Re: [platform-swt-dev] SWT shell and events

[Kurt Sultana <kurtanatlus@xxxxxxxxx>]

Here it is again since there was some formatting in the other code which may not display well:

 

popup = new Shell(PlatformUI.getWorkbench().getDisplay(), SWT.TOOL );
popup.setLayout(new FillLayout());
Text text = new Text(popup, SWT.MULTI | SWT.READ_ONLY | SWT.WRAP | SWT.V_SCROLL);
text.setBackground(new org.eclipse.swt.graphics.Color(PlatformUI.getWorkbench().getDisplay(), 255, 255, 204));
text.addMouseTrackListener(new MouseTrackListener() {
   public void mouseHover(MouseEvent e) {
   }   

   public void mouseExit(MouseEvent e) {
      popup.dispose();   

   }   

   public void mouseEnter(MouseEvent e) { 
   }

});

Hi, yes your are right. The problem isn't illustrated well in that code then I realized. My problem is this (I'm developing my own custom tooltip for an Eclipse plug-in):

 

I'm attaching a listener to a Text (which has a V_Scroll with it) which is inside a shell. The problem is that when I move the mouse over the vertical scrollbar the shell is disposed. I don't want that.

This is the code:

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


popup.setLayout(new FillLayout());


Text text = new Text(popup, SWT.MULTI | SWT.READ_ONLY | SWT.WRAP | SWT.V_SCROLL);


text.setBackground(new org.eclipse.swt.graphics.Color(PlatformUI.getWorkbench().getDisplay(), 255, 255, 204));


text.addMouseTrackListener(new MouseTrackListener() { 


   public void mouseHover(MouseEvent e) { 


   } 
   public void mouseExit(MouseEvent e) { 


      popup.dispose(); 
   } 
   public void mouseEnter(MouseEvent e) { 


   } 
}); 

How can I go about it?

 

Thanks and regards,

Regards
