Advanced PowerBuilder

Inheriting a Window

In the descendent window, you can do any of the following:

• Override or extend the inherited events scripts.
• Override and extend some events scripts.
• Override/Overload object functions.
• Reference the ancestor's events, functions (as long as they aren't declared as private).
• Change attributes of controls and the content of variables.

These are the things that you can't do:

• Delete any control in the descendent window if they are painted in the ancestor.
• Change the names of the inherited controls in descendant window.

You can change the position of controls in the descendant window, but if you do so, further changes to the position of the control in the ancestor window will not be reflected in the descendant window. The same is true for changes made to any other attribute in the descendant window - It is something like overriding ancestor attribute values.
