## 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)

  Image View to navigate
