[platform-swt-dev] SWT shell and events

[Kurt Sultana <kurtanatlus@xxxxxxxxx>]

Hi!

I'm developing an Eclipse plug-in and I have a problem which is reproduced in this small SWT application:

public static void main(String[] args) { 
    Display display = new Display(); 
    Shell shell = new Shell(display); 
    Text text = new Text(shell, SWT.MULTI | SWT.WRAP | SWT.READ_ONLY | SWT.V_SCROLL); 
    text.setText("Hello"); 
    shell.setLayout(new FillLayout()); 
    shell.addMouseTrackListener(new MouseTrackListener() { 
 
      public void mouseEnter(MouseEvent arg0) { 
        System.out.println("mouseEnter"); 
 
      } 
 
      public void mouseExit(MouseEvent arg0) { 
        System.out.println("mouseExit"); 
 
      } 
 
      public void mouseHover(MouseEvent arg0) { 
        System.out.println("mouseHover"); 
 
      } 
    }); 
    // Display the window 
    shell.open(); 
    while (!shell.isDisposed()) { 
      if (!display.readAndDispatch()) { 
        display.sleep(); 
      } 
    } 
    display.dispose(); 
  }

As you can see I'm creating a shell and putting a Textbox inside it and putting it all across the shell. Then I attach a MouseTrackListener to the shell. The events don't fire (as in when I hover in the shell "mouseHover" is not printed etc). When I remove the Textbox the events fire. Can anyone tell me where the problem lies please? I don't want to attach a listener to the textbox but to the shell because if I attach it to the textbox, then the shell would dispose when I touch the scrollbar.

 

Thanks and regards,
