       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

               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);

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 )

       Adds widget to this status bar. widget is reparented if it isn't already a child of the

       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

       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
