/**
* The status line normally shows its permanent message.
* A semi-permanent message can override this permanent message, for example to
* indicate the application is busy or in a particular operating mode.
* The status line obtains the semi-permanent message by sending its target (if any)
* SEL_UPDATE message.
* A ID_SETSTRINGVALUE can be used to change the status message.
* When the user moves the cursor over a widget which has status-line help, the
* status line can flash a very temporarily message with help about the widget.
* For example, the status line may flash the "Quit Application" message when
* the user moves the cursor over the Quit button.
* The status line obtains the help message from the control by sending it a
* ID_QUERY_HELP message with type SEL_UPDATE.
* Unless the value is overridden, the status line will display the normal text,
* i.e. the string set via setNormalText().
* If the message contains a newline (\n), then the part before the newline
* will be displayed in the highlight color, while the part after the newline
* is shown using the normal text color.
