I was trying to make a subgraph that allows the user to drag and drop GoNode objects inside it.
I found a probem in this procedure that happened to exist in the SubGraph sample application.
If the user resized the subgraph before dropping the node, then dropped the node near the resized side, the resized side moves again making a new margin between it and the newly dropped object.
How can I prevent the SubGraph from automatically resizing??
Another question: What is the best way to support external dragging and dropping from a GoPalette inside my subgraph?
