[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.

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.

[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] 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.
