gtk2::gdk::colormap(3) [suse man page]

Gtk2::Gdk::Colormap(3)					User Contributed Perl Documentation				    Gtk2::Gdk::Colormap(3)

NAME

       Gtk2::Gdk::Colormap

DESCRIPTION

       Colormaps are used to store the mappings between the RGB values you ask for and the actual, hardware-dependent values used to display those
       colors.	The "$colormap->alloc_color" and "$colormap->alloc_colors" methods do the necessary work to allocate a color within the visual;
       this actually has nothing to do with memory management, so it is important that you call "$colormap->free_colors" to release those spots in
       the colormap allocated by "alloc_color" and "alloc_colors".

HIERARCHY

	 +----Gtk2::Gdk::Colormap

METHODS

   colormap = Gtk2::Gdk::Colormap->new ($visual, $allocate)
       o   $visual (Gtk2::Gdk::Visual)

       o   $allocate (boolean)

   boolean = $colormap->alloc_color ($color, $writeable, $best_match)
       o   $color (Gtk2::Gdk::Color)

       o   $writeable (boolean)

       o   $best_match (boolean)

   list = $colormap->alloc_colors ($writeable, $best_match, ...)
       o   $writeable (boolean)

       o   $best_match (boolean)

       o   ... (list) of Gtk2::Gdk::Color's to be allocated

       Returns a list of boolean values, telling whether the color at the corresponding spot in ... could be allocated.

   $colormap->free_colors (...)
       o   ... (list) of Gtk2::Gdk::Color's to be freed

   color = $colormap->query_color ($pixel)
       o   $pixel (unsigned)

   $colormap->rgb_find_color ($color)
       o   $color (Gtk2::Gdk::Color)

   screen = $cmap->get_screen
       Since: gtk+ 2.2

   colormap = Gtk2::Gdk::Colormap->get_system
   visual = $colormap->get_visual

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.

       [From: http://developer.gnome.org/doc/API/2.0/gtk/gtk-Graphics-Contexts.html <http://developer.gnome.org/doc/API/2.0/gtk/gtk-Graphics-
       Contexts.html>]

HIERARCHY

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

METHODS

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

       o   $colormap (Gtk2::Gdk::Colormap)

       o   $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.
