Displaying fields on a temporary pair of managers
You can use the EyelidFieldManager class to display fields on a pair of managers that appear on the top and bottom of the screen temporarily.
By default, the fields appear when the BlackBerry® device user moves the trackball or, for a device with a touch screen, when a touch event occurs. The fields disappear after a period of inactivity (1.2 seconds by default). You can override these default properties.
There is no limit to the number and size of the fields. If the managers contain more fields than can fit on the screen, the top and bottom managers overlap with the top manager in the foreground.
