Attributes

addChildNode(self, node: QgsProcessingToolboxModelNode)¶: Adds a child node to this node, transferring ownership of the node to this node.

children(self) → object¶: Returns a list of children belonging to the node.

getChildGroupNode(self, id: str) → QgsProcessingToolboxModelGroupNode¶: Tries to find a child node belonging to this node, which corresponds to a group node with the given group id. Returns None if no matching child group node was found.

nodeType(self) → QgsProcessingToolboxModelNode.NodeType¶: Returns the node’s type.

parent(self) → QgsProcessingToolboxModelNode¶: Returns the node’s parent. If the node’s parent is a null pointer, then the node is a root node.

takeChild(self, node: QgsProcessingToolboxModelNode) → QgsProcessingToolboxModelNode¶: Removes the specified node from this node’s children, and gives ownership back to the caller.
