screenToWindow

screenToWindow(x: Real io;
               y: Real io);

The method in the following example shows the use of the screenToWindow method.

vars
    x, y : Real;
begin
    cntrl.windowToScreen(x, y);       // Convert 0, 0 to screen coordinates.
    cntrl.form.screenToWindow(x, y);  // x, y now positioned within the
                                      // form of the control.
end;
