Qt Windows消息处理-热键注册

1.头文件,重写:

bool winEvent(MSG *msg, long *result);
2.注册热键:

    ::RegisterHotKey(this->winId(), 100,0, VK_F2);
3.处理Windows消息:

bool YYKengDieButton::winEvent(MSG *msg, long *result)
{
    if(msg->message==WM_HOTKEY)
    {
        if(msg->wParam==100)
            timer->stop();
    }
    return false;
}

4.重写关闭事件、卸载热键:


void YYKengDieButton::closeEvent(QCloseEvent *event)
{
    ::UnregisterHotKey(this->winId(),100);
}
