Supported for all project types and targets.
Supported for all project types and targets.
The mouse button was pressed inside the control's region at the location passed in to x, y.
Notes
The coordinates x and y are local to the control, i.e. they represent the position of the mouse click relative to the upper-left corner or the Control.
Return True if you are going to handle the MouseDown. In such a case:
- The Action event, if any, will not execute and the state of the object will not change.
- You will receive the MouseDrag and MouseUp events.
If you return False, the system handles the MouseDown so the above event handlers do not get called.

Sample Code
The MouseDown event uses the DragItem constructor when the user drags the contents of the control. It is:
Var d As DragItem
d = New DragItem(Self, Me.Left, Me.Top, Me.Width, Me.Height)
d.Picture = Me.Image
d.Drag // Allow the drag
d = New DragItem(Self, Me.Left, Me.Top, Me.Width, Me.Height)
d.Picture = Me.Image
d.Drag // Allow the drag
