In .NET 4.0 WPF, how do you detect a double-click by the left mouse button?

一个看似简单的任务。

我不明白确定哪个按钮是$ P $使用 System.Windows.Input pssed在 MouseDoubleClick 事件的方式。 MouseButtonEventArgs 。

I don't see a way of determining which button was pressed in the MouseDoubleClick event using the System.Windows.Input.MouseButtonEventArgs.

推荐答案

MouseDoubleClick 通过 MouseButtonEventArgs 作为事件参数。这暴露了<一href="http://msdn.microsoft.com/en-us/library/system.windows.input.mousebuttoneventargs.changedbutton.aspx">ChangedButton属性，它会告诉你哪个按钮被点击双击

MouseDoubleClick passes MouseButtonEventArgs as the event arguments. This exposes the ChangedButton property, which tells you which button was double clicked.

void OnMouseDoubleClick(Object sender, MouseButtonEventArgs e)
{
    if (e.ChangedButton == MouseButton.Left)
    {
        // Left button was double clicked
    }
}
