- Event stream adaptations. When there is a toplevel-drag in place, do:
- Send wl_data_source.dnd_finished and end the session successfully
- Send wl_data_source.cancelled and end the MetaWindowDrag when ESC key
is pressed.
- Modify MetaWaylandDataDevice such that, when a toplevel-drag is
running, it does:
- Propagate motion events, so that they can be processed further by
MetaWindowDrag.
- Ends the associated MetaWindowDrag upon release event.
- Hook up the window mapping process in MetaWindowWayand, such that:
- the initial position of the window attached to the ongoing
toplevel-drag instance can be calculated and set.
- the appropriate gravity and flags can be set when calling MetaWindow's
meta_window_move_resize_internal, which allows it for example to be
moved freely (unconstrained) as per current dragging cursor.
Status:
- [x] Basic window drag triggering
- [x] Exclude the dragged window from event targets
- [x] Event forwarding (window drag vs wayland grabs)
- [x] Offset calc relative to toplevel geometry
- [x] Attach already mapped windows
- [x] Properly support not-yet-mapped windows
- [x] Disable visibility change animations
- [x] Dnd events stream adaptations
