public abstract class CNamedApplication

extends CApplication

Create a named application invoked by CJavaMenuItem widget. And initializes a connection to a server, typically a gateway such as cdevGateway if it is not connected.

The child class must provide a null constructor and the main method. It is also necessary to overwite the setArgs(String[]) method if there is any argument needed to be passed.

CNamedApplication is a subclass of CApplication and has a static hash table to keep track the running instance. Every time when the menu button is pressed, the CNamedApplication will search the hash table to find the instance with same name (args[0]). If the instance is found, the arguments will be reset (call application's setArgs method) and then the window will be brought to the front. If not found a new instance will be started up. By passing different argument the user can control the number of instance (window). Only one instance per name (using args[0] as the name or the empty string "" if no argument) will be shown up.
