Question

我的BB 10级联中有一个套接字连接App，当套接字连接关闭时，我需要显示一个对话框，当按下OK按钮时，需要关闭。

请在这里找到我的代码......

void SocketBase::writeLine(QTcpSocket *socket, const QString &line)
{
if (socket->state() != QAbstractSocket::ConnectedState)
{
       onOkAlert("Please check your internet connection and restart the app again");
}
}

void SocketBase :: onOkAlert（const QString＆amp; message） {

dialog = new SystemDialog(tr("OK"), 0); 
dialog->setTitle(tr("Alert")); 
dialog->setBody(message); 

 bool success=      QObject::connect(dialog,SIGNAL(finished(bb::system::SystemUiResult::Type)),
                        this,
                SLOT(onDialogFinishe(bb::system::SystemUiResult::Type)));
 if(success){
 dialog->show();
}

}

我还在课堂上添加了

using namespace bb::data;
using namespace bb::cascades;
using namespace bb::system;
SystemDialog *dialog;

我的socketBase.h就像，

    class SocketBase: public QObject{
     Q_OBJECT
    public:
SocketBase(const QString &ipAddr, const ushort port) :
        mIP(ipAddr), mPort(port) {
    mRunThread = false;
}
enum Identity {
    BAD_IDENTITY, SERVER, CLIENT
};
virtual void startThread() = 0;
virtual void stopThread() = 0;
virtual Identity getIdentity() = 0;
 Q_INVOKABLE void showDialog(int id);
 void onOkAlert(const QString &message);

 private slots:
     void onAPPFinished();
     void onDialogFinishe(bb::system::SystemUiResult::Type);
     }

这是应用终止代码

 void SocketBase::onDialogFinishe(bb::system::SystemUiResult::Type)
{
qDebug()<<" dialog->result():::"<<dialog->result();
    if(dialog->result()==2)
    {
        qDebug()<<"::: Terminate App :::";
        bb::Application::exit(0);
    }

}

我的代码有什么问题，请帮助!!!

按下警报按钮，终止BB 10应用程序
