* Don't rely on QRasterWindow::resizeEvent for marking window dirtyTor Arne Vestbø2024-02-011-3/+7
| | | | | | | | | | | | | | | | | The de-virtualization gotcha might result in client code not calling QRasterWindow::resizeEvent, which we use for dirty state management after e0eb2818face4ffb7dafd87464f355d4654b7be0. In practice this wasn't an issue, because QPaintDeviceWindow handles paint events by calling markWindowAsDirty first, but we should not rely on this. Instead plumb the resize event to QPaintDeviceWindowPrivate, which QRasterWindow implements and can override the behavior of. Pick-to: 6.5 6.6 6.7 Change-Id: I5c0747da10f0275b77f56be32690d796fa48cdb4 Reviewed-by: Volker Hilsheimer <[email protected]>
* Avoid extending dirty region in beginPaintTor Arne Vestbø2023-09-221-3/+9
| | | | | | | | | | | | | | | | | | | | | | When the raster window is resized, we need to resize the backingstore, and make sure we repaint the entire window. We defer the backingstore resize to beginPaint, in case multiple resize events come in before we have a chance to paint, but we can't defer the invalidation of the paint device window, because QPaintDeviceWindowPrivate::paint() has already subtracted the paint region from its dirty region at this point. Invalidating yet again will result in the dirty region of window not clearing fully until after the final resize, and when that happens we will also repaint the window with the wrong dirty region, based on the window's original size. My moving the window invalidation to the resize event, while keeping the deferred backingstore resize we avoid this problem.

* Delete QRasterWindow backingstore while window is still aliveTor Arne Vestbø2017-04-041-0/+8
| | | | | | | | | | | | | | | | The platform backingstore might need access to the window that the backingstore was created for, e.g. for makingCurrent to release OpenGL resources. In that case leaving it to the QRasterWindowPrivate destructor would be too late, as the QWindow was gone. This was seen on iOS, where the backingstore inherits QRasterBackingStore, and uses composeAndFlush to composit via GL. The raster backingstore cleans up these GL resources in its destructor, so the QIOSBackingStore destructor makes sure that the GL context is current for the window, resulting in a crash since the window is long gone by then.

* Enable non-integer device pixel ratioMorten Johan Sørvig2015-07-301-2/+0
| | | | | | | | | | | | | | | | | | | | Work around QPaintDevice::metric's int return type by adding a new metric that returns a scaled devicePixelRatio. Choose a scale factor that gives us more than enough range. The QPaintDevice::devicePixelRatio() convenience accessor is public API and can unfortunately not be changed to return a qreal. Add devicePixelRatioF() which returns the (unscaled) devicePixelRatio. Change all call sites of QPaintDevice::devicePixelRatio() to use QPainDevice::devicePixelRatioF().

* Introduce QRasterWindowLaszlo Agocs2014-08-051-0/+136
A simple convenience class providing a QWindow that has a paintEvent and supports opening a painter on itself. It behaves exactly like QOpenGLWindow in this respect, which is not surprising since they share the same base class (QPaintDeviceWindow). QRasterWindow does not however have any OpenGL dependencies and will be present in -no-opengl builds too. [ChangeLog] Added QRasterWindow, a thin convenience wrapper for a QWindow on which a QPainter can be opened.
