Description:

You can use PtLine to create line primitives.

PtLine

A PtLine widget.

A line is defined by the origin and two points:

Pt_ARG_ORIGIN: Origin for the line's coordinate space.
Pt_ARG_POINTS: The line's start and end points. If you don't set these points, no line is rendered.

For more information, see PtGraphic.

Inherited resources:

If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
