* Fix clipRect interpretation in composited backingstoresLaszlo Agocs2016-02-011-3/+3
| | | | | | | | Empty clipRect means "clip away completely", not "no clipping". Task-number: QTBUG-50719 Change-Id: I6a9dd66130716a921fe9fc245582274e3c9718fe Reviewed-by: Paul Olav Tvete <paul.tvete@theqtcompany.com>
* eglfs: Sanitize the widget compositor's context handlingLaszlo Agocs2016-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | createPlatformOpenGLContext() used to silently set the widget compositor's context as the context to share resources with. This works mostly, but is the wrong level to enforce the resource sharing. For example, QOpenGLContext::shareGroup() becomes inconsistent since from QOpenGLContext's view there was no shareContext specified. The inability to test via shareGroup() is the reason eglfs started to show warnings when exiting applications. The resource sharing was in place on EGL level but QOpenGLContext knew nothing about it. Therefore, let's switch over to the way other components, f.ex. Web Engine use: set the internal global share context pointer to the widget compositor's context. This way everything remains consistent: the widget compositor's context is stored upon creating the main QEGLFSWindow, QWidget::shareContext() picks this up then, and as a result we have sharing set up on QOpenGLContext's level instead of sneaking it in in the QPlatformOpenGLContext implementation.

* Clip QOpenGLWidget and QQuickWidget correctlyLaszlo Agocs2015-06-011-4/+27
| | | | | | | | | | | | | Introduce support for the widgets' clipRect(). Right now render-to-texture widgets in scroll areas placed close to each other result in broken (non-existent) clipping. Similarly, stack-on-top widgets fail to clip when placed inside a scroll area. This is now corrected and the qopenglwidget example is enhanced to utilize a scroll area.

* Add support for grabWindow() on eglfs with widgetsLaszlo Agocs2015-03-161-3/+23
| | | | | | | | | | | | | For real OpenGL content it is still not supported because we have no reliable way to read back the contents at arbitrary times. Applications should rather use QQuickWindow::grabWindow() in that case. [ChangeLog][QtGui] Support for QScreen::grabWindow() is now available on embedded platforms (eglfs, linuxfb).

* 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>

* Add generic OpenGL compositor and backingstore bitsLaszlo Agocs2014-11-261-0/+243
By removing the EGL(FS) dependencies we get classes that can be used by any platform plugin that runs without a windowing system. Change-Id: If99b42de5a4da02bbef80863609b6d92c6734613 Reviewed-by: Jørgen Lind <jorgen.lind@theqtcompany.com>
