Gtk2::Pango - constants for use with Pango
use Gtk2; # gets the actual Pango objects and methods use Gtk2::Pango; # load extra constants
To use Pango effectively, you need a few extra constants that are not supplied in normal ways by the type system or by other means.
This module exports all of those extra constants when you load it. They use the fully-prefixed names from the C documentation.
PangoWeight is indeed defined as an enumerated type whose values can be used as nickname strings in the perl bindings, but in several places where a weight is needed, a gint is requested instead. This is because PangoWeight is actually just a set of predefined values for an integer-valued property. The PANGO_WEIGHT_* constants give you the predefined values:
PANGO_WEIGHT_ULTRALIGHT PANGO_WEIGHT_LIGHT PANGO_WEIGHT_NORMAL PANGO_WEIGHT_BOLD PANGO_WEIGHT_ULTRABOLD PANGO_WEIGHT_HEAVY
These are #defined in the C source, and thus are not available anywhere except here:
PANGO_SCALE_XX_SMALL PANGO_SCALE_X_SMALL PANGO_SCALE_SMALL PANGO_SCALE_MEDIUM PANGO_SCALE_LARGE PANGO_SCALE_X_LARGE PANGO_SCALE_XX_LARGE
PANGO_SCALE is needed to convert between Pango units and pixels. It is also available as Gtk2::Pango->scale.
This module shouldn't exist, but some parts of the API just aren't clean.
This stuff is hardcoded directly from the headers of pango 1.2.1.
