使用的是以上popup来模拟模态对话框,如何实现点击非popup窗体区域时，popup高亮闪烁效果,即实现MessageBox.Show()点击非MessageBox区域时MessageBox高亮闪烁。

原先使用的var window = new Window();
            window.Owner = this;
            window.ShowDialog();来实现的弹出窗体效果，后发现该方法会多1个进程,故放弃.

暂时没有找到好的办法，采用了telerik的RadWindow作为弹出框架.

原先是想实现一个弹出窗口类似于MessageBox的模态效果,如点击MessageBox外面是，程序整个窗口会高亮显示等。具体效果可以自己写个demo弹出个MessageBox,看下。
