DESCRIPTIONGtk2::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.
widget = $view->newReturns a new Gtk2::ImageView::Nav for showing thumbnails of the view. The pixbuf is by default undef.
pixbuf = $nav->get_pixbufReturns 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.
$nav->show_and_grab ($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.
- 'view' (Gtk2::ImageView : default undef : writable / construct-only)
- Image View to navigate
