calling super class constructure

Former Member — Tue, 07 Aug 2007 17:43:51 GMT

Hi,

I have created two classes, class A and sub class- classB, using class builder how can I call consture of super class A .

getting following error - In the constructor method, you can only access instance attributes

after the constructor of the superclass (SUPER->CONSTRUCTOR) has been

called.

Thanks for you help.

If your class B inherits from class A, make sure that you specify so in the attributes tab, then in the constructor of class B, make sure to call the super->constructor.

call method super->constructor( ).

Similar to this in a local class.
