[xwl] Generic X selections translation mechanism with Clipboard support Summary: In this patch an infrastructure is created to represent generic X selections in a Wayland session and use them for data transfers between Xwayland windows and Wayland native clients. The central manager is the DataBridge class, in which Selection objects can be created. This is hard-coded and such a Selection object persists until the end of the session, so no arbitrary selections can be created on the fly. For now the X Clipboard selection is supported, whose corresponding mechanism in the Wayland protocol is just called Selection. A Selection object listens for selection owner changes on the X side and for similar events into the Wayland server interfaces. If a data provider is available a selection source object is created by the Selection object. In case data is requested on the other side, a data transfer is initialized by creating a Transfer object. A Selection keeps track of all transfers and makes sure that they are destroyed when they are finished or in case they idle because of misbehaving clients. The Clipboard class translates the X Clipboard via a proxy window. Selection changes on the Wayland side are listened to through a new signal on the active KWayland seat interface. The previously used X clipboard syncer helper is disabled. The clipboard sync autotest is changed to the new mechanism. BUG: 394765 BUG: 395313 Test Plan: Manually and clipboard sync autotest.

[xwl] Drag and drop between Xwayland and Wayland native clients Summary: Building upon the generic X Selection support this patch establishes another selection class representing the XDND selection and provides interfaces to communicate drags originating from Xwayland windows to the Wayland server KWin and drags originating from Wayland native drags to Xwayland. For Wayland native drags KWin will claim the XDND selection as owner and will simply translate all relevant events to the XDND protocol and receive alike messages by X clients. When an X client claims the XDND selection KWin is notified via the X protocol and it decides if it allows the X drag to transcend into the Wayland protocol. If this is the case the mouse position is tracked and on entering a Wayland native window a proxy X Window is mapped to the top of the window stack. This proxy window acts as a drag destination for the drag origin window and again X messages will be translated into respective Wayland protocol calls. If the cursor leaves the Wayland window geometry before a drop is registered, the proxy window is unmapped, what triggers a subsequent drag leave event. In both directions the necessary core integration is minimal. There is a single call to be done in the drag and drop event filter through the Xwayland interface class. From my tests this patch facilitates drags between any Qt/KDE apps. What needs extra care are the browsers, which use target formats, that are not directly compatible with the Wayland protocol's MIME representation. For Chromium an additional integration step must be done in order to provide it with a net window stack containing the proxy window. Test Plan: Manually. Auto tests planned.

Q_DISABLE_COPY(Selection)
[xwl] Generic X selections translation mechanism with Clipboard support Summary: In this patch an infrastructure is created to represent generic X selections in a Wayland session and use them for data transfers between Xwayland windows and Wayland native clients. The central manager is the DataBridge class, in which Selection objects can be created. This is hard-coded and such a Selection object persists until the end of the session, so no arbitrary selections can be created on the fly. For now the X Clipboard selection is supported, whose corresponding mechanism in the Wayland protocol is just called Selection. A Selection object listens for selection owner changes on the X side and for similar events into the Wayland server interfaces. If a data provider is available a selection source object is created by the Selection object. In case data is requested on the other side, a data transfer is initialized by creating a Transfer object. A Selection keeps track of all transfers and makes sure that they are destroyed when they are finished or in case they idle because of misbehaving clients. The Clipboard class translates the X Clipboard via a proxy window. Selection changes on the Wayland side are listened to through a new signal on the active KWayland seat interface. The previously used X clipboard syncer helper is disabled. The clipboard sync autotest is changed to the new mechanism. BUG: 394765 BUG: 395313 Test Plan: Manually and clipboard sync autotest.
