Sommaire

NAME

Gtk2::GC

DESCRIPTION

These functions provide access to a shared pool of Gtk2::Gdk::GC objects. When a new Gtk2::Gdk::GC is needed, Gtk2::Gdk::GC::get is called with the required depth, colormap and Gtk2::Gdk::GCValues. If a Gtk2::Gdk::GC with the required properties already exists then that is returned. If not, a new Gtk2::Gdk::GC is created.

METHODS

gc = Gtk2::GC->get ($depth, $colormap, $values)

*
$depth (integer)
*
$colormap (Gtk2::Gdk::Colormap)
*
$values (Gtk2::Gdk::GCValues) Values to match

$values is a hashref with keys and values as per "Gtk2::Gdk::GC->new" (see Gtk2::Gdk::GC).

Compatibility

Before version 1.200 of the Gtk2 perl module, it was necessary to call "Gtk2::GC::release()" on GCs obtained from "Gtk2::GC::get()". As of version 1.200, this is no longer necessary; a GC will be released when the last perl reference goes away. Old-style code continues to work, but "Gtk2::GC::release()" is deprecated.
