DESCRIPTION

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

       Each status indicator falls into one of three categories:

       Temporary - occupies most of the status bar briefly. Used
              e.g. for explaining tool tip texts or menu entries.

       Normal - occupies part of the status bar and may be hidden
              by temporary messages. Used e.g. for displaying the
              page and line number in a word processor.

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

       QStatusBar lets you display all three types of indicator.

       To display a temporary message, call message(), perhaps by

       message, call clear(). There are two variants of
       message(), one which displays the message until the next
       clear() or mesage(), and one which also 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 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 this with
       setSizeGripEnabled(FALSE);

MEMBER FUNCTION DOCUMENTATION


QStatusBar::QStatusBar ( QWidget * parent = 0, const char * name

       = 0 )
       Constructs a status bar with just a size grip.

       See also setSizeGripEnabled().


QStatusBar::~QStatusBar ()

       Destructs the status bar and frees any allocated
       resources.


void QStatusBar::addWidget ( QWidget * widget, int stretch = 0,

       bool permanent = FALSE )
       Adds widget to this status bar.

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

       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.

       of the status bar. If permanent is FALSE (the default)
       widget is located just to the left of the first permanent
       widget.

       This function may cause some flicker.

       See also removeWidget().


void QStatusBar::clear () [slot]

       Removes any temporary message being shown.

       See also message().


bool QStatusBar::event ( QEvent * e ) [virtual protected]

       Reimplemented for internal reasons; the API is not
       affected.

       Reimplemented from QObject.


void QStatusBar::hideOrShow () [protected]

       Ensures that the right widgets are visible. Used by
       message() and clear().


bool QStatusBar::isSizeGripEnabled () const

       Returns whether the QSizeGrip in the bottom right of the
       status bar is enabled.

       See also setSizeGripEnabled().


void QStatusBar::message ( const QString & message ) [slot]

       Hide the normal status indicators and display message,
       until clear() or another message() is called.

       See also clear().


void QStatusBar::message ( const QString & message, int ms )

       [slot]
       Hide the normal status indications and display message for
       ms milli-seconds, or until clear() or another message() is
       called, whichever is first.


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 normally
       geometry management will take care of any necessary
       rearrangements.

       Removes widget from the status bar.

       This function may cause some flicker.

       Note that widget is not deleted.

       See also addWidget().


void QStatusBar::resizeEvent ( QResizeEvent * e ) [virtual

       protected]
       Reimplemented for internal reasons; the API is not
       affected.

       Reimplemented from QWidget.


void QStatusBar::setSizeGripEnabled ( bool enabled )

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

       See also  isSizeGripEnabled().
