NAME
Gtk2::Gdk::ColormapDESCRIPTION
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

- ... (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.
