I have an SWT standalone application that invokes various wizards and
inputdialogs. I want the user to be able to exit the application while any
of these dialogs are presented and have them close automatically. I would
think that the following code would work, but I keep getting the notorious
"Widget is disposed Exception" being thrown.
exitMenu.addSelectionListener(new SelectionListener()
{
public void widgetSelected(SelectionEvent e)
{
Shell shells[] = getShell().getShells();
for ( int i = 0; i < shells.length; i++ )
{
shells[i].close();
shells[i].dispose();
}
shell.close();
dispose(); // <= "Widget is disposed Exception" being thrown
here...
}
});
Now, if I call shell.getShells( ) again before I attempt to dispose the
parent shell it returns an empty array. I'm probably missing something here
but I'm not sure what. Any help is greatly appreciated!
Many thanks!

D'oh, this is what I get for working at 2am on a Saturday.
shell.close();
shell.dispose(); // <= Forgot the shell part...
Sorry for the trouble.
