Manual Reference Pages - GTK2::IMAGEVIEW::NAV (3)
Gtk2::ImageView::Nav - Navigation window showing a thumbnailed overview of a Gtk2::ImageView.
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.
widget = CW$view->new
Returns a new Gtk2::ImageView::Nav for showing thumbnails of the view. The
pixbuf is by default undef.
pixbuf = CW$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.
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.
CW$nav->show_and_grab ($center_x, CW$center_y)
