.SH "DESCRIPTION"
.IX Header "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.
.PP
This class is used by Gtk2::ImageView::ScrollWin itself. It is probably not very
useful for clients of this library.
.PP
Gtk2::ImageView::Nav has the same keybindings that Gtk2::ImageView has. All
keypresses that it receives are passed along to the view.

.ie n .SS "widget = $view\->\fBnew\fP"
.el .SS "widget = \f(CW$view\fP\->\fBnew\fP"
.IX Subsection "widget = $view->new"
Returns a new Gtk2::ImageView::Nav for showing thumbnails of the view. The
pixbuf is by default undef.
.ie n .SS "$nav\->\fBgrab\fP"
.el .SS "\f(CW$nav\fP\->\fBgrab\fP"

.el .SS "pixbuf = \f(CW$nav\fP\->\fBget_pixbuf\fP"
.IX Subsection "pixbuf = $nav->get_pixbuf"
Returns the downscaled pixbuf of the views pixbuf that this
Gtk2::ImageView::Nav shows, or undef if that pixbuf has not been created yet.
.PP
The pixbuf is by default undef.
.ie n .SS "$nav\->\fBrelease\fP"

.PP
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.
