Class: QgsDataDefinedSizeLegendWidget

class qgis.gui.QgsDataDefinedSizeLegendWidget(ddsLegend: QgsDataDefinedSizeLegend, ddSize: QgsProperty, overrideSymbol: QgsMarkerSymbol, canvas: QgsMapCanvas = None, parent: QWidget = None)

Bases: QgsPanelWidget

Creates the dialog and initializes the content to what is passed in the legend configuration (may be None). The ddSize argument determines scaling of the marker symbol - it should have a size scale transformer assigned to know the range of sizes. The overrideSymbol argument may override the source symbol: this is useful in case when the symbol is given from outside rather than being set inside QgsDataDefinedSizeLegend.

Widget for configuration of appearance of legend for marker symbols with data-defined size.

New in version 3.0.
