Sets the Exit button in dialog. The Exit button is commonly found in multi-page dialogs, where the user is given the option to exit the sequence at any point (as well as navigate through the sequence using Next and Back buttons).

define variable *dialog* = make(<dialog-frame>, exit-button?: #t, cancel-button?: #t, help-callback: method (gadget) notify-user (format-to-string ("Here is some help", gadget)) end);
dialog-exit-button-setter (make(<push-button>, label: "Yes", activate-callback: exit-dialog, max-width: $fill), *dialog*);
start-frame(*dialog*);
