I had a bug in my code and found that my Custom SubClas Listbox returns Nil in the case below:
MyCustomLB.Parent.Child.Title = "My nice WIndow"
The code is based on:
LB.Parent.Child.Title = "My nice WIndow"
Where LB is a standard Listbox Control.
To be able to do that, I passed the window as parameter and all is clear.
Is it standard behavior ?
