Bug 312642

Description Misha Koshelev 2010-05-12 11:05:22 EDT

Build Identifier: SWT 3.5.2 running outside Eclipse

Dear All:

I am using:
swt-3.5.2-gtk-linux-x86_64.jar (Firefox 3.0)
swt-3.5.2-win32-win32-x86.jar (IE 7? on Windows XP 64-bit)

On both, I am unable to get any events with VisibilityWindowListener. For example, the example found here:
http://www.java2s.com/Tutorial/Java/0280__SWT/AddingVisibilityWindowListener.htm
never calls the visibility listeners.

I have gotten around this by using the SWT.Show and SWT.Hide listeners for the parent shell as shown in following code snippet. Please correct me if I am missing something simple, but it seems per instructions I _should_ get notified or visibility changes (e.g., shell.open()) and I do _not_.

Thank you
Misha

	browser.addVisibilityWindowListener(new VisibilityWindowListener() {
		public void hide(WindowEvent event) {
		    debug("VisibilityWindowListener.hide: "+event);
		    setVisible(false);
		    synchronized(driver) {
			driver.notifyAll();
		    }
		} 
		public void show(WindowEvent event) {
		    debug("VisibilityWindowListener.show: "+event);
		    setVisible(true);
		    synchronized(driver) {
			driver.notifyAll();
		    }
		} 
	    });
	browser.getShell().addListener(SWT.Hide,new Listener() {
		public void handleEvent(Event event) {
		    debug("SWT.Hide,Listener.handleEvent: "+event);
		    setVisible(false);
		    synchronized(driver) {
			driver.notifyAll();
		    }
		}
	    });
	browser.getShell().addListener(SWT.Show,new Listener() {
		public void handleEvent(Event event) {
		    debug("SWT.Show,Listener.handleEvent: "+event);
		    setVisible(true);
		    synchronized(driver) {
			driver.notifyAll();
		    }
		}
	    });

Reproducible: Always
