Verifying children in controls list

To verify that the correct children are in the controls list, perform the following operations:

• The default controls list specifies all objects that are possible children (AllWidgets). If your object can have gadget children, change this to include gadgets. (AllWidgetsAndGadgets).
• If your object can have only specific children, edit the controls list by hand.
• Check that the number of children is correctly set. By default any object that can have children can have an unlimited number of children (see "Objects that Control Specific Children" ).
