Detailed Description

A proxy widget for QStatusBar.

Unlike QStatusBar, QgsStatusBar allows finer control of widget placement, including the option to locate permanent widgets on the left side of the bar.

QgsStatusBar is designed to be embedded into an existing window's QStatusBar, as a permanent widget. This allows reuse of the special QStatusBar handling for resize grips and other platform specific status bar tweaks.

Instead of adding child widgets and showing messages directly in the window's status bar, these widgets (and messages) should instead be added into the embedded QgsStatusBar.

Since: QGIS 3.0

Member Function Documentation

◆ addPermanentWidget()

void QgsStatusBar::addPermanentWidget	(	QWidget *	widget,
		int	stretch = `0`,
		Anchor	anchor = `AnchorRight`
	)

Adds the given widget permanently to this status bar, reparenting the widget if it isn't already a child of this 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 anchor parameter controls which side of the status bar the widget should be anchored to.
