Description
The following example demonstrates how to add nodes and child nodes to a TTreeView control.
Code
void __fastcall TForm1::Button1Click(TObject *Sender)
{
TTreeNode *Node1;
TreeView1->Items->Clear(); // Remove any existing nodes.
// Add a root node.
TreeView1->Items->Add(NULL, "RootNode1");
/* Set MyTreeNode to the first node in the tree view and add a child node to it. */
Node1 = TreeView1->Items->Item[0];
TreeView1->Items->AddChild(Node1,"ChildNode1");
// Add another root node.
TreeView1->Items->Add(Node1, "RootNode2");
/* Reset Node1 to RootNode2 and add a child node to it. */
Node1 = TreeView1->Items->Item[2];
TreeView1->Items->AddChild(Node1,"ChildNode2");
/* Reset Node1 to ChildNode2 and add a child node to it. */
Node1 = TreeView1->Items->Item[3];
TreeView1->Items->AddChild(Node1,"ChildNode2a");
/* Add another child to ChildNode2, following ChildNode2a. */
TreeView1->Items->AddChild(Node1,"ChildNode2b");
// Add another root node.
TreeView1->Items->Add(TreeView1->Items->Item[0], "RootTreeNode3");
}
