Package: Font_Selection

- Goto spec source

# Description

    package Gtk.Font_Selection is

This widget provides a nice way for the user of your application to select fonts. It first searches on your system for the list of fonts available, and displays a set of boxes to select them based on their name, their weight, their size, etc. This widget is provided in two forms, one widget that can be embedded in any container, a Gtk_Font_Selection, whereas the other one comes directly in its own separate window (to be popped up as a dialog).

Some filters can be applied to the widget, when you want the user to select only a font only among a specific subset (like bitmap or true-type fonts for instance). There are two kinds of filters: a base filter, set in your application and that the user can not change; a user filter that can be modified interactively by the user.
