如何实现伪双击事件

大体都是用两次单击的时间差来判断一下是否是双击。

SystemInformation.DoubleClickTime默认是500

第一种方式：可以参考http://blog.csdn.net/zbssoft/article/details/5602658

 DateTime   lastDownTime   =   DateTime.Now;   
  private   void   comboBox1_MouseDown(object   sender,   MouseEventArgs   e)   
  {   
  TimeSpan   sp   =   DateTime.Now   -   lastDownTime;   
  if   (sp.Milliseconds   <=   SystemInformation.DoubleClickTime)   
  {   
  System.Console.WriteLine("DoubleClick");   
  }   
  else   
  {   
  System.Console.WriteLine("Click");   
  }   
  lastDownTime   =   DateTime.Now;   
  }  

 

Derexpress中的TreeList控件触发双击事件的时候，总会触发单击事件。为了处理单击和双击的时候分别处理不同的代码，解决方案如何：

第二种方式：http://www.devexpress.com/Support/Center/p/S136873.aspx。记得是在Timer控件的Interval 属性为500

bool needHandleMouseClick = true;
        private void tlDokumente_MouseClick(object sender, MouseEventArgs e)  {
            timer1.Start();
        }

        private void treeList1_MouseDoubleClick(object sender, MouseEventArgs e) {
            needHandleMouseClick = false;
            // perform your code here
            //...
            //System.Diagnostics.Process.Start(file);
        }

        private void timer1_Tick(object sender, EventArgs e)    {
            timer1.Stop();
            if (needHandleMouseClick)   {
                // your code here
                //...
                // wbDokument.Navigate(file);
            }
            needHandleMouseClick = true;
        }
