webbrowser无法响应快捷键、按键消息

添加到对话框里的webbrowser无法响应键盘的按键消息，如：回车、快捷键、tab等

 

网上找到了个简单的方法：http://www.codeproject.com/KB/wtl/wtl4mfc6.aspx

 

方法在“Keyboard Handling”这一节，翻译过来就是：

 

问题原因：对话框使用IsDialogMessage来处理了所有的键盘消息，这样webbrowser就无法得到响应的键盘消息了

 

解决方法：在对话框的PreTranslateMessage里发送WM_FORWARDMSG消息，普通的窗口因无法识别这个消息而自动忽略，但是获得焦点(has the focus)的ActiveX控件能正确识别这个消息并看看是否要对这个消息进行处理

 

代码：

BOOL CMainDlg::PreTranslateMessage(MSG* pMsg) { // This was stolen from an SDI app using a form view. // // Pass keyboard messages along to the child window that has the focus. // When the browser has the focus, the message is passed to its containing // CAxWindow, which lets the control handle the message. if((pMsg->message < WM_KEYFIRST || pMsg->message > WM_KEYLAST) && (pMsg->message < WM_MOUSEFIRST || pMsg->message > WM_MOUSELAST)) return FALSE; HWND hWndCtl = ::GetFocus(); if(IsChild(hWndCtl)) { // find a direct child of the dialog from the window that has focus while(::GetParent(hWndCtl) != m_hWnd) hWndCtl = ::GetParent(hWndCtl); // give control a chance to translate this message if(::SendMessage(hWndCtl, WM_FORWARDMSG, 0, (LPARAM)pMsg) != 0) return TRUE; } // A normal control has the focus, so call IsDialogMessage() so that // the dialog shortcut keys work (TAB, etc.) return IsDialogMessage(pMsg); }  

 

这个是wtl代码，mfc的应该也差不多

添加这个代码后webbrowser里的回车、tab、快捷键都能正常响应了
