| int | rowCount (const QModelIndex &parent=QModelIndex()) const override |
| void | setAutoCollapseLegendNodes (int nodeCount) |
| Set at what number of legend nodes the layer node should be collapsed. Setting -1 disables the auto-collapse (default). | |
| Q_DECL_DEPRECATED void | setAutoCollapseSymbologyNodes (int nodeCount) |
| void | setCurrentIndex (const QModelIndex ¤tIndex) |
| Set index of the current item. May be used by view. Item marked as current is underlined. | |
| bool | setData (const QModelIndex &index, const QVariant &value, int role=Qt::EditRole) override |
| void | setFlag (Flag f, bool on=true) |
| Enable or disable a model flag. | |
| void | setFlags (Flags f) |
| Set OR-ed combination of model flags. | |
| void | setLayerTreeNodeFont (int nodeType, const QFont &font) |
| Set font for a particular type of layer tree node. nodeType should come from QgsLayerTreeNode::NodeType enumeration. | |

| Force only display of legend nodes which are valid for given map settings. | |
| void | setLegendFilterByScale (double scaleDenominator) |
| Force only display of legend nodes which are valid for given scale denominator. | |
| void | setLegendMapViewData (double mapUnitsPerPixel, int dpi, double scale) |
| Give the layer tree model hints about the currently associated map view so that legend nodes that use map units can be scaled currectly. | |
| void | setRootGroup (QgsLayerTreeGroup *newRootGroup) |
| Reset the model and use a new root group node. | |
| Qt::DropActions | supportedDropActions () const override |
| bool | testFlag (Flag f) const |
