5.5.1.3. Screen Controller
Screen controller is a Java or Groovy class, linked to an XML-descriptor and containing screen initialization and event handling logic.
Controller should be inherited from one of the following base classes:
-
AbstractFrame − for implementation of frames.
-
AbstractWindow − for implementation of simple screens.
-
AbstractLookup − for implementation of lookup screens.
-
AbstractEditor − for implementation of edit screens.

Tip
|
If a screen does not need additional logic, it can use the base class itself as a controller – |
Controller class should be registered in class attribute of the root element window in a screen’s XML descriptor.
