Provided Methods§

source

fn load( &self, size: i32, cancellable: Option<&impl IsA<Cancellable>> ) -> Result<(InputStream, GString), Error>

Loads a loadable icon. For the asynchronous version of this function, see load_async().

`size`

an integer.

`cancellable`

optional Cancellable object, None to ignore.

Returns

a InputStream to read the icon from.

`type_`

a location to store the type of the loaded icon, None to ignore.

source

fn load_async<P: FnOnce(Result<(InputStream, GString), Error>) + 'static>( &self, size: i32, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

Loads an icon asynchronously. To finish this function, see g_loadable_icon_load_finish(). For the synchronous, blocking version of this function, see load().
