|
* @short_description: GObject integration support
|
|
* @include: hb-gobject.h
|
|
*
|
|
* Support for using HarfBuzz with the GObject library to provide
|
|
* type data.
|
|
*
|
|
* The types and functions listed here are solely a linkage between
|
|
* HarfBuzz's public data types and the GTypes used by the GObject framework.
|
|
* HarfBuzz uses GObject introspection to generate its Python bindings
|
|
* (and potentially other language bindings); client programs should never need
|
|
* to access the GObject-integration mechanics.
|
|
*
|
|
* For client programs using the GNOME and GTK software stack, please see the
|
|
* GLib and FreeType integration pages.
