* Android: Re-enable threaded renderingEskil Abrahamsen Blomfeldt2014-03-201-1/+2
| | | | | | | | | | | | | | | In Qt 5.2.x, the platform plugin inherited from the EGLFS platform plugin, so calling the super class implementation of hasCapability() would return true for ThreadedOpenGL. Since this link was removed in Qt 5.3, we would return false for all devices, giving us a large performance regression.

* Recognize RGBA8888 formats when converting to CGImageAllan Sandfeld Jensen2014-03-172-45/+17
| | | | | | | | | | | | | | | | | qt_mac_image_to_cgimage incorrectly assumes any 32bit QImage format is one ARGB32 form. This is no longer correct with the introduction of RGBA8888 format. This patch recognizes the formats a maps them to the native support for them in CGImage. It also removes a duplicate method. The codepath appears to be only used by the old coregraphics paintengine and MIME handling. Which means RGBA images are probably printed and copy/pasted incorrectly at the moment.

Update CocoaBackingStore to create a new buffer on window devicePixelRatio change. Use the QCocoaWindow::devicePixelRatio() implementation instead of a duplicate implementation in the backing store. The plan is to replace this implementation with one based on QUpdateWindowRequestEvent for Qt 5.4 Change-Id: I8e521c53df4ac90815613e730fe821996334721f Reviewed-by: Jørgen Lind <jorgen.lind@digia.com>
* | XCB plugin: query screen resources without _currentRolf Eike Beer2014-03-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xcb_randr_get_screen_resources() and xcb_randr_get_screen_resources_current() do basically the same, but for one case: if nothing has queried these information ever before. So if an application is the very first client ever to connect to an X server it may just return nothing. A call to xcb_randr_get_screen_info_reply() will then cause the X server to allocate the needed information and send an update notification, resulting in a second QXcbScreen being created, but the other one is still around and probably used. The behavior I observed with a simple test application was that the application was not visible on the screen when it was the first client ever on the X server. Killing the application and starting it again made it work just fine.
