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.

METHODS

   widget = $view->new
       Returns a new Gtk2::ImageView::Nav for showing thumbnails of the view. The pixbuf is by default undef.

   $nav->grab
   pixbuf = $nav->get_pixbuf
       Returns the downscaled pixbuf of the views pixbuf that this Gtk2::ImageView::Nav shows, or undef if that
       pixbuf has not been created yet.

       The pixbuf is by default undef.

   $nav->release
   $nav->show_and_grab ($center_x, $center_y)
       •   $center_x (integer)

       •   $center_y (integer)

       Returns the Gtk2::ImageView::Nav centered around the point (center_x, center_y) and grab mouse and
       keyboard events. The grab continues until a button release event is received which causes the widget to
       hide.

PROPERTIES

       'view' (Gtk2::ImageView : default undef : writable / construct-only)
