Provided Methods§

source

fn get<U: FromVariant>(&self, key: &str) -> U

source

fn set(&self, key: &str, value: impl Into<Variant>) -> Result<(), BoolError>

source

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

§Returns

a newly-allocated, None-terminated array of strings, the value that is stored at @key in @self.

source

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.

§key

the name of the key to set

§value

the value to set it to, or None

§Returns

true if setting the key succeeded, false if the key was not writable

source

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 g_settings_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 g_settings_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.

§key

the key to bind

§object

a #GObject

§property

the name of the property to bind

§flags

flags for the binding

Object Safety§

This trait is not object safe.
