Returns an object handle to the first child, zero if none
Function FirstChild Returns Handle
Call: | Get FirstChild to HandleVariable |
FirstChild finds the first child of a node and returns a handle to it. The message is sent to the parent node. It is often used with NextNode to traverse all child nodes.
Get FirstChild of hoRoot to hoNode // get the first node While (hoNode<>0) Send ShowInformation hoNode Get NextNode of hoNode to hoNode // now get next sibling node Loop
The NextSibling message can also be used to find the next sibling node (and not destroy the current node). NextNode is usually preferred.
Get FirstChild of hoRoot to hoNode // get the first node While (hoNode<>0) Send ShowInformation hoNode Get NextSibling of hoNode to hoNextNode // now get next sibling node Send Destroy of hoNode // Important: get rid of the previous node object Move hoNextNode to hoNode LoopSee Also
