* xcb: convert last screen to fake when no screenLiang Qi2021-09-181-7/+29
| | | | | | | | | | | | | | | | | available for xrandr 1.5 like we did before for xrandr 1.4 (since a094af001795c9651b299d700a992150d1aba33a). Tested with following combination: * qtbase -DECM_ENABLE_SANITIZERS=address cmake build * examples/widgets/widgets/wiggly with ASAN_OPTIONS=verify_asan_link_order=0 env * xrandr --output LastScreen --off and --auto.

* xcb: support xrandr(1.5) monitor setupLiang Qi2021-09-011-106/+262
| | | | | | | | | | | | | | | | | | | | | | | | More information about monitor in xrandr 1.5, see https://keithp.com/blogs/MST-monitors/ Since this change, screen is logical instead of physical. If xrandr 1.5 and later is installed, Qt screen info will get from xrandr monitor object instead of xrandr output if only have 1.2 to 1.4. Users can manipulate monitor as they want, for example, a combination for two physical screens, half of one screen and etc. Didn't have chance to access MST monitors, but it should work if xrandr monitor object was created automatically. [ChangeLog][xcb] Qt screen info will get from xrandr monitor object if 1.5 is installed.

* Call updateHighDpiScaling() on screenAdded()Morten Johan Sørvig2021-04-281-1/+0
| | | | | | | | | | | | | | | | | | | | | | QHighDpiScaling has two init/update functions: - initHighDpiScaling(): called once during QGuiApplication construction - updateHighDpiScaling(): called whenever (relevant) screen configuration changes Currently the calls to updateHighDpiScaling() are made from multiple places including platform code. Simplify by calling it from two locations: - QWindowSystemInterface::handleScreenAdded() - QGuiApplicationPrivate::processScreenLogicalDotsPerInchChange() Replace comment about early calls to qt_defaultDpi with a test which calls qt_defaultDpiX/Y with no screens attached. (Looking at the qt_defaultDpiX() implementation, it is unlikely that there will be a problem as long as updateHighDpiScaling() is called before QGuiApplication::primaryScreen() starts returning a non-null value.)

| * Move screen maintenance functions from QPlatformIntegration to QWSITor Arne Vestbø2019-03-191-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QWindowSystemInterface is the de facto API for any plumbing going from the platform plugin to QtGui. Having the functions as protected members of QPlatformIntegration was idiosyncratic, and resulted in awkward workarounds to be able to call the functions from outside of the QPlatformIntegration subclass. The functions in QPlatformIntegration have been left in, but deprecated so that platform plugins outside of qtbase have a chance to move over to the new QWSI API before they are removed.

|/ | | | | | | | | | | The old name was confusing as it conflicted with QList<T>::swap(QList &other), that was doing something completely different.

| | | | | | | | | | | | | | This patch amends d67214302f269242ae3d8d2b962fd91ec42c979e. The issue was caused by mistakenly interchanging m_hasXRender <-> m_hasXRandr. Also renamed selectXRandrEvents() -> xrandrSelectEvents() to be more consistent with xi2Select*() API. And moved the xrandrSelectEvents() to QXcbConnection ctor for the same reason.
