NAME

Tk::Derived - Base class for widgets derived from others

SYNOPSIS

  package Tk::Whatever;
  require Tk::Something; 
  require Tk::Derived;
  @ISA = qw(Tk::Derived Tk::Something);

  sub Populate
  {
   my ($cw,$args) = @_;
   ...
   $cw->SUPER::Populate($args);
   $cw->ConfigSpecs(...);
   ...
  }

DESCRIPTION

Tk::Derived is used with perl5's multiple inheritance to override some methods normally inherited from Tk::Widget.

Tk::Derived should precede any Tk widgets in the class's @ISA.

Tk::Derived's main purpose is to apply wrappers to configure and cget methods of widgets to allow the derived widget to add to or modify behaviour of the configure options supported by the base widget.

The derived class should normally override the Populate method provided by Tk::Derived and call ConfigSpecs to declare configure options.

The public methods provided by Tk::Derived are as follows:

->ConfigSpecs(-key => [kind, name, Class, default], ...)

1 POD Error

The following errors were encountered while parsing the POD:
