Description

Procedure GetLine returns two user selected points, and draws a temporary "rubberband" line when prompting for the second point. This cannot be used if there is a function anywhere in the calling chain.

PROCEDURE GetLine(
          VAR p1X,p1Y   :REAL;
          VAR p2X,p2Y   :REAL);

def vs.GetLine(callback):
    return none

Parameters

p1		REAL		Returns coordinates of first user click.
p2		REAL		Returns coordinates of second user click.

Remarks

In Python this function will NOT block execution. It will execute a callback function with the resulted line (two points as callback function parameters).

Example

Python sample is similar to the sample in VS:GetPt.
