Make the item as a drop destination
Source position: MUIClass.Area.pas line 145
published property TMUIArea.Dropable : Boolean |
Only objects with this attribute set to True will be asked if they want to become an active Drag'n'Drop destination at all. Though this attribute defaults to True, this doesn't mean that every object automatically acepts Drag'nDrop actions, because the DragQuery method is answered False when it arrives at area class.
