Advanced PowerBuilder
Using Inheritance in
PowerBuilder
PowerBuilder supports inheritance from
three objects:
 |
Menus |
|
Windows |
|
User Objects |
You can inherit an object in one of the two
ways:
|
By selecting 'Inherit' from the Select
dialog box, which is brought up when you invoke the relevant object painter. |
|
By selecting 'File/Inherit...' from the
menu when you are in the relevant object painter. |
When an object is inherited, everything in
the ancestor object is passed onto the descendent. If another object is derived from the
descendent, the new object inherits everything from the first ancestor, as well as any new
definitions defined in its immediate ancestor.
