How can I display a value in a textbox that updates as the cursor moves in the drawing? Specifically I want the user to select a polyline and I want to show the distance in a textbox from the beginning as the cursor moves.
Hi, (dcl-control-settext <textcontrol> (rtos (distance ptStart ptEnd) 2 2)) should do the trick.
It will only work with one of the modeless forms.
The hardest work should be to get noticed about mousecursor moves. I believe you should study the available Lisp-reactors or open a question in any Lisp forum.
Regards, Fred

What's about "grread"?
Hi, Peter, yes, I thought about it, but I wasn't sure whether grread would work while gripediting is active.
