MODULE = Gtk2::ImageView::Nav PACKAGE = Gtk2::ImageView::Nav PREFIX = gtk_image_nav_
=for object Gtk2::ImageView::Nav Navigation window showing a thumbnailed overview of a Gtk2::ImageView.
=head1 DESCRIPTION
Gtk2::ImageView::Nav is a popup window that shows a downscaled preview of the pixbuf that Gtk2::ImageView is showing. The user can drag around a rectangle which indicates the current view of the image.
This class is used by Gtk2::ImageView::ScrollWin itself. It is probably not very useful for clients of this library.
Gtk2::ImageView::Nav has the same keybindings that Gtk2::ImageView has. All keypresses that it receives are passed along to the view.
=cut
=for apidoc
Creates a new Gtk2::ImageView::Nav for showing thumbnails of the view. The pixbuf is by default NULL.
