view mde/gui/widget/miscContent.d @ 161:e3fe6acc16fb
Replaced WidgetManager's click and motion callbacks with a drag event system.
This is less flexible, but much closer to what is required (and is simpler and less open to bugs through unintended use).
The widget under the mouse is now passed (although could just as easily have been before).
