gtk:volume-button-use-symbolic (object)

object -- a gtk:volume-button widget
setting -- a boolean whether to use symbolic icons

The accessor for the use-symbolic slot gets or sets whether to use symbolic icons as the icons. Note that if the symbolic icons are not available in your installed theme, then the normal, potentially colorful icons will be used. The gtk:volume-button implementation has been deprecated since version 4.10 and should not be used in newly written code. This widget will be removed in GTK 5.
