Hi all..
I have an implementation of The Conway Game Of Life which i am using to
experiment with the various drawing functions.
I had it working when using fl_rectf as the shape to draw and setting the
colour with
group->child(count)->color(n);
But with my polygons and new class designthat is not working..
My new class looks like this as I wanted to make the shape coords calculation
internal, but now i cannot get the widget to update its colours depending on
cell status after each generation as the algorithm runs
