Hi all, Can I avoid dialog closing when ESC key is pressed ?
I'm using org.eclipse.swt.widgets.Dialog as parent class for my Dialogs
and in Login Dialog I would like to prevent dialog closing when user
press [ESC] key.
I've tryed to use a callback function in close() method but It doesn't
work, close() method is never called.
My LoginDialog is created without icons:
SWT.APPLICATION_MODAL + SWT.TITLE
Any idea ?
Thanks in advance.
Roberto

Hi Ralf, Thank you, It works fine creating a Shell without parent, But I
had to change my Dialog parent class because
org.eclipse.swt.widgets.Dialog doesn't allow null Shell in constructor.
In any case it was easy, I was already using my own DialogBase that
extended from org.eclipse.swt.widgets.Dialog and now It extends from
Object and implements all methods I need from Dialog RAP class.
Regards.
Roberto.
