rcResetStyles

This function recomputes the styles for all widgets that use a particular #GtkSettings object. (There is one #GtkSettings object per #GdkScreen, see [gtk.settings.Settings.getForScreen]); It is useful when some global parameter has changed that affects the appearance of all widgets, because when a widget gets a new style, it will both redraw and recompute any cached information about its appearance. As an example, it is used when the default font size set by the operating system changes. Note that this function doesn’t affect widgets that have a style set explicitly on them with [gtk.widget.Widget.setStyle].
