after sync. This is a bit elaborate as we know in Gui when sync is complete and we can just animate there and then. This means we can remove all animation logic from the rendering thread, making it simpler. I also updated the syncAndRender pass so that it does not render anything if the scene graph reported no changes during the sync pass. This will prevent non-visual animations and property updates from triggering render passes which will save quite a few cycles.

* Complete rewrite of threaded render loop.Gunnar Sletta2013-01-181-0/+125
This change starts using the superior implementation of the scene graph render loop which has been worked on in the scenegraph-playground project for a while. It uses a far more straightforward locking/sync paradigm compared to the existing one and is less deadlock and error prone. It also enables the scene graph thread to run on its own when the GUI thread is blocked, enabling threaded animations. This changes also introduces a naming change inside Qt Quick from "Window Manager" -> "Render Loop" as that fits better to what the code does.
