* Fix composition for windows with alphaLaszlo Agocs2014-08-131-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | While we will cover the entire surface with our textured quads, the clear is still necessary in order to make top-levels with TranslucentBackground render correctly: We don't want to blend transparent areas with undefined content that is in the surface's framebuffer. Blending is problematic for alpha values. We now prevent the blended alpha from being written out. This ensures that in examples like qquickviewcomparison, where the backingstore image contains an alpha of 0.5 while the QQuickWidget texture 1.0, the result is still an alpha value of 1.0 in the final image. Writing out an alpha of 0.5 would break on systems where windows get an alpha buffer by default. hellogl2 can now take a --transparent parameter which makes the QOpenGLWidget being cleared to transparent in order to verify it works in combination with Qt::WA_TranslucentBackground. The swapped red and blue problem is also corrected. RGBA8888 does not need swizzling. The only format that needs this is RGB32.

* Make QOpenGLWidget publicLaszlo Agocs2014-08-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | QOpenGLWidget is now public. In addition Qt::WA_AlwaysStackOnTop is introduced to support the special case of semi-transparent QOpenGLWidget or QQuickWidget on top of regular widgets. hellogl_es2 becomes the qopenglwidget example. This example performs painting both via QPainter and native GL commands and has the OpenGL widget combined with other, normal widgets. The widget stack receives some changes when it comes to renderToTexture widgets like QQuickWidget and QOpenGLWidget. Calling update() will now result in a paint event, which is essential for QOpenGLWidget since we want it to behave like a regular widget. The dirty region handling is extended specially for such widgets due to performance reasons. (an OpenGL content update must not result in any backingstore painting, and is thus handled as a different kind of dirtiness) [ChangeLog] Added QOpenGLWidget. This widget serves as a replacement for QGLWidget.

* Fix UI squishing when using QWidget::setRenderToTextureJocelyn Turcotte2014-04-031-1/+1
| | | | | | | | | | When resizing a window, a window might not be resized synchronously with its backing store. We need to use the actual texture size as the transform to avoid stretching the rendered texture.

* Expose QPA API under qpa/*Girish Ramakrishnan2012-05-071-0/+102
The main reasons for doing this are: 1. _qpa.h end up in the master QtGui include file. QtGui is meant for userland applications. qpa code is neither binary nor source compatible. Inadvertant use of QPA api makes the user code binary-incompatible. 2. syncqt creates forwarding headers for non-private header files. This gives people the impression that this is public API. As discussed on the mailing list, even though QPA api is internal and subject to change, it needs to treated differently from private headers since they will be used by in-qtbase and out-of-qtbase plugins. This commit does the following: 1. The _qpa in QPA header files is dropped. 2. syncqt now treats any file with qplatform prefix as a special file and moves it to qpa/ directory. The recommended way of using QPA API in plugins is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API from multiple modules (for example, qplatformfoo might be in QtPrintSupport) 3. The user needs to explicitly add QT += <module>-private to get access to the qpa api. 4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo includes. This commit does not change the cpp filenames. This requires a more careful merging of existing non qpa cpp files and existing cpp files on a case by case basis. This can be done at anytime. The following files are not renamed as part of this changed but will be fixed as part of a future change: src/gui/kernel/qgenericpluginfactory_qpa.h src/gui/kernel/qgenericplugin_qpa.h src/gui/kernel/qwindowsysteminterface_qpa.h files were renamed using for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done includes were renamed using script for file in `find . -name "*.h" -or -name "*.cpp" -or -name "*.mm"`; do sed -i -e 's,.*#.*include.*<\(Qt.*/\)\?\(QPlatform.*\)>,#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.*"\(Qt.*/\)\?\(QPlatform.*\)",#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.* "\(qplatform.*\)_qpa.h",#include <qpa/\L\1.h>,g' \ -e 's,.*#.*include.*"\(qplatform.*\)_qpa_p.h",#include <qpa/\L\1_p.h>,g' \ -e 's,.*#.*include.*<\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)>,#include <qpa/\2\3>,g' \ -e 's,.*#.*include.*"\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)",#include <qpa/\2\3>,g' \ $file done Change-Id: I04a350314a45746e3911f54b3b21ad03315afb67 Reviewed-by: Morten Johan Sørvig <morten.sorvig@nokia.com> Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com> Reviewed-by: Friedemann Kleint <Friedemann.Kleint@nokia.com> Reviewed-by: Sean Harmer <sean.harmer@kdab.com> Reviewed-by: Lars Knoll <lars.knoll@nokia.com> Reviewed-by: Gunnar Sletta <gunnar.sletta@nokia.com>
