为什么WPF ListBox.ListItems不会引发MouseRightButtonDown

Question

我正在尝试RoutedEvent来自WPF 4的例子Unleashed book。该示例在Window上有许多控件，并且它在窗口上定义了MouseRightButtonDown以在窗口的标题栏中显示事件源。 所以当我们右键单击窗口的任何子元素时，它的名称，类型等都显示在窗口的标题栏中。但是，当我右键单击ListBox的ListItem时，它不会在窗口的标题栏中设置它的名称，标题等。为什么？

的代码如下：

XAML

<Window x:Class="TempWPFProj.RoutedEventDemo" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="About WPF 4 Unleashed" 
     SizeToContent="WidthAndHeight" 
     Background="OrangeRed" MouseRightButtonDown="Window_MouseRightButtonDown"> 
    <StackPanel> 
     <Label FontWeight="Bold" FontSize="20" Foreground="White">

      <ListBoxItem>Chapter 2</ListBoxItem> 
     </ListBox> 
     <StackPanel Orientation="Horizontal" HorizontalAlignment="Center"> 
      <Button MinWidth="75" Margin="10">Help</Button> 
      <Button MinWidth="75" Margin="10">OK</Button> 
     </StackPanel> 
     <StatusBar>You have successfully registered this product.</StatusBar> 
    </StackPanel> 
</Window>

它说，就在这本书为什么在列表框中没有为工作点击右键

“当您右键单击任一ListBoxItem时，窗口永远不会收到MouseRightButtonDown事件。这是因为ListBoxItem的内部处理这一事件以及MouseLeftButtonDown事件（停止冒泡）实施项目选择”
