How can I draw a line/arrow on the UIR in CVI (Decoration?)?

[CB4]

Is there an easy way to do this without using a picture?  I would like to be able to draw a line/arrow and rotate it to point at specific items in the UIR.

I think the easiest way to do this is to create a small canvas, set the background to transparant and draw your arrow using the CanvasDrawPoint function. The code below should draw you a nice arrow (make sure the canvas is large enough).

 SetCtrlAttribute (pnl, PNL_CANVAS, ATTR_PICT_BGCOLOR, VAL_TRANSPARENT);
 CanvasDrawLine (pnl, PNL_CANVAS, MakePoint (0, 8), MakePoint (30, 8));
 CanvasDrawLine (pnl, PNL_CANVAS, MakePoint (23, 1), MakePoint (30, 8));
 CanvasDrawLine (pnl, PNL_CANVAS, MakePoint (23, 15), MakePoint (30, 8));

I think it doesn't take too much time to figure out which coordinates to use to make the arrow point to another direction...

Success,

Wim

I'm not sure this will meet your rotating requirements, but also check out this thread....
