然后回到OutofbrowserMainPage页面,这里,我们在“关于”按钮上,添加Click事件响应,使其被点击后,d出Notifications窗口。
首先创建notifyWindow实例,
1 #region Private Members
2 Window OOBWindow = Application.Current.MainWindow;
3 NotificationWindow notifyWindow = null ;
4 #endregion
5
6 #region Constructor
7 public OutofbrowserMainPage()
8 {
9 InitializeComponent();
10 notifyWindow = new NotificationWindow();
11
12
13 }
14 #endregion
然后在Click事件中进行窗口激活:
1 private voID aboutBtn_Click( object sender, RoutedEventArgs e)2 {
3 if ( null == notifyWindow)
4 MessageBox.Show( " 通告窗口仅能运行在OOB模式下,请安装Silverlight应用到本地。 " );
5
6 if ( true == App.Current.IsRunningOutOfbrowser)
7 {
8 if (notifyWindow.Visibility == Visibility.Visible)
9 notifyWindow.Close();
10
11 NotificationControl myNotify = new NotificationControl();
12 notifyWindow.WIDth = 300 ;
13 notifyWindow.Height = 100 ;
14 notifyWindow.Content = myNotify;
15 notifyWindow.Show( 10000 );
16 }
17
18 }
在上面代码中,我们创建了一个新的Notification窗口实例,然后使用Show(毫秒),使其显示在客户端,最终显示效果如下:
今天的内容暂时到这里了,下一篇,我们将综合使用这些Silverlight OOB应用开发技巧实现一个完整应用实例, Silverlight Out of browser音乐播放器。
