Graphics.UI.Gtk.ImageView.ImageNav

Details

ImageNav is a popup window that shows a downscaled preview of the pixbuf that ImageView is showing. The user can drag around a rectangle which indicates the current view of the image.

This class is used by ImageScrollWin itself. It is probably not very useful for clients of this library.

ImageNav has the same keybindings that ImageView has. All keypresses that it receives are passed along to the view.
