AutoWarnDlg

Self-terminating modal warning dialog with flashing icon

A warning dialog is displayed with a flashing exclamation mark. The dialog is
terminated automatically with the default reply, if the user does not press a
button in a specified period of time.
This can be useful e.g. for functions, which are checked with automated tests, because the dialog does not block the execution completely.
Example:
Show a warning for 15 seconds, choose 'Cancel' if time has passed:
Opt.Delay = 15;
Opt.Button = {'Cancel', 'Reject', 'Accept'}; % 1st is default
Opt.Interpreter = 'tex';
Opt.Wrap = false;
[Reply, TimeOut] = AutoWarnDlg({'This is a \bfwarning\rm!', 'Accept, reject or cancel?'}, 'Question', Opt)

Features: Move button focus with the keyboard, copy warning message to the clipboard, flashing icon, text wrapping can be controlled, works even when called from a callback with 'Interruptible' property set to 'off'.
