TreeView

[hduchan]

I check the Phantom Help,i find there has a function (Getcount( ) to get the value about the all elements).
For example,There has a parent node, may have two child nodes, each child node may have more nodes.so i don't wanna get all the number of the nodes.So when i click the parent node,so i wanna get the value of the child nodes,as i konw ,there are two child nodes,so i want to use the function to get the value '2'..what can i do?or what function can used in the treeView function..
