Constructor & Destructor Documentation

◆ QgsMapLayerLegend()

QgsMapLayerLegend::QgsMapLayerLegend ( QObject parent = nullptr)
explicit

Definition at line 29 of file qgsmaplayerlegend.cpp.

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.

◆ defaultPluginLegend()

QgsMapLayerLegend * QgsMapLayerLegend::defaultPluginLegend ( QgsPluginLayer pl)
static

Create new legend implementation for raster layer.

Definition at line 44 of file qgsmaplayerlegend.cpp.

◆ defaultRasterLegend()

QgsMapLayerLegend * QgsMapLayerLegend::defaultRasterLegend ( QgsRasterLayer rl)
static

Create new legend implementation for raster layer.

Definition at line 39 of file qgsmaplayerlegend.cpp.

◆ defaultVectorLegend()

QgsMapLayerLegend * QgsMapLayerLegend::defaultVectorLegend ( QgsVectorLayer vl)
static

Create new legend implementation for vector layer.

Definition at line 34 of file qgsmaplayerlegend.cpp.

◆ itemsChanged

void QgsMapLayerLegend::itemsChanged ( )
signal

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