TTreeNode.GetNext Method

Returns the next node after the calling node in the tree view.

Pascal

function GetNext: TTreeNode;

C++

__fastcall TTreeNode GetNext();

Description

If the calling node is the last node, GetNext returns nil (Delphi) or NULL (C++). Otherwise, it returns the next node including nodes that aren't visible and child nodes. To get the next node at the same level as the calling node, use GetNextSibling. To get the next visible node, use GetNextVisible.

C++ Examples:

Copy Code

/*
The following example adds the Text for all items in the
tree view to the list box.  This example requires a ListBox
and a populated TreeView.
*/
void __fastcall TForm1::FormCreate(TObject *Sender)
{
  TTreeNode *CurItem = TreeView1->Items->GetFirstNode();
  while (CurItem)
  {
    ListBox1->Items->Add(CurItem->Text);
    CurItem = CurItem->GetNext();
  }

Delphi Examples:

Copy Code

{
The following example adds the Text for all items in the
tree view to the list box.  This example requires a ListBox
and a populated TreeView.
} 
procedure TForm1.FormCreate(Sender: TObject);
var
  CurItem: TTreeNode;
begin
  CurItem := TreeView1.Items.GetFirstNode;
  while CurItem <> nil do
  begin
    ListBox1.Items.Add(CurItem.Text);
    CurItem := CurItem.GetNext;
  end;
end;
