- point
- A System.Drawing.Point indicating the position at which the mouse was clicked, in screen coordinates.
true if a click at the specified point is to be handled by the control; otherwise, false.
The ControlDesigner.GetHitTest(System.Drawing.Point) method determines whether a click at the specified point should be passed to the control, while the control is in design mode. You can override and implement this method to enable your control to receive clicks in the design-time environment.
You can pass a point in screen coordinates to the System.Windows.Forms.Control.PointToClient(System.Drawing.Point) method of the System.Windows.Forms.Control class to obtain the coordinates of the point relative to the upper-left corner of the control.
The ControlDesigner.GetHitTest(System.Drawing.Point) method is called in response to the WM_NCHITTEST message, so it is called on each mouse move.
