* Updated license headersJani Heikkinen2016-01-151-14/+20
| | | | | | | | | | | From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/ Updated license headers to use new LGPL header instead of LGPL21 one (in those files which will be under LGPL v3) Change-Id: I046ec3e47b1876cd7b4b0353a576b352e3a946d9 Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com>
* eglfs: Handle custom platform window implementations betterLaszlo Agocs2015-10-141-2/+4
| | | | | | | | | | | | | | Backends may want to subclass QEglFSWindow and reimplement resetSurface() and similar. Make it possible to do this by moving window creation to the device integration interface, similarly to screens. In addition to customizing the windows, some backends may want to disable the dependency on surfaceless contexts when using offscreen windows (i.e. pbuffer surfaces). Make this possible too.

* Disable surfaceless QOffscreenSurface with MesaLaszlo Agocs2015-06-221-1/+12
| | | | | | | | | | | With Intel at least Mesa is unable to handle surfaceless contexts in glReadPixels(). This cripples QOpenGLFramebufferObject::toImage() and potentially others too.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Utilize EGL_KHR_surfaceless_context in QOffscreenSurface when availableLaszlo Agocs2015-02-021-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use it also in the context initialization code which also relied on pbuffers until now. This is safe to do since QOffscreenSurface is deliberately kept minimal: we only support it for rendering to FBOs or uploading textures, it is quite useless for any rendering type of operation. Therefore simply not creating a surface when the extension is available is viable and should not break anything. While we should have done this a long time ago, the real inspiration now is to avoid crashes with some bad EGL implementations. Mesa in particular tends to crash in its interal configuration handling when trying to create a pbuffer surface with more exotic attributes, for example with multisampling enabled. Just getting rid of those properties is not an option since the resulting pbuffer would not be compatible with the existing context. Therefore our only option is to avoid the pbuffer altogether. There's a so-far-ignored patch for Mesa http://patchwork.freedesktop.org/patch/38100/ which tries to solve some of this but it turns out it is not sufficient to avoid problems with the multisampled case. So to avoid more headache, we just stop using pbuffers there. [ChangeLog][QtGui] QOffscreenSurface is now relying on EGL_KHR_surfaceless_context when available, and avoids creating a pbuffer surface when the extension is present.

* eglfs: Move reusable functionality to eglconvenienceLaszlo Agocs2014-01-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | The cursor implementation is generic GL(ES) code that should be shared by all the present and future egl-based embedded platform plugins. Follow the pattern of QEGLPlatformContext and move this class into eglconvenience as QEGLPlatformCursor. Similarly, the common bits from the context implementation context are moved back to EGLPlatformContext. eglconvenience has now base classes for integration, screen, window, etc. too. By using these, eglfs becomes much smaller and cleaner. This also paves the way for creating new, separate EGL-based platform plugins for Android, embedded Linux, etc. Also added some documentation to each of the base classes. devicediscovery is now fixed to be usable on any platform. The implementation in this case is naturally a dummy one. This finally allows using it from anywhere without myriads of ugly ifdefs.

* Added QOffscreenSurface class.Yoann Lopes2013-02-181-0/+76
Inherits QSurface and allows to use OpenGL from an arbitrary thread. Platform plugins can implement QPlatformOffscreenSurface, otherwise an invisible QWindow is used by QOffscreenSurface. This patch includes an implementation of QOffscreenSurface for XCB and EglFS platform plugins using pbuffers.
