* examples: replace 'foreach' with 'range for'Anton Kudryavtsev2016-09-031-4/+4
| | | | | | | | While touching the code, replace QStringLiteral with QL1S in QStringBuilder expression. Change-Id: I2519b254d82453e1c9bd5b834c0bd78e5c026f83 Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>

* Fix rendercontrol example for screens with different dprLaszlo Agocs2015-04-281-1/+18
| | | | | | | | | | | | | | | | renderWindow() was not reimplemented in the example. This is pretty bad since renderWindowFor() fails to find a window and thus falls back to using the default device pixel ratio (which is the highest dpr present in the system). The result is broken content from Quick because it operates with a dpr of 2 any time a retina screen is connected, even when the example's own QWindow is placed on a normal screen. Add also a note to the QQuickRenderControl docs because it is easy to overlook.

| | | | | | | | | Even when the window size is not changing. This provides a useful example of connecting to the screenChanged() signal. Task-number: QTBUG-45613 Change-Id: I0652838d9c0cfec8b64b3422997159f385445b20 Reviewed-by: Gunnar Sletta <gunnar@sletta.org>
* Avoid showing garbage when resizing the rendercontrol exampleLaszlo Agocs2015-04-281-0/+1
| | | | | | | | | | | The threaded variant was working well since that triggers a render when resizing. The single threaded version lacked this and this resulted in showing garbage on OS X at least since the new FBO had undefined contents. Avoid this.

* Prevent windows outside the gui thread in rendercontrol exampleLaszlo Agocs2015-01-071-3/+3
| | | | | | | | | | | | | | | | In the multithreaded case we attempted to create QWindows outside the gui thread on platforms where QOffscreenSurface is backed by the hidden QWindow in the absence of a better solution. This has to be avoided. Therefore, pass a suitable surface from the gui thread instead. This will avoid "Attempting to create QWindow-based QOffscreenSurface outside the gui thread." type of warnings when running on OS X with --threaded.

* Support threading with QQuickRenderControlLaszlo Agocs2014-12-121-0/+273
Reorganize the rendercontrol example to demonstrate both the single and multi threaded approaches. A small helper function is introduced to the QQuickRenderControl API: The QSGRenderContext has to live on the render thread. Previously there was no way for applications to move it to the desired thread. This is now possible. Pass --threaded to the rendercontrol example to use a separate render thread. [ChangeLog][QtQuick] QQuickRenderControl can now be used to render the Qt Quick scene on a dedicated render thread, similarly to how the built-in threaded render loop operates.
