Hi,
I think, what you need is the following:
- {
- public:
- bool winEvent(MSG* message, long* result)
- {
- if(WM_KEYDOWN == message->message)
- {
- HWND hWndParent = ::GetParent(WinId());
- if(0 != hWndParent)
- *result = ::SendMessage(, message->message, message->lParam, message->wParam);
- }
- }
- }
Building the correct WPARAM for the WM_KEYDOWN event is not so easy, as it contains scan codes etc (WM_KEYDOWN on MSDN [msdn.microsoft.com]).aspx ). Make sure to also foreward the WM_KEYUP event. You could also just do a filtering before forewarding etc.
