Enum gtk4::SystemSetting
source · #[non_exhaustive]
pub enum SystemSetting {
Dpi,
FontName,
FontConfig,
Display,
IconTheme,
}
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
the gtk-xft-dpi
setting has changed
FontName
The 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
gtk-xft-antialias
,
gtk-xft-hinting
,
gtk-xft-hintstyle
,
gtk-xft-rgba
or
gtk-fontconfig-timestamp
settings
Display
The display has changed
IconTheme
The icon theme has changed in a way that requires icons to be looked up again
