RE: [platform-swt-dev] mouse wheel 
Thanks for the help.
I have try to use the scrollbar in a Canvas and add the SelectionListener to the scrollbars ( see the code below ).
I only obtained an anwser of the scroolbar listener when I clicked the left and right mouse buttons on it but nothing when i clicked or moved the mouse wheel.
¿Any idea to obtain an anwser of the mouse wheel?
Thank you in advance.

Rafael.

    a_Canvas = new Canvas(panel, 0x140b00);	// scroll
    a_Canvas.getHorizontalBar().setVisible(true);
    a_Canvas.getVerticalBar().setVisible(true);
    
    ScrollBar scrollHor = a_Canvas.getHorizontalBar();
    ScrollBar scrollVer = a_Canvas.getVerticalBar();
    scrollVer.addSelectionListener( 
                    new SelectionListener()
                        {
                        public void widgetSelected( SelectionEvent evt) 
                                        {
                                        System.out.println("  ****  VERTICAL SCROLLBAR WIDGETS_SELECTED");
                                        }
                        public void widgetDefaultSelected( SelectionEvent evt)
                                        {
                                        System.out.println("  **** VERTICAL SCROLLBAR WIDGETS_DEFAULT SELECTED");                            
                                        }
                        }
              );

SWT has no mouse wheel specific events.  The mousewheel events are 
translated into scrolling events in the operating system and reported by 
SWT as scrolling events in the SrollBars.  See 
ScrollBar.addSelectionListener.
