All known Subclasses: com.sun.midp.main.NativeDisplayControllerPeer,
| MVMDisplayController | | public class MVMDisplayController extends DisplayController (Code) | | This class controls which MIDlet's display is in the foreground.
Running only in the AMS Isolate (0) the controller consulted by the MIDlet
proxy list for any foreground when various state changes occur in a MIDlet.
The display controller defers the display decision to the user by choosing
the foreground selector to be the next foreground.
From the user perspective when the last MIDlet the user launched sets its
current displayable for the first time, that MIDlet should automatically
get the foreground (see the midletCreated and foregroundRequest methods).
A MIDlet that is paused or destroyed is treated as if it has requested the
background as described above.
