* QWaylandShmBackingStore: Don't clear new buffers in beginPaintKai Uwe Broulik2024-03-051-2/+2
| | | | | | | | | QFile::resize done upon creation of the buffer already ensures the buffer is filled with zeroes, so there is no need to paint it transparent if the buffer had just been created.

* QWaylandShmBackingStore: Split buffer preparation into dedicated methodKai Uwe Broulik2024-02-151-2/+1
| | | | | | | | | | | Drop "resize(QRect)" since it is ambiguous with the resize coming from QPlatformBackingStore. This allows to ensure a back buffer from multiple places, such as the upcoming "scroll" support.

* QWaylandShmBackingStore: Preserve buffer contents between framesKai Uwe Broulik2024-01-061-0/+4
| | | | | | | | | | | Doing a memcpy is quite expensive, particularly when only a small region of the buffer (such as a blinking cursor) actually changed. Instead, keep track of the damaged region and paint only what actually changed into the buffer to be used.

* Replace scale with devicePixelRatio for non-integer scalingJungi Byun2021-03-251-1/+1
| | | | | | | | | | | | | | | The 'scale' event from wayland cannot support non-integer scaling which was originally supported in Qt. As default, devicePixelRatio follows the 'scale' so that the high DPI still works as the mechanism in Wayland. But if non-integer scaling factor such as 150% is needed, it can be supported to override the devicePixelRatio.

* Don't commit same buffer multiple timesPaul Olav Tvete2018-08-081-0/+2
| | | | | | | | | | | | | | | | In Qt we call flush() when we think the window might need to be updated. It is also possible to trigger a flush while painting. Two fixes: 1) If there are attempted flushes between beginPaint() and endPaint, queue them up, and do them in endPaint(). 2) Make sure we only commit the buffer once: after that the compositor owns the buffer, and it can repaint on its own.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old logic didn't care to listen for wl_buffer.release events so it always drew in the same buffer, potentially resulting in tearing if the compositor was scanning out the buffer at the same time. Instead properly cycle between a few buffers and don't reuse the same one until the release event was received. The old code also used to throttle the redraws, unless the buffer was changing, that is unless the window was getting resized. This is now lost, and no throttling is ever done. Doing it properly, by waiting for the frame callback before committing the new buffer shows very noticeable lags with many applications when resizing, because they paint many times per resize event, so they fall behind the cursor. A proper fix will be to implement the support for requestUpdate(), and using it in the applications.

* | Implement high-dpi supportMorten Johan Sorvig2014-12-171-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | | Wayland 1.2 added support for display scaling, where wl_output has a "scale" event informing the the client that the compositor will scale the output surfaces by the given factor. The client then has the option of providing large surfaces to match the target pixel densety and bypass the compositor's scaling. This is done by calling wl_surface::set_buffer_scale. Re-use the current high-dpi support in Qt by implementing devicePixelRatio() for QWaylandScreen and QWaylandWindow. Provide high resolution buffers both for raster and OpenGL graphics. Introduce a new coordinate system: buffer coordinates, which is related to the window coordinate system via an "int scale" scale factor. This scale factor corresponds to Qts qreal devicePixelRatio, but we keep the name and the type in the QtWayland implementation.

* Fix shm windows sometimes not showing after being hiddenGiulio Camuffo2014-10-061-0/+1
| | | | | | | | | | | | | | | QWaylandShmBackingStore installs a frame callback on flush, and subsequent flushes will not attach a new buffer until the callback is fired. If the window is hidden while we're waiting for the callback, we attach a NULL buffer, so the compositor will not redraw the surface and will not fire the frame callback. When showing the window again the backing store's flush() will wait indefinitely for the frame callback to attach its buffer. To fix it destroy the frame callback when the window is hidden. This was easily noticeable when fast switching between popup menus. Change-Id: Ic0c71ed79e2fab9faf452f63b05bc4576ea9a3ba Reviewed-by: Jørgen Lind <jorgen.lind@digia.com>

| | | | | | | | | | | | | | | | | In an attempt to make QOpenGLWidget and QQuickWidget working on Wayland. Since Qt 5.3 all widget windows are of type RasterGLSurface (given that the plugin reports this capability which wayland will, with this patch). Such a window can behave either like a raster or an OpenGL window. This concept maps badly to platform plugins that have a rigid separation between raster and OpenGL platform window implementations. From now on, the OpenGL window implementation, that is used pretty much always, except for raw RasterSurface windows, must be prepared to behave like a raster window too, which involves having a backingstore.
