Layer tree group node serves as a container for layers and further groups.
void writeXml(QDomElement &parentElement, const QgsReadWriteContext &context) override
Write group (tree) as XML element <layer-tree-group> and add it to the given parent element.
QgsLayerTreeGroup * clone() const override
Returns a clone of the group.
static QgsLayerTreeGroup * readXml(QDomElement &element, const QgsReadWriteContext &context)
Read group (tree) from XML element <layer-tree-group> and return the newly created group (or nullptr ...
Layer tree node points to a map layer.
This class is a base class for nodes in a layer tree.
@ NodeGroup
Container of other groups and layers.
@ NodeLayer
Leaf node pointing to a layer.
NodeType nodeType() const
Find out about type of the node. It is usually shorter to use convenience functions from QgsLayerTree...
Namespace with helper functions for layer tree operations.
static QgsLayerTreeLayer * toLayer(QgsLayerTreeNode *node)
Cast node to a layer.
static bool isLayer(const QgsLayerTreeNode *node)
Check whether the node is a valid layer node.
static const QgsLayerTreeLayer * toLayer(const QgsLayerTreeNode *node)
Cast node to a layer.
static bool isGroup(QgsLayerTreeNode *node)
Check whether the node is a valid group node.
static QgsLayerTreeGroup * toGroup(QgsLayerTreeNode *node)
Cast node to a group.
The class is used as a container of context for various read/write operations on other objects.
QList< QgsWeakMapLayerPointer > QgsWeakMapLayerPointerList
A list of weak pointers to QgsMapLayers.
