Best practice: Implementing status dialog boxes
• Use a status dialog box when you cannot determine the duration of an operation. If you can determine the duration of
the operation, use a progress bar instead.
• Always indicate progress when the operation takes more than 1 second to complete.
• Do not include buttons in a status dialog box. If users can perform other actions when the status dialog box appears,
consider using another type of dialog box.
Banner and title bars
The banner, which appears at the top of the Home screen, displays the following items:
• Date, time, and wireless service provider
• Application notifications, such as the alarm indicator, missed call count indicator, unopened message count indicator,
and third-party indicators
• Wireless connection indicators, such as the wireless coverage level, network coverage, Bluetooth indicator, Wi-Fi
connection indicator, and roaming indicator
• Battery power indicator
• Sound profile indicator
• Search icon
The theme that users select on their BlackBerry device determines the design of the Home screen banner.
Although you cannot add a banner to your application, you can add an indicator to the banner to provide a notification or to
communicate important information about the status of your application. For example, you can include an unopened
message indicator and count to provide users with new message information.
You can add a title bar to the top of your application screens to help orient users. Most title bars contain only a title but title
bars can display the following items:
