Originally, having the drag source client in charge of cursor updates was simple enough, flexible and coherent with the prior art. Things accumulated over time that made it not such a great choice: - The tablet protocol sporting its own on-screen pointer cursors made clients need to be painfully aware of the device that started drag-and-drop, in order to modify the correct cursor, provide the correct serials, etc. - The shapes protocol greatly simplified the set of sensible cursors - On top of that, not every compositor nor toolkit library knows to do well all of that. Nowadays, it seems simpler to leave this bit of user feedback up to the compositor, as it will/should be aware of the device driving drag-and-drop, as well as the currently selected action. In order to allow for a seamless transition (mostly in the client side), document this as mandatory only if version 4 of the wl_data_* interfaces is implemented by the compositor. The version bump only identifies to clients the possibility to avoid doing any cursor feedback themselves. Signed-off-by: Carlos Garnacho <carlosg@gnome.org> |
