Constructor & Destructor Documentation

◆ QgsLayoutColumnSourceDelegate()

QgsLayoutColumnSourceDelegate::QgsLayoutColumnSourceDelegate	(	QgsVectorLayer *	vlayer,
		QObject *	parent = `nullptr`,
		const QgsLayoutObject *	layoutObject = `nullptr`,
		bool	forceExpressions = `false`
	)

Constructor for QgsLayoutColumnSourceDelegate.

If forceExpressionValues is true then the values generated by the delegate will always be complete QGIS expressions, i.e. field references will be quoted accordingly.
