class qgis.gui.QgsDataDefinedSizeLegendWidget[source]¶

Bases: QgsPanelWidget

__init__(ddsLegend: QgsDataDefinedSizeLegend | None, ddSize: QgsProperty, overrideSymbol: QgsMarkerSymbol | None, canvas: QgsMapCanvas | None = None, parent: QWidget | None = None)

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.

Parameters:

ddsLegend (Optional[QgsDataDefinedSizeLegend])
ddSize (QgsProperty)
overrideSymbol (Optional[QgsMarkerSymbol])
canvas (Optional[QgsMapCanvas] = None)
parent (Optional[QWidget] = None)

dataDefinedSizeLegend(self) → QgsDataDefinedSizeLegend | None[source]¶

Returns configuration as set up in the dialog (may be None). Ownership is passed to the caller.

Return type:: Optional[QgsDataDefinedSizeLegend]
