gtk:font-chooser-widget-tweak-action (object)

object -- a gtk:font-chooser-widget widget
action -- a g:action toggle action

The accessor for the tweak-action slot of the gtk:font-chooser-widget class gets or sets the toggle action that can be used to switch to the tweak page of the font chooser widget. This lets the user tweak the OpenType features and variation axes of the selected font. The action will be enabled or disabled depending on whether the selected font has any features or axes. The gtk:font-chooser-widget implementation is deprecated since 4.10. Direct use of the gtk:font-chooser-widget widget is deprecated.
