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.
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.
