gtk:font-chooser-font-map (fontchooser)

fontchooser -- a gtk:font-chooser widget
fontmap -- a pango:font-map object, or nil

Gets or sets the custom font map of the font chooser widget Returns nil if it does not have one. A custom font map can be used to present application specific fonts instead of or in addition to the normal system fonts. Note that other GTK widgets will only be able to use the application specific font if it is present in the font map they use. The following code updates the font map for a gtk:label widget with fontmap.

(setf (pango:context-font-map (gtk:widget-pango-context label)) fontmap)    

The gtk:font-chooser implementation is deprecated since 4.10. Use the gtk:font-dialog and gtk:font-dialog-button widgets instead.
