static void Gio::LoadableIcon::add_interface ( GType  gtype_implementer )

static

static GType Gio::LoadableIcon::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

GLoadableIcon* Gio::LoadableIcon::gobj ( )

inline

Provides access to the underlying C GObject.

const GLoadableIcon* Gio::LoadableIcon::gobj ( ) const

inline

Provides access to the underlying C GObject.

Glib::RefPtr<InputStream> Gio::LoadableIcon::load	(	int	size,
		Glib::ustring&	type,
		const Glib::RefPtr< Cancellable >&	cancellable
	)

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.

Glib::RefPtr<InputStream> Gio::LoadableIcon::load	(	int	size,

Non-cancellable version of load()

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

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.
