Hi,
I'm having a hack at the code for arrow heads, but I've got myself properly confused.
It seems that we have the SPItem class hierarchy (which contains SPMarker) and the repr tree, and that these are kept in sync with each other. So in which tree should I create my new marker object? AFAICS my alternatives are:
1. Do a sp_repr_new ("marker"), add it to the defs repr, set up the attributes using sp_repr_set_attr () etc. etc.
2. Create a SPMarker, and set up its struct with the required bits.
So which should it be? And how to I propagate my changes from one tree to the other?
I've just tried the first approach above and it works fine, except that the arrow heads only appear when you re-load the file. I think this is because a SPMarker is never created / initialised.
Any enlightenment would be greatly appreciated.
