Hi,

I have a class that has the below open() method. This class does NOT
inherit any GUI class. How would I catch the close event when the user
click the 'X' at the top-right corner of the window? (I am using SWT on
WINDOWS XP.) Thanks!

public void open()
{
m_display = Display.getDefault();
createContents();
m_shell.layout();
m_shell.open();
while (!m_shell.isDisposed())
{
if (!m_display.readAndDispatch())
m_display.sleep();
}

}

Use:

m_display.addListener(SWT.Close, yourListener);

Thanks for pointing me to the right direction...It was more of the below...

m_shell.addShellListener(new ShellAdapter()
{
public void shellClosed(ShellEvent e)
{
dispose();
}
});
