Not to rush you in any way, Egon, but I was wondering if you already have a beta of 1.18 with that in so that I don't have to do it differently on my code and have to change it later.
No, not yet...i'll try to add it today, but i can't promise it.
Here you go: http://www.jpct.net/download/beta/jpctapi_118pre3.zip (http://www.jpct.net/download/beta/jpctapi_118pre3.zip)
The method is called setObjectsVisibility(<boolean>);
Thanks a whole lot, pal.
