=for position DESCRIPTION

=head1 DESCRIPTION


Gtk2::MessageDialog is a dialog with an image representing the type of message
(Error, Question, etc.) alongside some message text.  It's simply a convenience
widget; you could construct the equivalent of Gtk2::MessageDialog from Gtk2::Dialog
without too much effort, but Gtk2::MessageDialog saves typing and helps create a
consistent look and feel for your application.

The easiest way to do a modal message dialog is to use C<< $dialog->run >>, which
automatically makes your dialog modal and waits for the user to respond to it.
You can also pass in the GTK_DIALOG_MODAL flag when creating the MessageDialog.
