* Rename QWSI::handleWindowActivated to QWSI::handleFocusWindowChangedTor Arne Vestbø2023-11-231-4/+4
| | | | | | | | | | | | | | | | | | | A single QWindow is QGuiApplication::focusWindow() at a time, and this window is typically also QWindow::isActive(), but other windows may also be QWindow::isActive(). For example, we treat any sibling or ancestor of the focusWindow as being QWindow::isActive() as well. In addition, in the case of non-QWindow child windows, we may have to query the platform for the activation state, which means we also need a way for the platform to reflect changes in this state through QWSI. The current API for this, QWSI::handleWindowActivated, is in practice a focus window change API, so as a first step let's rename it to better reflect what it's doing.

* Fix link to platform window in QAndroidPlatformBackingStore::flush()Axel Spoerl2023-08-043-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Android QPA implementation requires a 1:1 link between a platform window and a platform backing store, to correctly flush a backing store to the screen. QAndroidPlatformBackingStore has a bool member m_backingStoreSet, to remember if this link exists. It defaults to false and is set to true, when setBackingStore() is called in the constructor. It falsely remains true, when a platform window is deleted, e.g. because a QWindow has been hidden. When the QWindow is shown again, a new Android platform window is created. With m_backingStoreSet still being true, this new platform window will never be associated with a backing store. As a consequence, it will never be displayed on the screen. The 1:1 relationship of an Android platform window and an Android backing store is neither ideal, nor in line with other QPA layers (e.g. XCB). Changing the Android QPA implementation is complex and a short term fix is necessary. This patch removes the member m_backingStoreSet. Instead of it, QAndroidPlatformBackingStore::flush() directly checks, if the platform window corresponding to the QWindow argument is associated to a backing store. If that is not the case, setBackingStore() is called. QTBUG-97482 has been fixed with another approach, which this patch reverts. The following commits are effectively reverted by this patch: 9a39ad8dfb4e6d1a179bd0fa38026886f8f7cb8e f91588923b1e7b68f1bd79b38af44d024df85996 a4ca9e80658bca7dad1529f03c1b59173a6ecf62 dbb072eb2838a04e89e34dad686394a496d5de87 959a8b3967ac3b6315f5b458628ec5661dfc367e Fixes: QTBUG-97482 Pick-to: 6.6 6.5 6.2 Change-Id: Ic4344f8df2e954c057dd2705340f11dfd2d4c6fe Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io>
* Implement virtual void QPlatformWindow::setBackingStore()Axel Spoerl2023-07-143-2/+11
| | | | | | | | | | | | | | | | | | QWidget re-uses an existing backing store. Platform windows depend on being associated to a backing store, in case they become toplevel windows. If a platform window gets deleted and re-created each time it is shown or hidden, it has to be manually associated to the re-used backing store. This patch partly reverts fbf0aeea7d3b38ced7a16fcd5c3e2e9b45536292. It removes Android specific code from QWidgetPrivate::create(), which has been added to suppress re-using backing stores in the absence of the new API.

* | Make QWindow's windowState a QFlags of the WindowStateOlivier Goffart2017-03-162-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | This reflects QWidget API, and restores some behavior from Qt4. Some WM can have several state at the same time. On Plasma for example, when a window is both maximized and minimized, the "maximized" checkbox is checked from the taskbar entry. The API of QPlatformWindow was changed to take a QFlag and the platform plugins were adapted. - On XCB: Always send the full state to the WM. And read the full state. - On Windows: The code was originally written with '&' in Qt4, and was changed to == when porting. Some adaptation had to be made so the states would be preserved. - On macOS: Only a single state can be set and is reported back for now, with the possibly to expand this in the future. - Other platforms: Just do as before with the effective state.

* linuxfb: add experimental support for DRM dumb buffersLaszlo Agocs2016-11-242-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a QFbScreen implementation that uses DRM dumb buffers and page flipping, thus implementing a vsynced, double (triple) buffered plain software platform plugin. Besides better supporting systems that by now only do fbdev via (possibly buggy) emulation, this can also be an enabler for implementing certain types of 2D accelerated compositors e.g. for Wayland. Enable with QT_QPA_FB_DRM=1. Right now there is no good way to autodetect the support for dumb buffers early enough so the default is always the traditional fbdev path. Long-term this will also enable proper multi-display support like with eglfs' DRM backends. Multiple QScreens are not yet reported currently due to the single-screen limitations of fbconvenience. The generic DRM code is shared with eglfs, meaning configuration happens via the JSON file specified in QT_QPA_(EGLFS_)KMS_CONFIG. This allows changing the screen resolution, disabling outputs, etc. [ChangeLog][Platform Specific Changes][linuxfb] Added experimental support for DRM dumb buffers. Enable by setting the environment variable QT_QPA_FB_DRM to 1. Task-number: QTBUG-56306 Change-Id: I4bdcf16fff67412183220dffa0c4ea235c5cad3d Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* linuxfb: Make first window fullscreen like eglfsLaszlo Agocs2016-11-093-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...unless the legacy behavior is requested via QT_QPA_FB_FORCE_FULLSCREEN=0 or the platform plugin overrides QFbScreen::flags() to return QFbScreen::DontForceFirstWindowToFullScreen. The long pending asymmetry between eglfs and linuxfb is going to end because with the increased focus on the integrated Qt Quick Software backend the expectation for launching apps with -platform linuxfb is to behave in the normal, eglfs style, embedded manner. Forcing every app to handle this manually in QML is silly. Widget applications also benefit since the old non-fullscreen main window approach is pretty much never what is wanted (considering there is no desktop and the content in the background is either garbage or whatever was on the terminal). However, not every fbconvenience-based platform wants this. For example, vnc should remain with the old way where window sizes are not altered. vnc therefore opts out via QFbScreen::flags(). bsdfb follows the linuxfb behavior. [ChangeLog][Important Behavior Changes] The linuxfb and bsdfb platform plugins now follow the behavior of eglfs by making the first window fullscreen. This provides consistency and avoids applications having to make their windows match the screen size manually. The new behavior can be disabled by setting the environment variable QT_QPA_FB_FORCE_FULLSCREEN=0.
