Detailed 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.

Typically, a request for the status bar functionality occurs in relation to a QMainWindow object. QMainWindow provides a main application window, with a menu bar, tool bars, dock widgets and a status bar around a large central widget. The status bar can be retrieved using the QMainWindow::statusBar() function, and replaced using the QMainWindow::setStatusBar() function.

Use the showMessage() slot to display a temporary message:

void MainWindow::createStatusBar()
{
statusBar()->showMessage(tr("Ready"));
}

To remove a temporary message, use the clearMessage() slot, or set a time limit when calling showMessage().

void MainWindow::print()
{
#ifndef QT_NO_PRINTDIALOG
QTextDocument *document = textEdit->document();
QPrinter printer;
QPrintDialog *dlg = new QPrintDialog(&printer, this);
if (dlg->exec() != QDialog::Accepted) {
return;
}
document->print(&printer);
statusBar()->showMessage(tr("Ready"), 2000);
#endif
}

Use the currentMessage() function to retrieve the temporary message currently shown. The QStatusBar class also provide the messageChanged() signal which is emitted whenever the temporary status message changes.

Normal and Permanent messages are displayed by creating a small widget (QLabel, QProgressBar or even QToolButton) and then adding it to the status bar using the addWidget() or the addPermanentWidget() function. Use the removeWidget() function to remove such messages from the status bar.

statusBar()->addWidget(new MyReadWriteIndication);

By default QStatusBar provides a QSizeGrip in the lower-right corner. You can disable it using the setSizeGripEnabled() function. Use the isSizeGripEnabled() function to determine the current status of the size grip.

QMainWindow, QStatusTipEvent

Constructor & Destructor Documentation

QStatusBar::QStatusBar ( QWidget parent = nullptr)
explicit

Constructs a status bar with a size grip and the given parent.

See also
setSizeGripEnabled()
QStatusBar::~QStatusBar ( )
virtual

Destroys this status bar and frees any allocated resources and child widgets.

Method Documentation

void QStatusBar::addPermanentWidget ( QWidget widget,
int  stretch = 0 
)

Adds the given widget permanently to this status bar, reparenting the widget if it is not already a child of this QStatusBar object. The stretch parameter is used to compute a suitable size for the given widget as the status bar grows and shrinks. The default stretch factor is 0, i.e giving the widget a minimum of space.

Permanently means that the widget may not be obscured by temporary messages. It is is located at the far right of the status bar.

See also
insertPermanentWidget(), removeWidget(), addWidget()
void QStatusBar::addWidget ( QWidget widget,
int  stretch = 0 
)

Adds the given widget to this status bar, reparenting the widget if it is not already a child of this QStatusBar object. The stretch parameter is used to compute a suitable size for the given widget as the status bar grows and shrinks. The default stretch factor is 0, i.e giving the widget a minimum of space.

The widget is located to the far left of the first permanent widget (see addPermanentWidget()) and may be obscured by temporary messages.

See also
insertWidget(), removeWidget(), addPermanentWidget()
void QStatusBar::clearMessage ( )
slot

Removes any temporary message being shown.

See also
currentMessage(), showMessage(), removeWidget()
QString QStatusBar::currentMessage ( ) const

Returns the temporary message currently shown, or an empty string if there is no such message.

See also
showMessage()
bool QStatusBar::event ( QEvent event)
overrideprotected

Reimplemented from QObject::event().

void QStatusBar::hideOrShow ( )
protected

Ensures that the right widgets are visible.

Used by the showMessage() and clearMessage() functions.

int QStatusBar::insertPermanentWidget ( int  index,
QWidget widget,
int  stretch = 0 
)

Inserts the given widget at the given index permanently to this status bar, reparenting the widget if it is not already a child of this QStatusBar object. If index is out of range, the widget is appended (in which case it is the actual index of the widget that is returned).

The stretch parameter is used to compute a suitable size for the given widget as the status bar grows and shrinks. The default stretch factor is 0, i.e giving the widget a minimum of space.

Permanently means that the widget may not be obscured by temporary messages. It is is located at the far right of the status bar.

See also
addPermanentWidget(), removeWidget(), addWidget()
int QStatusBar::insertWidget ( int  index,
QWidget widget,
int  stretch = 0 
)

Inserts the given widget as a child of the current QStatusBar at the given index. If index is not a valid position the widget is appended and the index where the widget was added is returned.

The value for stretch is used to change the size for the given widget as the status bar grows and shrinks. The default stretch factor is 0, which gives the widget the minimum amount of space.

See also
addWidget(), removeWidget(), addPermanentWidget()
bool QStatusBar::isSizeGripEnabled ( ) const

Documentation pending.

void QStatusBar::messageChanged ( const QString msg)
signal

This signal is emitted when the temporary status message changes. The message is passed in msg. If the new message is an empty string the message has been removed.

See also
showMessage(), clearMessage()
void QStatusBar::paintEvent ( QPaintEvent event)
overrideprotectedvirtual

Shows the temporary message in response to the paint event.

Reimplemented from QWidget.

void QStatusBar::reformat ( )
protected

Changes the status bar's appearance to account for item changes. Special subclasses may need this function, but geometry management will usually take care of any necessary rearrangements.

void QStatusBar::removeWidget ( QWidget widget)

Removes the specified widget from the status bar. This method does not delete the widget but hides it. To add the widget again, you must call both the addWidget() and show() functions.

See also
addWidget(), addPermanentWidget(), clearMessage()
void QStatusBar::resizeEvent ( QResizeEvent event)
overrideprotectedvirtual

Reimplemented from QWidget::resizeEvent().

Reimplemented from QWidget.

void QStatusBar::setSizeGripEnabled ( bool  )

Documentation pending.

void QStatusBar::showEvent ( QShowEvent event)
overrideprotectedvirtual

Reimplemented from QWidget::showEvent().

Reimplemented from QWidget.

void QStatusBar::showMessage ( const QString msg,
int  timeout = 0 
)
slot

Hides the normal status indications and displays the given msg for the number of milliseconds specified by timeout. If timeout> is 0, the message remains displayed until the clearMessage() slot is called or until the showMessage() slot is called again to change the message.
