* Let QPlatformBackingStore handle its own QOpenGLContextTor Arne Vestbø2017-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | The resources allocated by QPlatformBackingStore are owned by the class, and should be allocated in a context the class also owns. This removes the asymmetry of having to pass in a context to composeAndFlush, while having to make the same context current before destroying the platform backingstore. The context owned by QPlatformBackingStore is shared with the associated window though a new QWindowPrivate::shareContext() API. The result is that on e.g. iOS, the backingstore does not need to tie the resource allocation of QPlatformBackingStore to the global share context, but can instead tie them to the per-window context, and hence clean them up after each window is closed.

* Flesh out and clean up QBackingStore documentationTor Arne Vestbø2017-07-141-2/+0
| | | | | | | | | | | | | | | | | | | | | | | Some of the functions had wording that suggested people subclass QBackingStore, probably because the docs came from QWindowSurface in QWS times. Clarify the role of the region, window, and offset arguments to flush(), in the case of flushing child windows. Document that paintDevice() is only valid after calling beginPaint(), and should not be cached. Although our own QRasterWindow, and the rasterwindow example, both allow backingstores for child windows, and it works in practice on a few platforms, we keep the documentation stating that they should only be used for top level windows, until we've verified and formalized support for this across platforms.

* Compose renderToTexture widgets with sRGB when neededLaszlo Agocs2017-02-261-1/+2
| | | | | | | | | | | Just requesting an sRGB texture for a QOpenGLWidget does not lead to anything useful when it comes to the end result, the content will just get darkened. For proper operation the target window's default framebuffer must be sRGB capable and linearization during blending must be enabled.

| | | | | | | | | | | Regression from 2d2d9078, which assumed the code in QBackingStore::beginPaint would apply to macOS as well, but QHighDpiScaling::isActive() is only active when Qt does the high DPI scaling, so we never hit the resize() code-path.

* Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.

* Enable QPlatformBackingStore::toImage() when QT_NO_OPENGL is definedAndy Nichols2016-04-301-0/+2
| | | | | | | | | | | There are cases where you would want to grab the contents of a QWidget with a QSurfaceType of Raster, and in the case of a -no-opengl build there is no way to get the contents of a QBackingStore. The toImage() function was unnecessarily lumped into the QT_NO_OPENGL ifdef, so this commit removes this truncation of the API.

* Prevent continuous painting with viewport QOpenGLWidgetLaszlo Agocs2014-12-181-2/+9
| | | | | | | | | | | | | | | | | | | | | Add the source widget to the texture list (may be null for custom compositor implementations that add textures not belonging to actual widgets). This allows us to do proper checks with the dirtyRenderToTextureWidgets list. As a result paint events are only sent to a QOpenGLWidget if (1) there was an update() for it or (2) it was actually marked dirty. (2) was previously behaving differently: the widget got a paint event when anything in the window has changed. This is fine for naive animating OpenGL code but less ideal for QGraphicsView. Bool properties like stacksOnTop are now stored in a flags value to prevent future explosion of texture list fields and parameters.

* 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.

* 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>
