sourcefn strv(&self, key: &str) -> StrV
fn strv(&self, key: &str) -> StrV
A convenience variant of g_settings_get() for string arrays.
It is a programmer error to give a key that isn’t specified as
having an array of strings type in the schema for self.
key
the key to get the value for

a
newly-allocated, None-terminated array of strings, the value that
is stored at key in self.
sourcefn set_strv(&self, key: &str, value: impl IntoStrV) -> Result<(), BoolError>
fn set_strv(&self, key: &str, value: impl IntoStrV) -> Result<(), BoolError>
Sets key in self to value.
A convenience variant of g_settings_set() for string arrays. If
value is None, then key is set to be the empty array.
It is a programmer error to give a key that isn’t specified as
having an array of strings type in the schema for self.

true if setting the key succeeded,
false if the key was not writable
sourcefn bind<'a, P: IsA<Object>>(
&'a self,

) -> BindingBuilder<'a>
fn bind<'a, P: IsA<Object>>( &'a self, key: &'a str, object: &'a P, property: &'a str ) -> BindingBuilder<'a>
Create a binding between the key in the self object
and the property property of object.
The binding uses the default GIO mapping functions to map
between the settings and property values. These functions
handle booleans, numeric types and string types in a
straightforward way. Use [bind_with_mapping()][Self::bind_with_mapping()] if
you need a custom mapping, or map between types that are not
supported by the default mapping functions.
Unless the flags include SettingsBindFlags::NO_SENSITIVITY, this
function also establishes a binding between the writability of
key and the “sensitive” property of object (if object has
a boolean property by that name). See SettingsExt::bind_writable()
for more details about writable bindings.
Note that the lifecycle of the binding is tied to object,
and that you can have only one binding per object property.
If you bind the same property twice on the same object, the second
binding overrides the first one.
