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           Creates a new Gtk2::ImageView::Nav for showing thumbnails of the
37           view. The pixbuf is by default NULL.
38
39           view : a Gtk2::ImageView.
40
41       Returns
42
43       a new Gtk2::ImageView::Nav showing the view.
44
45   $nav->grab
46   pixbuf = $nav->get_pixbuf
47           Returns the downscaled pixbuf of the views pixbuf that this
48           Gtk2::ImageView::Nav shows, or NULL if that pixbuf has not been
49           created yet.
50
51           The pixbuf is by default NULL.
52
53           nav : a Gtk2::ImageView::Nav.
54
55       Returns
56
57       the pixbuf in the navigation area this image navigator shows, or NULL
58       if none exist.
59
60   $nav->release
61   $nav->show_and_grab ($center_x, $center_y)
62           ·   $center_x (integer)
63
64           ·   $center_y (integer)
65
66           Show the Gtk2::ImageView::Nav centered around the point (center_x,
67           center_y) and grab mouse and keyboard events. The grab continues
68           until a button release event is received which causes the widget to
69           hide.
70
71           nav : a Gtk2::ImageView::Nav.
72           center_x : x coordinate of center position
73           center_y : y coordinate of center position
74
75       Returns
76
77       the pixbuf in the navigation area this image navigator shows, or NULL
78       if none exist.
