Thank you David,
your code works fine. I kept looking at my code for at least twenty minutes
before I noticed a bug in the line:
store = gtk_tree_store_new(3, G_TYPE_STRING, GDK_TYPE_PIXBUF,
G_TYPE_BOOLEAN, G_TYPE_UINT);
This method would be much cooler if it could count number of parameters by
itself (I forgot to increment column count).
Regards,
Miroslav
