最近要把 POS 程式改成無鍵盤的觸控螢幕操作 , 所以所有的功能鍵都要做在螢幕上 , 但在商品銷售時要藏起來 , 無意間看見朋友的 iPhone 的滑動菜單效果 , 想說何不來模擬這種效果 , 當收銀員需要選單時 , 只要把手指在 this.panel1.Controls.Add(this.pictureBox1);
this.panel1.Location = new System.Drawing.Point(306, 1);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(336, 495);
