Placard.MouseDrag(x as Integer, y as Integer)

Supported for all project types and targets.

This event fires continuously after the mouse button was pressed inside the Placard. Mouse location is local to the control passed in to x, y.


This event will not occur unless you return True in the MouseDown event first.

The parameters x and y are local coordinates, i.e. they represent the position of the mouse relative to the upper-left corner of the Placard.

As this event is fired continuously (hundreds of time per second), it is your responsibility to determine if the mouse has really moved.
