The status line normally shows its permanent or "normal" message;
when moving the mouse over a widget which provides status line help, the
status line temporarily replaces its normal message with the help
information; the status line obtains this help message by sending the
widget a ID_QUERY_HELP message with type SEL_UPDATE. If
this query does not result in a new
status string, the target of the status line is tried via an ordinary
SEL_UPDATE message. If none of the above work, the status
line will display the normal text (i.e. the string set via the normalText=
accessor method). If the message contains a newline character, then the
part before the newline will be displayed in the highlight color, while the
part after the newline will be shown using the normal text color.
Events
The following messages are sent by FXStatusLine to its target:
SEL_UPDATE: | Sent when the widget currently under the mouse cursor doesn‘t respond
to a SEL_UPDATE message with identifier ID_QUERY_HELP, as
described above.
