METHODS

13   gc = Gtk2::Gdk::GC->new ($drawable, $values=undef)
14           ·   $drawable (Gtk2::Gdk::Drawable)
15
16           ·   $values (scalar)
17
18           Create and return a new GC.
19
20           $drawable is used for the depth and the display
21           ("Gtk2::Gdk::Display") for the GC.  The GC can then be used with
22           any drawable of the same depth on that display.
23
24           $values is a hashref containing some of the following keys,

44
45           Keys not given get default values.  For the "foreground" and
46           "background" colour objects only the "pixel" field is used; the
47           red, green and blue are ignored.  For example
48
49               my $pixel = 0x123456;
50               my $color = Gtk2::Gdk::Color->new (0,0,0, $pixel);

90           alternating on and off segments of the lengths specified in list of
91           dashes. The manner in which the on and off segments are drawn is
92           determined by the line_style value of the GC.
