5 GMI Applet Application
The GMI Applet is closely related to the GMI application, but there are some small differences.
The similarities between GMI Appler and GMI include:
 Both will model the application interface based on the obtained html page.
 Both supports cross-domain interaction (between the user-defined webserver and
the built-in GMI server on the phone) and supports the same GMI API functions.
The differences are:
 GMI Applet is a desktop plugin application while GMI application will need to
launch a separate application.
 Since GMI Appletis a desktop plugin application and the softkeys/navigation
buttons are being used by the desktop application; therefore, the Backspace and the
Shift keys are used to replace the F3 and F4 keys. When writing the GMI Applet
Application source code, the Backspace key event should be mapped to the F4 key
event and the Shift key event should be mapped to the F3 event.
