DESCRIPTION

       The QStatusBar class provides a horizontal bar suitable for presenting status information.

       Each status indicator falls into one of three categories:

       Temporary - briefly occupies most of the status bar. Used to explain tool tip texts or menu entries, for example.

       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.

       Permanent - is never hidden. Used for important mode indications, for example, some applications put a Caps Lock indicator in the status
       bar.

       QStatusBar lets you display all three types of indicators.

       To display a 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:

	       connect( loader, SIGNAL(progressMessage(const QString&)),
			statusBar(), SLOT(message(const QString&)) );
	       statusBar()->message("Loading...");  // Initial message
	       loader.loadStuff();		    // Emits progress messages
	       statusBar()->message("Done.", 2000); // Final message for 2 seconds

       Normal and Permanent messages are displayed by creating a small widget and then adding it to the status bar with addWidget(). Widgets like
       QLabel, QProgressBar or even QToolButton are useful for adding to status bars. removeWidget() is used to remove widgets.

	       statusBar()->addWidget(new MyReadWriteIndication(statusBar()));

       By default QStatusBar provides a QSizeGrip in the lower-right corner. You can disable it with setSizeGripEnabled(FALSE);

MEMBER FUNCTION DOCUMENTATION

QStatusBar::QStatusBar ( QWidget * parent = 0, const char * name = 0 )
       Constructs a status bar called name with parent parent and with a size grip.

       See also sizeGripEnabled.

QStatusBar::~QStatusBar () [virtual]
       Destroys the status bar and frees any allocated resources and child widgets.

void QStatusBar::addWidget ( QWidget * widget, int stretch = 0, bool permanent = FALSE ) [virtual]
       Adds widget to this status bar. widget is reparented if it isn't already a child of the QStatusBar.

       widget is permanently visible if permanent is TRUE and may be obscured by temporary messages if permanent is FALSE. The default is FALSE.

       If permanent is TRUE, widget is located at the far right of the status bar. If permanent is FALSE (the default), widget is located just to
       the left of the first permanent widget.

       stretch is used to compute a suitable size for widget as the status bar grows and shrinks. The default of 0 uses a minimum of space.

       This function may cause some flicker.

       See also removeWidget().

void QStatusBar::clear () [slot]
       Removes any temporary message being shown.

       See also message().

void QStatusBar::hideOrShow () [protected]
       Ensures that the right widgets are visible. Used by message() and clear().

bool QStatusBar::isSizeGripEnabled () const
       Returns TRUE if the QSizeGrip in the bottom right of the status bar is enabled; otherwise returns FALSE. See the "sizeGripEnabled" property
       for details.

void QStatusBar::message ( const QString & message ) [slot]
       Hides the normal status indicators and displays message until clear() or another message() is called.

       See also clear().

       Example: regexptester/regexptester.cpp.

void QStatusBar::message ( const QString & message, int ms ) [slot]
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       Hides the normal status indications and displays message for ms milli-seconds or until clear() or another message() is called, whichever
       occurs first.

void QStatusBar::messageChanged ( const QString & message ) [signal]
       This signal is emitted when the temporary status messages changes. message is the new temporary message, and is a null-string when the
       message has been removed.

       See also message() and clear().

void QStatusBar::paintEvent ( QPaintEvent * ) [virtual protected]
       Shows the temporary message, if appropriate.

       Reimplemented from QWidget.

void QStatusBar::reformat () [protected]
       Changes the status bar's appearance to account for item changes. Special subclasses may need this, but geometry management will usually
       take care of any necessary rearrangements.

void QStatusBar::removeWidget ( QWidget * widget ) [virtual]
       Removes widget from the status bar.

       This function may cause some flicker.

       Note that widget is not deleted.

       See also addWidget().

void QStatusBar::setSizeGripEnabled ( bool )
       Sets whether the QSizeGrip in the bottom right of the status bar is enabled. See the "sizeGripEnabled" property for details.

   Property Documentation
bool sizeGripEnabled
       This property holds whether the QSizeGrip in the bottom right of the status bar is enabled.

       Enables or disables the QSizeGrip in the bottom right of the status bar. By default, the size grip is enabled.

       Set this property's value with setSizeGripEnabled() and get this property's value with isSizeGripEnabled().
