Z-Order Demo

This demo customizes editing gestures to keep the z-order of nodes consistent.

Usage

Select nodes and use the Raise/Lower/ToFront/ToBack buttons to change their z-orders.
Group/Ungroup select nodes and see how their relative z-order keeps stable.
Collapse/Expand group nodes and see how the z-order of their children keep stable.
Enter/Exit group or folder nodes and see how the z-order of nodes outside the group keep stable.
Cut/Copy/Paste selected nodes and see how the relative z-order of cut/copied nodes keeps stable when pasting.
Store the graph to GraphML and load it again to see how the z-order of the nodes keeps stable.
Undo/Redo any of these operations and see how the z-order is restored.
A z-order is valid in the graph or in a group, i.e. there is a z-order for all "first level" elements in the graph, as well as group specific z-orders for all elements in the specific groups.
