## Function Documentation

## ◆ PT()

PT | ( | GeomNode |  | ) |

Returns a GeomNode that represents the mouse trail.

The intent is that you should reparent this GeomNode to Render2D, and then forget about it. The MouseWatcher will continually update the trail node. There is only one trail node, it does not create a new one each time you call get_trail_node.

This is not a particularly beautiful way to render a mouse trail. It is intended more for debugging purposes than for finished applications. Even so, It is suggested that you might want to apply a line thickness and antialias mode to the line — doing so makes it look a lot better.
