Hi,
I am working on a GUI application and I use SWT.

I wonder how I can quit this application by clicking a button in the toolbar just like closing it by pressing the x sign on the corner of the window.

This is the code that creates the quit icon :

       
CustomToolbar custToolBar33333 = new CustomToolbar(compTB3, SWT.FLAT, "Next Actions");      
    
        item33333333 = new ToolItem(custToolBar33333.getToolBar(), SWT.PUSH);
        item33333333.setImage(image_exit); item33333333.setText("Quit"); item33333333.setToolTipText("Quit the tool");
        item3333333.addListener(SWT.Selection, toolBarListener);

Open in new window

in listener class add this code for this item:

try {
  if (!shell.isDisposed()) {
    shell.close();
    shell.dispose();
  }
} finally {
  display.dispose();
}

also you have to change "setShell" method in this way:

public void setShell(Shell shell, Display display) {
  this.shell = shell; this.display = display;
}

and to add reference to Display as a member of this class.
