Provided Methods§

source

fn bind_matrix_setting( &self, settings: &impl IsA<Settings>, key: &str, flags: SettingsBindFlags )

Binds the matrix property to a gio::Settings key.

The gio::Settings key must be of the same type as the matrix property, that is, "au".

The SettingsExtManual::bind() function cannot be used, because the default GIO mapping functions don’t support glib::Variant properties (maybe it will be supported by a future GIO version, in which case this function can be deprecated).

`settings`

a gio::Settings object.

`key`

the settings key to bind.

`flags`

flags for the binding.

source

fn enables_matrix(&self) -> bool

Returns

whether the matrix property is enabled.

source

fn matrix(&self) -> Option<Variant>

Gets the value of the matrix property, as a glib::Variant. An empty array can be returned in case the matrix is a zero matrix.

The types_for_locations() function may be more convenient to use.

Returns

the matrix value as a new floating glib::Variant instance.

source

fn types_for_locations(&self, locations: SpaceLocationFlags) -> SpaceTypeFlags

If only one location is specified, this function returns what kind of white spaces are drawn at that location. The value is retrieved from the matrix property.

If several locations are specified, this function returns the logical AND for those locations. Which means that if a certain kind of white space is present in the return value, then that kind of white space is drawn at all the specified locations.
