The Natural Studio plug-in example demonstrates how the Natural Studio metastructure can be extended with plug-ins that define your own object types, assign commands to them and display objects as nodes in tree views and list views.
The plug-in example shows information about the Natural application programming
interfaces contained in the library SYSEXT. It allows users to list their
documentation and to execute a test program for each of the application programming
interfaces.
The source code of the plug-in example is delivered in the library SYSEXPLG.
It is intended to give an impression of how plug-ins can be implemented with Natural
Studio.
The following topics are covered below:
The plug-in example is installed automatically during Natural Studio installation. Initially, the activation of plug-ins is disabled. Therefore, in order to use the plug-in example, you must first enable plug-in activation and then activate the plug-in example.
To activate the plug-in example
Make sure that plug-in activation has been enabled. See Workspace Options in the documentation Using Natural Studio.
Invoke the Plug-in Manager as described in Invoking the Plug-in Manager in the documentation Using Natural Studio.
In the Plug-in Manager window, select Plug-in Example.
Activate the plug-in example as described in Activating and Deactivating a Plug-in in the documentation Using Natural Studio.
When the plug-in example has been activated in the Plug-in Manager, the following additional elements are available in the Natural Studio window.
The menu provides the cascading menu with the following commands:
| Command | Description |
|---|---|
If an application programming interface (subprogram
USRnnnnN), its description (text
member USRnnnnT) or its test program
(program USRnnnnP) is selected in
library SYSEXT, this command displays information about this
application programming interface in a tree view window. If none of the above
is selected, this command displays information about all application
programming interfaces in a tree view window.

|
| Displays the same information as above in a list view window. |
The cascading menu with the above commands is available in the context menus of the Natural object types program, subprogram and text.
An additional toolbar is shown. The toolbar buttons represent the following menu commands:
