# Gtk2::GC(3pm)

## 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.

## HIERARCHY

```
  Glib::Object
  +----Gtk2::Gdk::GC
       +----Gtk2::GC
```

## 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.
