Examples of org.eclipse.swt.widgets.Control.toControl()

org.eclipse.swt.widgets.Control.toControl()
Returns a point which is the result of converting the argument, which is specified in display relative coordinates, to coordinates relative to the receiver.
@param x the x coordinate to be translated @param y the y coordinate to be translated @return the translated coordinates @exception SWTException
- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
@since 2.1

        // In order to know where to draw the string we have to calculate where the 
        // drop event has taken place with respect to the ViewportPane.
        // The Event returns the location but it is w.r.t the Display.
        // All SWT widgets have helper methods to determine this so:
        Control control=pane.getControl();
        final Point drawLocation = control.toControl(getEvent().x, getEvent().y);
        
        // By Adding a custom draw command we can draw on the viewport model... 
        pane.addDrawCommand(new AbstractDrawCommand(){
