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. -- -- </description> -- <screenshot>gtk-fontsel</screenshot> -- <group>Selectors</group> -- <testgtk>create_font_selection.adb</testgtk> pragma Warnings (Off, "*is already use-visible*");
