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 item's state changes.
Indicates whether arrows should be drawn. Possible values are:
The item at which this connection starts.
The item at which this connection ends.
This subroutine is called by Glib::Object::Subclass as the object is being instantiated. You should not call this subroutine directly. Leave it alone.
This subroutine is called by Glib::Object::Subclass when a property is being set. You should not call this subroutine directly. Leave it alone. Instead call the
set method to assign values to properties.
Connect the Gtk2::Ex::MindMapView::Connection to the items it observes.
Disconnect the Gtk2::Ex::MindMapView::Connection from the items it observes.
Error message from libart "*** attempt to put segment in horiz list twice" occurs when drawing 'two-way' arrows.
With 'two-way' arrows the arrow pointing back to the predecessor item is partially covered by the toggle.
