SYNOPSIS

use Gtk2::Ex::MindMapView::Connection;

This module is internal to Gtk2::Ex::MindMapView. Connections are instantiated by Gtk2::Ex::MindMapView. This module is responsible for drawing the connecting lines between Gtk2::Ex::MindMapView::Items onto the canvas.

The Gtk2::Ex::MindMapView::Connection is an observer. It registers with the view items so that it may be notified when a view items state changes.
