Member Function Documentation
◆ data()
|
overridevirtual |
Return data associated with the item.
Must be implemented in derived class.
Implements QgsLayerTreeModelLegendNode.
Definition at line 625 of file qgslayertreemodellegendnode.cpp.
◆ drawSymbol()
|
overridevirtual |
Draws symbol on the left side of the item.
- Parameters
-
settings Legend layout configuration ctx Context for rendering - may be null if only doing layout without actual rendering itemHeight Minimal height of the legend item - used for correct positioning when rendering
- Returns
- Real size of the symbol (may be bigger than "normal" symbol size from settings)
Reimplemented from QgsLayerTreeModelLegendNode.
Definition at line 640 of file qgslayertreemodellegendnode.cpp.
◆ invalidateMapBasedData()
|
overridevirtual |
Notification from model that information from associated map view has changed.
Default implementation does nothing.
Reimplemented from QgsLayerTreeModelLegendNode.
Definition at line 716 of file qgslayertreemodellegendnode.cpp.
