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.
