Title bar in Blackberry

Use a title bar to provide BlackBerry device users with information at the top of your application. Most title bars contain only a title, but title bars can display the following items:

• application icon, descriptive title, and time
• application notifications, such as a new message indicator
• wireless connection indicators, including the wireless coverage level, network coverage, GPS indicator, Bluetooth indicator, and Wi-Fi connection indicator
• battery power indicator
• active call indicator 

StandardTitleBar myTitleBar = new StandardTitleBar()

            .addIcon("my_logo.png")
            .addTitle("Title Bar")
            .addClock()
            .addNotifications()
            .addSignalIndicator();

myTitleBar.setPropertyValue(StandardTitleBar.PROPERTY_BATTERY_VISIBILITY,
            StandardTitleBar.BATTERY_VISIBLE_LOW_OR_CHARGING);
setTitleBar(myTitleBar);
