=head1 NAME

messageBox  -  pop up a message window and wait for user response.

=head1 SYNOPSIS

S<    >I<$response> = I<$widget>-E<gt>B<messageBox>(I<-option> =E<gt> I<value>, ... );

=head1 DESCRIPTION

This method uses L<Tk::Dialog|Tk::Dialog> to quickly create several common dialog boxes.
A dialog widget consists of a message, an icon and a set of buttons (see
the I<-type> option).  After the message window is popped up,  B<messageBox>
waits  for the user to select one of the buttons and return the button text.
NOTE:  unlike B<Tk::Dialog> which creates its widget once and can be used
many times, the B<messageBox> window is created every time it's used.

The following option/value pairs are supported:

=over 4

=item B<-default>

The case-sensitive symbolic name of the default button
for this message window  ('OK',  'Cancel'  and  so
on).  See  B<-type>  for a list of the symbolic names.
If the message box has  just  one  button  it  will
automatically  be  made  the  default, otherwise if
this option is not specified, there  won't  be  any
default button.

=item B<-icon>

Specifies an icon to display. Any of the builtin Tk bitmaps can
specified.

=item B<-message>

Specifies the message to display.

=item B<-title>

Specifies  a  string to display as the title.

=item B<-type>

Specifies a predefined set of buttons to be displayed. The following values are possible:
'AbortRetryIgnore', 'OK', 'OKCancel', 'RetryCancel', 'YesNo' or 'YesNoCancel'.
