Window.SourceInitialized事件何时引发 [英] When is the Window.SourceInitialized event raised

问题描述

我可以保证在Window.Loaded事件之前总是引发Window.SourceInitialized事件吗? 我需要HwndSource对象在我的 Window.Loaded事件处理程序中进行进一步处理，但是我不确定到那时是否总是可用

Can I guarantee the Window.SourceInitialized event will always be raised before the Window.Loaded event? I need the HwndSource object for further processing in my Window.Loaded event handler and I'm not sure if this will always be available by then

推荐答案

以下是您可以预期的事件序列(应该在加载之前发生):

Here's the sequence of events you can expect (it should occur before Loaded):

如果您要仔细检查，或者不信任获取SourceInitialized事件...那么您可以尝试自己获取HwndSource ...以查看其是否已连接.

If you want to double-check, or don't trust getting the SourceInitialized event...then you can try and obtain the HwndSource yourself....to see if it's connected.
