Tk::Role::HasWidgets(3User Contributed Perl DocumentatiTk::Role::HasWidgets(3)

NAME
       Tk::Role::HasWidgets - keep track of your tk widgets

VERSION
       version 1.112380

SYNOPSIS
	   package Your::Tk::Window::Class;

	   use Moose;
	   with	'Tk::Role::HasWidgets';

	   # store a button
	   $self->_set_w( my_button => $button );

	   # later on, in one of the methods
	   $self->_w( 'my_button' )->configure(	... );

	   # when no longer needed:
	   $self->_del_w( 'my_button' );

DESCRIPTION
       When programming	Tk, it's almost	always a good idea to keep a reference
       to the widgets that you created in the interface. Most of the time, a
       simple hash is enough; but it is	usually	wrapped	up in methods to make
       the hash	private	to the window object. And of course, those methods are
       duplicated in all modules, under	a form or another.

       Since duplication is bad, this module implements	a Moose	role
       implementing those methods once and forever. This implies that your
       class is	using Moose in order to	consume	the role.

   About the method names
       The methods featured in this role begin with "_", that is, they are
       following Perl convention of private methods. This is on	purpose:
       remember	that this method is a role, consumed by	your class. And	you
       don't want those	methods	to be available	outside	of the window class,
       do you?

METHODS
   _set_w
	   $object->_set_w( $name, $widget );

       Store a reference to $widget and	associate it to	$name.

   _w
	   my $widget =	$object->_w( $name );

       Get back	the $widget reference associated to $name.

   _del_w
	   $object->_del_w( $name );

       Delete the $name	reference to a widget.

   _clear_w
       Empty the widget	references.
