silverlight鼠标双击2

网友做的一个双击的例子

原理是

第一次点击 开一个线程(sheep 200 且 lock)

如果在200ms内再点击 线程继续sheep 200 统计点击次数

...........

............

timeout 后

线程执行 比较传入的要求点击数与统计点击的次数

true 的话就执行

public class MClick

{

public static void MulClick(int count, MouseButtonEventHandler handle, object sender, MouseButtonEventArgs e)

{

bolClicking = true;

if (bolClicked)

{

intClickCount++;

}

else

{

bolClicked = true;

intCount = count;

handleClick = handle;

objSender = sender;

mbeE = e;

asyncOperation = AsyncOperationManager.CreateOperation(null);

objThreadLock = new object();

Thread thread = new Thread(ResetThread);

thread.Start();

while (!thread.IsAlive) ;

}

}

private static int intTimeOut = 200;

public static int TimeOut

{

get

{

return intTimeOut;

}

set

{

intTimeOut = value < 1 ? 1 : value;

}

}

private static int intCount;

private static object objSender;

private static MouseButtonEventArgs mbeE;

private static MouseButtonEventHandler handleClick;

private static int intClickCount = 0;

private static bool bolClicked = false;

private static bool bolClicking = false;

private static object objThreadLock;

private static AsyncOperation asyncOperation;

private static void ResetThread()

{

while (bolClicking)

{

bolClicking = false;

Thread.Sleep(TimeOut);

}

lock(objThreadLock)

{

if (intCount == ++intClickCount)

{

asyncOperation.Post(callback, objSender);

}

intClickCount = 0;

bolClicked = false;

}

}

private static void callback(object state)

{

handleClick(objSender, mbeE);

}

}

============================

只是测试性，满乱的~~哈哈。有兴趣的朋友可以改进~

改成

MulClick(点击次数, 控件, 函数)

使用

==============================

public Page()

{

InitializeComponent();

LayoutRoot.MouseLeftButtonUp += new MouseButtonEventHandler(HandleClick);

}

private void HandleClick(object sender, MouseButtonEventArgs e)

{

//MClick.MulClick(1, onClick, sender, e);

MClick.MulClick(2, onDoubleClick, sender, e);

}

private void onClick(object sender, MouseButtonEventArgs e)

{

txtMsg.Text = "单击";

}

private void onDoubleClick(object sender, MouseButtonEventArgs e)

{

txtMsg.Text = "双击";

}

}
