From 8932576bbe04215139ed8d58d3711024189b0b34 Mon Sep 17 00:00:00 2001 From: David Redondo Date: Wed, 31 Jan 2024 12:06:16 +0100 Subject: client: Switch qt-toplevel-drag to xdg-toplevel-drag While no released compositor implemented qt-toplevel-drag it was a valuable to step to prove the protocol and the Qt implementation together with development pre-release versions of KWin. Now that the protocol is standardized we can switch to that version which is functionally identical.

This allows having detachable parts of a window + that when dragged out of it become a new window and can be dragged over + an existing window to be reattached. + + A typical workflow would be when the user starts dragging on top of a + detachable part of a window, the client would create a wl_data_source and + a xdg_toplevel_drag_v1 object and start the drag as normal via + wl_data_device.start_drag. Once the client determines that the detachable + window contents should be detached from the originating window, it creates + a new xdg_toplevel with these contents and issues a + xdg_toplevel_drag_v1.attach request before mapping it. From now on the new + window is moved by the compositor during the drag as if the client called + xdg_toplevel.move. + + Dragging an existing window is similar. The client creates a + xdg_toplevel_drag_v1 object and attaches the existing toplevel before + starting the drag. + + Clients use the existing drag and drop mechanism to detect when a window + can be docked or undocked. If the client wants to snap a window into a + parent window it should delete or unmap the dragged top-level. If the + contents should be detached again it attaches a new toplevel as described + above. If a drag operation is cancelled without being dropped, clients + should revert to the previous state, deleting any newly created windows + as appropriate. When a drag operation ends as indicated by + wl_data_source.dnd_drop_performed the dragged toplevel window's final + position is determined as if a xdg_toplevel_move operation ended. + + Warning!
