Thanks for the answer of my earlier question. (By Maurice). I would like to know if there is an easy way to make a x-window application using gpc. Do I have to use "external" and in that way use the C generated libraries? Then I also need to create a lot of records that resembles the structs normally used when doing this in C? Or is there a "header file" usable from gpc, so I dont have to rewrite all that is in Xlib.h? best regards /Anders
