房租管理小软件（七）：flowlayoutPancel 中增加分类控

见下图的

                 string FNodeName = dt.Rows[i]["FNodeName"].ToString();
                 if (i == )
                 {
                     RoomControl.Thumbnail.GroupItem gItem = new GroupItem();
                     gItem.Size = new Size(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width-, gItem.Size.Height);//需要把分类的迟寸设成，

                     gItem.labelControl1.Text = FNodeName;
                     //v.Take(1).Single().
                     this.thumbnailFlowLayoutPanel1.Controls.Add(gItem);
                     this.thumbnailFlowLayoutPanel1.SetFlowBreak(gItem, true);
                 }
