* Only consider QScreen virtual siblings that have been addedTor Arne Vestbø2023-05-311-2/+5
| | | | | | | | | | | | | | | | | If a platform builds up a list of QPlatformScreens, and then adds them incrementally, while at the same time implementing virtualSiblings in QPlatformScreen to return the full list of screens, the virtual sibling QScreens will contain nullptrs for each non-added screen. It could be argued that this is the fault of the platform plugin, since it's reporting a virtual sibling that it hasn't added yet, but we can easily work around it in QScreen as well.

* Let QScreen::grabWindow's winId parameter default to 0 and add testVolker Hilsheimer2020-07-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The platform plugins are implemented to grab the entire screen if no window ID is provided. They do not grab the entire virtual screen, just the screen the method is called on. On macOS, the implementation ignored the window parameter, and always grabbed the entire virtual screen. This change fixes the cocoa implementation. The test passes in local tests (with two displays with different dpr). Since grabbing a screen returns an image with managed colors, we need to convert it to sRGB color spec first, otherwise displaying a grabbed image will produce different results. This will need to be changed once Qt supports a fully color managed flow. The test does not cover the case where a window spans multiple displays, since this is generally not supported at least on macOS. The code that exists in QCocoaScreen to handle that case is untested, but with the exception of the optimization it is also unchanged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On X11, QScreen::availableGeometry() is broken with multi-head systems, and there doesn't seem to be a real fix for this due to limitation in the protocol and therefore support in WMs (more details in the patch). In Gnome this issue is more visible because on this DE the _NET_WORKAREA rectangle represents the intersection of the available geometries on all monitors. This results in a big area of "dead space" on the secondary screen, when primary screen is positioned lower in the virtual space. If menu is opened by clicking in this dead space, the menu is awfully misplaced (qmenu uses availableGeometry() to calculate the position of menu). On Ubuntu with Unity (same is true for KDE Neon+Kwin and LUbuntu+Openbox), _NET_WORKAREA returns a bounding rectangle containing all monitors. Which does not cause the menu misplacement as "dead space" is outside clickable area. But this does not mean that the QScreen::availableGeometry() reported values are correct. With the same setup as described above, QScreen::availableGeometry() thinks that we have a tool panel on the right screen, when in reality it is on the left screen. AwesomeWM for example does not set _NET_WORKAREA at all, which means QScreen::availableGeometry() == QScreen::geometry(). I am not aware that it would cause any issues for popup/menu window positioning in Qt (Qt positions these windows manually by bypassing WM (via Qt::BypassWindowManagerHint) and using availableGeometry for calculations. With this patch, we would take the same code path as if _NET_WORKAREA was not set (where we know that_NET_WORKAREA is cleary wrong). The solution here is to recognize _NET_WORKAREA as true available geometry only in specific cases (cases where the meaning is cleary defined by the specification) and adjust the documentation accordingly. Not knowing the true available geometry on X11 is mitigated by WMs. Window manager can position windows as it wants. WMs are smart enough not to place windows on top of reserved areas at edges (even if user has explicitly requested this via setGeometry based on inaccurate information from availableGeometry()). [ChangeLog][Platform Specific Changes][Linux] The _NET_WORKAREA atom is used for calculating QScreen::availableGeometry() only on systems with one monitor. In all other cases QScreen::availableGeometry() is equal to QScreen::geometry(). To restore the legacy behavior with untrustworthy values in QScreen::availableGeometry() set QT_RELY_ON_NET_WORKAREA_ATOM=1 environment variable.

* Add screen product informationPier Luigi Fiorini2017-01-161-0/+36
| | | | | | | | | | | | | | | | | | | | | Add new methods to QPlatformScreen that platform plugins can reimplement in order to provide more information such as vendor, model and serial number. Expose that information as QScreen properties. A use-case for this feature is a Wayland compositor that maps screens to Wayland outputs hence it needs to replicate the information. This information can also be added to the diagnostic output of qtdiag. [ChangeLog][QtGui][QScreen] Add manufacturer, model and serialNumber properties.
