Dispose of SWT shell when cursor moves out of it

Question

Hi!

I'm implementing a custom preview/tooltip for an Eclipse plug-in. It did it using a Shell in SWT, removing all its trimmings and placing a text box inside it. It looks great. However now I need to dispose of the shell when the cursor moves out of the shell window and I ran into some issues:

Does it make sense to attach a mousemoveListener to the shell? First I was doing this but then I realized that this listener only captures mouse move Events which occur inside the shell. How will I capture the mouse going out of the shell so as I could dispose of it?

Thanks and regards, Krt_Malta

Answer 1

Attach a MouseTrackListener with MouseTrackAdapter as a listener and override mouseExit() method.

Answer 2

It allows me to attach it fine ok. But no events are generated so it's not disposed. This is how I am doing it:

final Shell popup = new Shell(PlatformUI.getWorkbench().getDisplay(), SWT.TOOL); 

    popup.addMouseTrackListener(new MouseTrackListener() { 
    public void mouseHover(MouseEvent e) { 
    } 
    public void mouseExit(MouseEvent e) { 
         popup.dispose(); 
    }
    public void mouseEnter(MouseEvent e) { 
    } 
    }); 

Why isn't it working? Thanks and regards, Krt_Malta
