 122 A status bar is a narrow window that can be placed along the bottom of
 123 a frame to give small amounts of status information. It can contain
 124 one or more fields, one or more of which can be variable length
 125 according to the size of the window.
 126
 127 This example demonstrates how to create a custom status bar with actual
 128 gadgets embedded in it. In this case, the first field is just plain text,
 129 The second one has a checkbox that enables the timer, and the third
 130 field has a clock that shows the current time when it is enabled.
