DESCRIPTION

24       Gtk2::ImageView::Nav is a popup window that shows a downscaled preview
25       of the pixbuf that Gtk2::ImageView is showing. The user can drag around
26       a rectangle which indicates the current view of the image.
27
28       This class is used by Gtk2::ImageView::ScrollWin itself. It is probably
29       not very useful for clients of this library.
30
31       Gtk2::ImageView::Nav has the same keybindings that Gtk2::ImageView has.
32       All keypresses that it receives are passed along to the view.
33

METHODS

35   widget = $view->new
36       Returns a new Gtk2::ImageView::Nav for showing thumbnails of the view.
37       The pixbuf is by default undef.
38
39   $nav->grab
40   pixbuf = $nav->get_pixbuf
41       Returns the downscaled pixbuf of the views pixbuf that this
42       Gtk2::ImageView::Nav shows, or undef if that pixbuf has not been
43       created yet.
44
45       The pixbuf is by default undef.
46
47   $nav->release
48   $nav->show_and_grab ($center_x, $center_y)
49       ·   $center_x (integer)
50
51       ·   $center_y (integer)
52
53       Returns the Gtk2::ImageView::Nav centered around the point (center_x,
54       center_y) and grab mouse and keyboard events. The grab continues until
55       a button release event is received which causes the widget to hide.
