Member Function Documentation

◆ createLayerTreeModelLegendNodes()

virtual QList<QgsLayerTreeModelLegendNode *> QgsMapLayerLegend::createLayerTreeModelLegendNodes ( QgsLayerTreeLayer * nodeLayer )

pure virtual

Return list of legend nodes to be used for a particular layer tree layer node.

Ownership is transferred to the caller.

◆ defaultVectorLegend()

QgsMapLayerLegend * QgsMapLayerLegend::defaultVectorLegend ( QgsVectorLayer * vl )

static

Create new legend implementation for vector layer.

Definition at line 33 of file qgsmaplayerlegend.cpp.

◆ itemsChanged

void QgsMapLayerLegend::itemsChanged ( )

signal

Emitted when existing items/nodes got invalid and should be replaced by new ones.
