Browsing the class hierarchy
PowerBuilder provides a Browser that can show the hierarchy
of the built-in PowerBuilder system objects and the hierarchy of ancestor
and descendent windows, menus, and user objects you create. In object-oriented
terms, these are called class hierarchies:
each PowerBuilder object defines a class.
To browse the class hierarchy of PowerBuilder system
objects:
-
Click the Browser button in the PowerBar.
The Browser displays.
- Choose the System tab to show the built-in PowerBuilder objects.
-
In the left pane, scroll down the object list
and select the powerobject. -
Display the popup menu for the powerobject and
choose Show Hierarchy. -
Select Expand All from the popup menu and scroll
to the top.The hierarchy for the built-in PowerBuilder objects displays.
Getting context-sensitive Help in the Browser To get context-sensitive Help for an object, control, or function,
select Help from its popup menu.
To display the class hierarchy for other object
types:
-
Choose the Menu, Window, or User Object
tab.If you choose any other object type, there is no inheritance
for the object type, so you can’t display a class hierarchy. -
In the left pane, select an object and choose
Show Hierarchy from its popup menu. -
Select an object and choose Expand All from its
popup menu.PowerBuilder shows the selected object in the current application. Descendent
objects are shown indented under their ancestors.
Regenerating objects
The Browser provides a convenient way to regenerate objects
and their descendants.

library entries”.
