Expand description

Values that can be passed to the vfunc::Gtk::Widget::system_setting_changed vfunc.

The values indicate which system setting has changed. Widgets may need to drop caches, or react otherwise.

Most of the values correspond to Settings properties.

More values may be added over time.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dpi

FontName

The property::Settings::gtk-font-name setting has changed

FontConfig

The font configuration has changed in a way that requires text to be redrawn. This can be any of the property::Settings::gtk-xft-antialias, property::Settings::gtk-xft-hinting, property::Settings::gtk-xft-hintstyle, property::Settings::gtk-xft-rgba or property::Settings::gtk-fontconfig-timestamp settings
