## Member Function Documentation

static void Gio::LoadableIcon::add_interface | ( | GType | gtype_implementer | ) | `[static]`

Reimplemented from Gio::Icon.

const GLoadableIcon* Gio::LoadableIcon::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::Icon.

Reimplemented in Gio::FileIcon.

GLoadableIcon* Gio::LoadableIcon::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::Icon.

Reimplemented in Gio::FileIcon.

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

Non-cancellable version of load().

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.

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

Non-cancellable version of load_async().

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

## Friends And Related Function Documentation

Glib::RefPtr< Gio::LoadableIcon > wrap | ( | GLoadableIcon * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

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.
