我如何确定一个WPF窗口模式？ [英] How do I determine if a WPF window is modal?

问题描述

什么是找出最简单的方法，如果一个窗口模态还是不开？

What's the easiest way to figure out if a window is opened modally or not?

CLARIFIACTION： 我打开一个窗口，调用

CLARIFIACTION: I open a window calling

myWindow.ShowDialog();

我有一个OK和放一个页脚; 取消按钮，我只希望如果窗口打开模态展现。现在我知道我可以这样设置属性：

I have a footer with an "OK" & "Cancel" button that I only want to show if the window is opened modally. Now I realize I can set a property by doing this:

myWindow.IsModal = true;
myWindow.ShowDialog();

不过，我想这是自作出这样的决定的窗口。我要检查在该窗口的装事件是否是模式的。

But I want the window it's self to make that determination. I want to check in the "Loaded" event of the window whether or not it is modal.

更新 而IsModal属性没有的实际上的存在于一个WPF窗口。这是我创建了一个属性。的ShowDialog（）块中的当前线程。我猜我可以确定窗口是由若当前线程被阻塞检查通过的ShowDialog（）打开。我怎么会去这样做？

UPDATE The "IsModal" property doesn't actually exist in a WPF window. It's a property that I have created. ShowDialog() blocks the current thread. I'm guessing I can determine if the Window is opened via ShowDialog() by checking if the current thread is blocked. How would I go about doing that?

System.Windows.Interop.ComponentDispatcher.IsThreadModal可以告诉你，如果调用线程当前正在运行的模式HWND。的
