=head1 NAME

Curses::Toolkit::Widget::GenericButton - a button widget that can hold any other widget

=head1 VERSION

version 0.207

=head1 DESCRIPTION

The Curses::Toolkit::Widget::GenericButton widget is generally used to attach a
function that is called when the button is pressed.

This widget can hold any valid child widget. That is it can hold most any other
standard Widget. The most commonly used child is the
Curses::Toolkit::Widget::Label. This widget consists of a border, and a child
widget in that border.

However, if all you need is a simple text button, I recommend you use
L<Curses::Toolkit::Widget::Button>, it can take less space on the screen ( it
can have no border ), and has more theme properties that suites best text
buttons.

This widget can contain 0 or 1 other widget.
