procedure TMainForm.UniFormCreate(Sender: TObject);
var
  I: Integer;
begin
  for I := UniPageControl1.PageCount -  downto  do // 一定是  downto 1
  begin
    UniPageControl1.Pages[I].Visible := false;
    UniPageControl1.Pages[I].TabVisible := false;
  end;
  UniPageControl1.ActivePageIndex:=;//设计 时， 一定要 先 首页 最先显示

UniTreeView1.FullExpand;

end;

procedure TMainForm.UniTreeView1Click(Sender: TObject);
