NAME ^

App::Chart::Gtk2::Ex::TreePath::Subclass -- TreePath constructors with reblessing

SYNOPSIS ^

 package My::TreePath::Variant;
 use App::Chart::Gtk2::Ex::TreePath::Subclass;
 our @ISA = ('App::Chart::Gtk2::Ex::TreePath::Subclass', 'Gtk2::TreePath');
 # ...

 package main;
 my $path = My::TreePath::Variant->new;

DESCRIPTION ^

App::Chart::Gtk2::Ex::TreePath::Subclass helps making Perl subclasses of Gtk2::TreePath. It provides versions of the following Gtk2::TreePath constructors

    new()
    new_first()
    new_from_indices()
    new_from_string()

They're designed as a multi-inheritance mix-in to override the corresponding base methods in Gtk2::TreePath. They re-bless the created object into the class name given in the call, which is what you want when subclassing, and which the Gtk2::TreePath functions don't do (as of Gtk2-Perl version 1.223).

Note that such re-blessing is only a Perl level subclass and so won't be seen if the path object is returned back from some Gtk function, they'll give back only plain Gtk2::TreePath.
