In order to keep things simple, weston-dnd made a few choices that
turn out to be unrealistic, a few tweaks have been done to make it
less of a playground demo:
- It now caters for copy/move operations, instead of just move,
which still remains the default nonetheless.
- As "move" operations are no longer assumed, the item isn't removed
on start_drag, instead it is made translucent until the drag
operation finishes (and we know whether the item is to be
removed after transfer or left as is)
- For the same reasons, "Drop nowhere to delete item" no longer
happens. Drag-and-drop is a failable operation and must not result
in data loss.
- As multiple actions are now allowed, we set the pointer icon
surface accordingly to the current operation.
This makes weston-dnd a better example of what applications usually
want to do here.
Changes since v2:
- Updated to behave alright-ish with version < 3.
Changes since v1:
- Remove unneeded include. Remove extra newlines. Other minor
code fixes.
