Constructor Detail

PInfranetApplet

public PInfranetApplet()

Creates a default instance of PInfranetApplet.

Method Detail

init

public void init()

Overrides the Applet.init() method. Subclasses that override this version of the init() method must call it first.

Overrides:

init in class Applet

start

public void start()

Overrides the Applet.start() method and issues a PContextChangedEvent. Be sure to call the super class if overridden.

Overrides:

start in class Applet

stop

public void stop()

Overrides the Applet.stop() method and issues a PContextChangedEvent. Be sure to call the super class if overridden.

Overrides:

stop in class Applet

destroy

public void destroy()

Overrides the Applet.destroy() method and issues a PContextChangedEvent. Be sure to call the super class if overridden.

Overrides:

destroy in class Applet

getServices

public PClientServices getServices()

A utility method that gets the client services.

Returns:

A client services object.

displayDefaultLogin

protected void displayDefaultLogin()

A utility method that displays a simple user/password login screen in the applet. It calls handleLoginAccepted if a valid login occurs.

displayLogin

protected void displayLogin(JComponent login)

A utility method that displays a specified login panel. This panel must conform to the following rules to work properly:

1. To perform the actual login, it must call PClientServices.doLogin().
2. If the login is accepted, it should call handleLoginAccepted, preferably in a separate thread.
3. If the login is not accepted, it should display a dialog to notify the user.

Parameters:

login - the user's login information

PClientServices

handleLoginAccepted

public void handleLoginAccepted()

A default login handler. Gets the object pointed to by the "screen" property/parameter. If the object is a URL, then the browser is directed there. Otherwise, it is assumed to be a bean to load and display.

loadComponent

protected void loadComponent(String name)

A utility method that attempts to load and display a bean into this applet.

Parameters:

name - the class name for the bean
