qml: fix drag item no longer showing any image regression
Since 72f086c9, RoundImage
has been used in DragItem
.
However, it only works asynchronously and by the time
the input items are resolved, RoundImage
instance(s)
are still in the progress of loading the image.
I added an intermediate state to wait for images to be loaded. If the loading takes too much time, then the timer is going to start the drag, so this change does not make drag initalization synchronous.
Regression since !5826 (merged).
Request review @chub.
