Detailed Description

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

\inmodule QtWidgets

Each status indicator falls into one of three categories:

\list

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. \endlist

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:

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

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.

\target permanent message 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.

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.

Constructor & Destructor Documentation

◆ QStatusBar()

QStatusBar::QStatusBar ( QWidget * parent = nullptr )

explicit

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

See also: setSizeGripEnabled()

Definition at line 227 of file qstatusbar.cpp.

◆ ~QStatusBar()

QStatusBar::~QStatusBar ( )

virtual

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

Definition at line 246 of file qstatusbar.cpp.

Member Function Documentation

◆ addPermanentWidget()

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

Adds the given widget permanently to this status bar, reparenting the widget if it isn't 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()

Definition at line 330 of file qstatusbar.cpp.

Here is the call graph for this function:

◆ addWidget()

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

Adds the given widget to this status bar, reparenting the widget if it isn't 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()

Definition at line 265 of file qstatusbar.cpp.

Here is the call graph for this function:

◆ clearMessage

void QStatusBar::clearMessage ( )

slot

Removes any temporary message being shown.

Here is the caller graph for this function:

◆ currentMessage()

QString QStatusBar::currentMessage ( ) const

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

See also: showMessage()

Definition at line 582 of file qstatusbar.cpp.

◆ event()

bool QStatusBar::event ( QEvent * e )

overrideprotectedvirtual

\reimp

Reimplemented from QWidget.

Definition at line 691 of file qstatusbar.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ hideOrShow()

void QStatusBar::hideOrShow ( )

protected

Ensures that the right widgets are visible.

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

Definition at line 604 of file qstatusbar.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ insertPermanentWidget()

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

Since: 4.2

Inserts the given widget at the given index permanently to this status bar, reparenting the widget if it isn't 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.

Since: 4.2

Inserts the given widget at the given index to this status bar, reparenting the widget if it isn't 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.

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

signal

This signal is emitted whenever the temporary status message changes. The new temporary message is passed in the message parameter which is a null-string when the message has been removed.

◆ removeWidget()

void QStatusBar::removeWidget ( QWidget * widget )

Removes the specified widget from the status bar.

Note: This function does not delete the widget but hides it. To add the widget again, you must call both the addWidget() and show() functions.

slot

Hides the normal status indications and displays the given message for the specified number of milli-seconds ({timeout}). If {timeout} is 0 (default), the {message} remains displayed until the clearMessage() slot is called or until the showMessage() slot is called again to change the message.

Note that showMessage() is called to show temporary explanations of tool tip texts, so passing a {timeout} of 0 is not sufficient to display a \l{permanent message}{permanent message}.
