IWebBrowser2控件中的Tab键支持 [英] Tab key support in an IWebBrowser2 control

问题描述

我有一个嵌入的IWebBrowser2控件，它使用直接的C ++(带窗口的而不是没有窗口的)，当有人按下Tab键在浏览器中的各个字段之间移动时，它将焦点从Web浏览器中移出.

I have an embedded IWebBrowser2 control using straight C++ (windowed, not windowless) and when someone hits the Tab key to go between fields in the browser, it jumps focus out of the web browser.

关于我需要实现什么或可能搞砸了什么的任何想法?

Any ideas on what I need to implement or what I could be screwing up?

谢谢！

推荐答案

诸如tab的加速键是在分发之前由消息循环处理的.因此，挂钩函数需要由消息循环调用- IOleInPlaceActiveObject :: TranslateAccelerator iirc. -使控件有机会进行键盘导航输入.

Accelerator keystrokes like tab are handled by the message loop before being dispatched. As such a hook function needs to be called by a message loop - IOleInPlaceActiveObject::TranslateAccelerator iirc. - to give the control the chance to do keyboard navigation type things.
