As trivial as it may sounds painting an arrow at the end of a line (of

arbitrary angle) isn't easy afterall. The line crosses vertically from

(0,0) to (Width, Height) of a TGraphicControl. Now the idea is to draw

a polygon (triangle) with (0,0) and (x1,y1), (x2,y2) the points of its

edges. How do you calculate these values. Assume an arraw

with top angle of 30 degrees.

Any ideas?

Thanks
