PowerBuilder uses this syntax to show names of inherited controls:
ancestorwindow::control
For example, if you select the Open button in w_customer,
which is inherited from w_ancestor,
its name displays on the General page in the properties view as w_ancestor::cb_open.
Names of controls must be unique in an inheritance hierarchy. For example, you cannot have a CommandButton named cb_close defined in an ancestor and a different CommandButton named cb_close defined in a child. You should develop a naming convention for controls in windows that you plan to use as ancestors.
