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::ustring & type
)

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

A Glib::wrap() method for this object.

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.
