Connecting to 3270 Screen parts
To build an application that provides a graphical front end to a 3270-based host application, you must add a separate 3270 Screen part for each of the host screens your user needs to interact with. To connect to 3270 Screen parts, do the following:
1. Use the Key sequence validation string, in the 3270 Screen Settings window or the keyString attribute, which you can specify in the part's Settings window, to detect when the host screen it represents has become active. The 3270 Screen part's public interface provides features that help you do the following:
o Determine which 3270 Screen part is active (based upon which host screen is currently displayed)
o Identify the positions and lengths of all input and output fields
o Read from and write to the screen
o Send control keystrokes such as Enter, PF, and PA keys
2. Make the appropriate connections to communicate with the 3270 Screen part.
