	)

Loads a loadable icon.

For the asynchronous version of this function, see load_async().

Parameters

size	an integer.
type	a location to store the type of the loaded icon
cancellable	a Cancellable object

Returns: a InputStream to read the icon from.

◆ load_async() [1/2]

void Gio::LoadableIcon::load_async	(	int	size,
		const SlotAsyncReady &	slot
	)

Non-cancellable version of load_async()

◆ load_async() [2/2]

void Gio::LoadableIcon::load_async	(	int	size,
		const SlotAsyncReady &	slot,
		const Glib::RefPtr< Cancellable > &	cancellable
	)

Loads an icon asynchronously.

To finish this function, see load_finish(). For the synchronous, blocking version of this function, see load().

Parameters

size	an integer.
cancellable	a Cancellable object
slot	a function to call when the request is satisfied

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
