c# 鼠标控制图片大小
首先在窗体构造方法,里加入这样一句话
- this.MouseWheel += new System.Windows.Forms.MouseEventHandler(this.panel1_MouseWheel);
- #region 进入窗体时加载
- public FormAlarmInfoQuery()
- {
- InitializeComponent();
- pictureBox1.ImageLocation = "f:\\1.jpg";
- this.MouseWheel += new System.Windows.Forms.MouseEventHandler(this.panel1_MouseWheel);
- //判断是否已安装带滚轮的鼠标
- //SystemInformation.MouseWheelPresent.ToString();
- //获取鼠标滚轮在滚动时所获得的行数
- //SystemInformation.MouseWheelScrollLines.ToString();
- //判断该操作系统是否支持滚轮鼠标
- //SystemInformation.NativeMouseWheelSupport.ToString();
- }
- #endregion
然后写一个鼠标事件方法
- private void panel1_MouseWheel(object sender, System.Windows.Forms.MouseEventArgs e)
- {
- MessageBox.Show("滚动事件已被捕捉");
- System.Drawing.Size t = pictureBox1.Size;
- t.Width += e.Delta;
- t.Height += e.Delta;
- pictureBox1.Width = t.Width;
- pictureBox1.Height = t.Height;
- }
如果输出了“滚动事件已被捕捉”,那么鼠标滚轮事件就成功被捕捉了,就可以在在里边写让鼠标滚轮处理的事件了
