在Winform的窗体中，存在背景图的情况下，不想在画面上加入按钮，只希望利用窗体自身的几个事件来实现按钮按下的效果，怎么样实现呢？ 其实这也不难，只需要按照下列步骤即可实现，首先确定要按下的几个区域的坐标点和大小，准备好按下和弹出的图片，将这些坐标点和大小 组成一个个区域（使用GraphicsPath来完成）。然后使用几个Flage标志，标识是否区域的按下。具体实现的代码如下： /// <summary> /// 实时监控，酒位展示，酒柜介绍，网络订购4个按钮的位置参数 /// </summary> int[,] BtnLocation = new int[4, 2]{{637,161},{683,269},{714,374},{637,478}}; /// <summary> /// 4个按钮的Size参数 /// </summary> Size BtnSize = new Size(285,92); /// <summary> /// 实时监控按钮是否按下的标志 /// </summary> bool FlageMouseDownRealTime = false; /// <summary> /// 酒位展示按钮是否按下的标志 /// </summary> bool FlageMouseDownWinePos = false; /// <summary> /// 酒柜介绍按钮是否按下的标志 /// </summary> bool FlageMouseDownCupIntrol = false; /// <summary> /// 网络订购按钮是否按下的标志 /// </summary> bool FlageMouseDownNetPurchase = false; /// <summary> /// 实时监控按钮的位置范围 /// </summary> GraphicsPath gpRealTime = new GraphicsPath(); /// <summary> /// 酒位展示按钮的位置范围 /// </summary> GraphicsPath gpWinePos = new GraphicsPath(); /// <summary> /// 酒柜介绍按钮的位置范围 /// </summary> GraphicsPath gpCupIntrol = new GraphicsPath(); /// <summary> /// 网络订购按钮的位置范围 /// </summary> GraphicsPath gpNetPurchase = new GraphicsPath(); Graphics dc = null; /// <summary> /// 获取4个按钮的区域范围 /// </summary> private void GetButtonGraphicPath() { FlageMouseDownRealTime = false; FlageMouseDownWinePos = false; FlageMouseDownCupIntrol = false; FlageMouseDownNetPurchase = false; Point[] pt = new Point[]{ new Point(BtnLocation[0,0],BtnLocation[0,1]), new Point(BtnLocation[0,0]+BtnSize.Width,BtnLocation[0,1]), new Point(BtnLocation[0,0]+BtnSize.Width,BtnLocation[0,1]+BtnSize.Height), new Point(BtnLocation[0,0],BtnLocation[0,1]+BtnSize.Height) }; gpRealTime.AddLines(pt); pt = new Point[]{ new Point(BtnLocation[1,0],BtnLocation[1,1]), new Point(BtnLocation[1,0]+BtnSize.Width,BtnLocation[1,1]), new Point(BtnLocation[1,0]+BtnSize.Width,BtnLocation[1,1]+BtnSize.Height), new Point(BtnLocation[1,0],BtnLocation[1,1]+BtnSize.Height) }; gpWinePos.AddLines(pt); pt = new Point[]{ new Point(BtnLocation[2,0],BtnLocation[2,1]), new Point(BtnLocation[2,0]+BtnSize.Width,BtnLocation[2,1]), new Point(BtnLocation[2,0]+BtnSize.Width,BtnLocation[2,1]+BtnSize.Height), new Point(BtnLocation[2,0],BtnLocation[2,1]+BtnSize.Height) }; gpCupIntrol.AddLines(pt); pt = new Point[]{ new Point(BtnLocation[3,0],BtnLocation[3,1]), new Point(BtnLocation[3,0]+BtnSize.Width,BtnLocation[3,1]), new Point(BtnLocation[3,0]+BtnSize.Width,BtnLocation[3,1]+BtnSize.Height), new Point(BtnLocation[3,0],BtnLocation[3,1]+BtnSize.Height) };
