Position Handler Demo
This demo shows how to customize and restrict the movement behavior of nodes.
This is done with custom implementations of the interface
IPositionHandler that are added to the lookup of the nodes.
Things to Try
Select and move the nodes.
- Red nodes are unmovable.
Green nodes move only vertically or horizontally
from the current start point.
Orange nodes move freely within the displayed
rectangle but cannot leave it.
Blue nodes combine the green and orange
restrictions: they move only vertically or horizontally and cannot leave the rectangle.
