Used - to explain tool tip texts or menu entries, for example. - \i \e Normal - occupies part of the status bar and may be hidden - by temporary messages. Used to display the page and line - number in a word processor, for example. - \i \e Permanent - is never hidden. Used for important mode - indications, for example, some applications put a Caps Lock - indicator in the status bar. - \endlist - - TQStatusBar lets you display all three types of indicators. - - To display a \e temporary message, call message() (perhaps by - connecting a suitable signal to it). To remove a temporary - message, call clear(). There are two variants of message(): one - that displays the message until the next clear() or message() and - one that has a time limit: - - \code - connect( loader, TQT_SIGNAL(progressMessage(const TQString&)), - statusBar(), TQT_SLOT(message(const TQString&)) ); - - statusBar()->message("Loading..."); // Initial message - loader.loadStuff(); // Emits progress messages - statusBar()->message("Done.", 2000); // Final message for 2 seconds - \endcode - - \e Normal and \e Permanent messages are displayed by creating a - small widget and then adding it to the status bar with - addWidget(). Widgets like TQLabel, TQProgressBar or even TQToolButton - are useful for adding to status bars. removeWidget() is used to - remove widgets. - - \code - statusBar()->addWidget(new MyReadWriteIndication(statusBar())); - \endcode - - By default TQStatusBar provides a TQSizeGrip in the lower-right - corner.
