Description
Procedure GetPtL creates a temporary "rubberband" line from a specified point to the user selected end point. This cannot be used if there is a function anywhere in the calling chain.
PROCEDURE GetPtL(
p1X,p2Y :REAL;
VAR p2X,p2Y :REAL);
def vs.GetPtL(callback):
return None
Parameters
p1 REAL Coordinates of line start point. p2 REAL Returns coordinates of mouse 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
VectorScript
PROCEDURE Example; VAR pt1, pt2 :VECTOR; BEGIN GetPt(pt1.x, pt1.y); GetPtL(pt1.x, pt1.y, pt2.x, pt2.y); MoveTo(pt1.x, pt1.y); LineTo(pt2.x, pt2.y); END; RUN(Example);
Python sample is similar to the sample in VS:GetPt.
