Hi,

As there is a setDefaultButton in Shell/Decoration to handle ENTER on a
shell, there is a way to handle a ESC press to the whole shell too? I could
not find it anywhere.

Thanks,

Marcelo

AFAIK ESC can generate SWT.Traverse events. Added at the Shell level, a
TraverseListener could close the shell.

Is this what you are looking for?

Hi Paul,

I solved the issue adding a filter to the display:

display.addFilter(SWT.KeyDown, new Listener()
{
public void handleEvent(Event e)
{
switch (e.keyCode)
{
case SWT.ESC:
{
Display.getCurrent().getActiveShell().close();
}
break;
}
}
});

Thanks for your help anyway.

Regads,

Marcelo

This is definitely a hack and I would strongly recommend you look at the
TraverseListener solution that Paul offered. Display filters apply to
all windows and widgets and thus this kind of listener is dangerous - if
you don't remove it it will probably result in undesired behavior after
your dialog is closed.
