Okay, I just helped myself and changed the code :
1. I've added a new option :
.... , onClick: false ....
2. In the objectcreation I've changed the click event :
...
// give a CallBack to the user.....
if (p.onClick)
p.onClick();
...
3. Object creation as follows :
...
onClick: function() { showSub(); }
...
Now I will try to return some parameters of/to the onClick function
(f.e. id of the selected row or similiar data...).
Hope this is allowed...
