How to draw an arrow at the end of a line?????????????

[steve smith]

Hi here is the probrlm i have, say i have two boxes drawn box1, and
box2, and box1 is connected to box2, i want to be able to draw a line
indicating the direction of the connection by means of an arrow. Is
there any way this can be done? I have it working where the two boxes
are connected by a line, but i could really do with an arro at the end
of the line to ndicate direction, any help much appreciated thanks.

Work out the positions of a the vertices of a triangle (or other,
prettier polygon) which you can use for an arrowhead, then use
Graphics.fillPolygon(), Graphics.drawPolygon() or
Graphics.drawPolyLine() to draw it. If the line is horizontal or
vertical, this is trivial, otherwise it requires a little trig. and some
tinkering with the values to allow for pixel boundaries.
