更改树视图节点颜色

不管怎样,API中有一条关于这一点的消息;

uses
  commctrl;

procedure TForm1.FormCreate(Sender: TObject);
begin
  SendMessage(TreeView1.Handle, TVM_SETLINECOLOR, 0, ColorToRGB(clYellow));
end;

也许您可以使用TTreeView的OnCustomDrawItem事件:

procedure TForm1.TreeView1CustomDrawItem(Sender: TCustomTreeView;
  Node: TTreeNode; State: TCustomDrawState; var DefaultDraw: Boolean);
begin
  with Sender as TCustomTreeView do
  begin
    Canvas.Brush.Color := clBlack;
    Canvas.Font.Color := clBlack
  end;
end;
