gtk:font-chooser-font-features (object)

object -- a gtk:font-chooser object
features -- a string for the currently selected font features

The accessor for the font-features slot of the gtk:font-chooser class returns the currently selected font features, in a format that is compatible with CSS and with Pango attributes. The gtk:font-chooser implementation is deprecated since 4.10. Use the gtk:font-dialog and gtk:font-dialog-button widgets instead.
