DragDrop Event 11
Description
If enabled, this event is reported when the user drops one object (the dragged object) onto another (the target object). The event is generated by the target object, that is, the object which is being dropped on.
The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 7-element vector as follows :
[1] |
Target Object | ref or character vector |
[2] |
Event | 'DragDrop' or 11 |
[3] |
Dragged Object | ref or character vector |
[4] |
Y | y-position of mouse pointer in the target object |
[5] |
X | x-position of mouse pointer in the target object |
[6] |
H | height of dragged object in the coordinate system of the target object |
[7] |
W | width of dragged object in the coordinate system of the target object |
[8] |
Shift State | numeric scalar containing the sum of the values associated with the Shift(1), Ctrl(2) and Alt(4) keys when the object was dropped. |
Note that Y, H, X and W are all reported relative to the target object.
