The default implementation of a ListField on a BlackBerry device will display text in a number of selectable rows. It is possible to expand on this behaviour and allow an application to add a series of check boxes to the list. This can provide a visual indication to the user of rows that have some significance to the application. In the attached sample application, check boxes are added to the left side of a ListField. The boxes can be checked and unchecked by highlighting the appropriate row and by either pressing the SPACEBAR or selecting Change Option from the menu. Here is a screenshot of what the list looks like with the first row highlighted on a BlackBerry 7290 Wireless Handheld™ with BlackBerry Device Software 4.1.
