DESCRIPTION

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.

METHODS

widget = CW$view->new

Returns a new Gtk2::ImageView::Nav for showing thumbnails of the view. The pixbuf is by default undef.

CW$nav->grab

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.

CW$nav->release

CW$nav->show_and_grab ($center_x, CW$center_y)

o $center_x (integer)
o $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.

PROPERTIES

’view’ (Gtk2::ImageView : default undef : writable / construct-only) Image View to navigate
