List of all members.

## Detailed Description

A widget displaying an image.

The Gtk::Image widget displays an image. Various kinds of object can be displayed as an image; most typically, you would load a Gdk::Pixbuf ("pixel buffer") from a file, and then display that.

Gtk::Image is a subclass of Gtk::Misc, which implies that you can align it (center, left, right) and add padding to it, using Gtk::Misc methods.

Gtk::Image is a "no window" widget (has no Gdk::Window of its own), so by default does not receive events. If you want to receive events on the image, such as button clicks, place the image inside a Gtk::EventBox, then connect to the event signals on the event box.

## Member Function Documentation

void Gtk::Image::clear | ( |  | ) |

Glib::RefPtr<Gdk::PixbufAnimation> Gtk::Image::get_animation | ( |  | ) |

Gets the Gdk::PixbufAnimation being displayed by the Gtk::Image.

The storage type of the image must be Gtk::IMAGE_EMPTY or Gtk::IMAGE_ANIMATION (see get_storage_type()). The caller of this function does not own a reference to the returned animation.

Returns:
  The displayed animation, or `0` if the image is empty.

  The displayed pixbuf, or `0` if the image is empty.
