=head1 NAME

Gtk2::Ex::Dialogs::Question - Provides a simple question dialog.

=head1 SYNOPSIS

 use Gtk2::Ex::Dialogs::Question ( destroy_with_parent => TRUE,
                                   modal => TRUE,
                                   no_separator => FALSE );

 # do some stuff like creating your app's main $window then,
 # to ensure that all messages use the right parent, set it:
 $Gtk2::Ex::Dialogs::Question::parent_window = $window;

 # now popup a new dialog
 my $r = ask Gtk2::Ex::Dialogs::Question ( "Is Perl only hacker's glue?" );
 if ( $r ) {
   # end-user thinks so
 } else {
   # end-user does not think so
 }

=head1 DESCRIPTION

This module provides a simple dialog api that wraps Gtk2::Dialog objectively.
The objective is a clean and simple question dialog (just "NO" and "YES"
buttons).

All public methods (and the entire class) support the following options:

=over

=item B<title> => STRING

The title of the dialog window. Defaults to an empty string.

=item B<text> => STRING

only mandatory argument.

=item B<icon> => /path/to/image || stock-id || Gtk2::Gdk::Pixbuf || Gtk2::Image

The dialog-sized image to place to the left of the text. Note: there are five
aliased stock-ids which correspond to the five gtk-dialog-* ids, "warning",
"question", "info", "error" and "authentication". Defaults to the stock-id
"gtk-dialog-question".

=item B<parent_window> => Gtk2::Window

Reference to the main application window.

=item B<destroy_with_parent> => BOOL

When the B<parent_window> is destroyed, what do we do? Defaults to FALSE.

=item B<modal> => BOOL

Does this message make the B<parent_window> freeze while the message exists.
Defaults to FALSE.

below. Defaults to FALSE.
