* xcb: Remove QXcbScreen::m_nativeGeometryAlexander Volkov2016-01-081-9/+4
| | | | | | | | | | | | It is equal to m_geometry since c173a5071906867de9da26ee8f49224b23c2ef1d (Remove QT_DEVICE_PIXEL_RATIO support from xcb). Also remove the declaration for QXcbWindow::screenForNativeGeometry(), which was forgotten to be removed in that commit.

* xcb: Use a placeholder QScreen when there are no outputs connectedBłażej Szczygieł2015-12-111-13/+36
| | | | | | | | | | | | | | | | | | | | | | If no screens are available, windows could disappear, could stop rendering graphics, or the application could crash. This is a real use case in several scenarios: with x11vnc, when all monitors are physically disconnected from a desktop machine, or in some cases even when the monitor sleeps. Now when the last screen is disconnected, it is transformed into a fake screen. When a physical screen appears, the fake QScreen is transformed into a representation of the physical screen. Every virtual desktop has its own fake screen, and primary screens must belong to the primary virtual desktop. It fixes updating screen geometry on temporarily disabled screens in the middle of the mode switch. Expected results: Windows don't disappear, the application doesn't crash, and QMenu is displayed on the appropriate screen. This reverts patch 51ada7734ad780178ecced11e0dff454dfc2e5f2 Change-Id: I6e8eb682b0c8425d08ffdaecbd4c6c7700c914b4 Task-number: QTBUG-42985 Reviewed-by: Shawn Rutledge <shawn.rutledge@theqtcompany.com>

* Keep screen geometries from overlappingPaul Olav Tvete2015-04-141-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | The simple mapping of dividing each position by the devicePixelRatio does not work when screens have different DPR. If the low-DPR screen above or to the left of the high-DPR screen, the geometries will overlap in the Qt coordinate system. This change introduces a new mapping where the origin of each screen does not move. This mapping is not perfect: it will have gaps between contiguous screens. However, it will keep non-overlapping screens non-overlapping in the Qt coordinate system. Since there is no longer a simple linear coordinate transform, we have to add screen-dependent mapping functions, and distinguish between local and non-local coordinates. A side benefit is that the code is now easier to read, since we remove most manual coordinate transformation. We also have to cache the screen of each window: since we send resize events before screen change events, we cannot rely on QPlatformWindow::screen() (which is set from the screen change event).

* Improve handling of XRandR events in XCB backendDaniel Vrátil2015-03-111-50/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | Querying X server for data can be very expensive, especially when there are multiple processes querying it at the same time (which is exactly what happens when screen configuration changes and all Qt applications receive XRandR change notifications). This patch is aiming to reduce the number of queries to X server as much as possible by making use of detailed information available in the RRCrtcChangeNotify and RROutputChangeNotify events. Firstly, the backend now does not rebuild all QXcbScreens on any change (which involved the very expensive xcb_randr_get_screen_resources() call), but only builds the full set of QXcbScreens once in initializeScreens(), and then just incrementally updates it. Secondly, it avoids querying X server for all screens geometry as much as possible, and only does so when CRTC/Output change notification for a particular screen is delivered. As a result, handling of all XRandR events on screen change is reduced from tens of seconds to less then a seconds and applications are better responsive after that, because we don't block the event loop for long. The X server is also more responsive after the screen change, since we are not overloading it with requests.

This overwrites any existing event mask already set and by that breaks applications when a new screen is added. By first fetching the existing event mask and adding it to the newly installed event mask, Qt does no longer break applications also installing an event mask on the root window.

* Update QScreen::availableGeometry() on _NET_WORKAREA atom changesMartin Klapetek2014-03-151-1/+2
| | | | | | | | | | | | | | When the window manager sets new workarea using the _NET_WORKAREA xcb atom, QScreen::availableGeometry() does not react to that and returns an invalid available geometry. This patch reacts to that change and updates the QScreen property properly on xcb platform.

* XCB: Don't recalculate the DPI if we have a forced DPI settingThiago Macieira2013-12-301-3/+3
| | | | | | | | | | | | | | | logicalDpi() already has the logic to check m_forcedDpi, so let's reuse it. I hope it's not a problem that we send a signal that it changed when nothing changed. [ChangeLog][Platform Specific Changes][X11 / XCB]Fixed a bug that caused Qt applications to think the screen DPI had changed when it had not, after connecting or disconnecting monitors.

* xcb: every window should have a title in debug modeShawn Rutledge2013-10-091-0/+12
| | | | | | | | | | | | Qt creates various invisible windows for internal purposes. Giving them all titles makes the output of tools like xprop and xwininfo more readable, which makes solving certain bugs (like transient-window bugs) easier.

* Move the X11 system tray code from widgets into XCB-plugin.Friedemann Kleint2013-07-301-0/+1
| | | | | | | | | | | | | | | | | | - Add system tray tracker class to XCB plugin and provide functionality via invokable slots of the native interface. - Remove XLib-dependency of widgets/utils. - Reintroduce tracking of tray window destruction and recreation, which was removed in the XLib-code when porting it from Qt 4 to Qt 5. This paves the way for implementing the tray icon completely in terms of QPlatformSystemTrayIcon at some point later.

| | | | | | | | | | | | | This allows you to easily retrieve properties in the XSETTINGS specification. It is also possible to add listeners to get notified when a specific property changes. XSETTINGS is lazy initialized, so it will not be instansiated before someone uses it.

| | | | | | | | | | | | | | | | | This functionality was in Qt4's qapplication_x11.cpp and was missing from the XCB QPA plugin. Ported the code from xlib to xcb. This code was actually tested (with plasma), unlike the Qt-4.8 code which skipped every other character... for (uint i = 0; i < 20 && i + sent <= length; i++) xevent.xclient.data.b[i] = message[i + sent++]; Provide a QPA native-function for accessing the startup id, for cases where an application doesn't show a window, but starts another app instead, or asks a running app to show the window on its behalf.
