Re: [Extgraph-developer] Changes I've made (Was Improved drawing zoomed canvas)

[Marco W. <in...@ca...>]

The current code (yet not released) contains implementations for Nodes 
to have a Parent. This allows similar behaviour as you describe. In 
addition I have added some methods on the Node which can disable or 
enable clicking on it's ChildNodes. Similarly moving a Node will move 
all children, Visible and Lock will also be derivable over Parent Child 
relations.
