QWebInspector无法正常工作

Question

我已将QWebInspector包含在我的QT项目中，并尝试在我的代码中使用它（不清楚我是如何对QT还是一个新手）我得到一个空白的Web Inspector屏幕所以我认为页面（）正在返回空值？我哪里出错或者这只适用于HTML5应用程序？

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtGui>
#include <QSsl>
#include <QSslError>

    QMainWindow(parent),

    setWindowState(Qt::WindowMaximized);
    //MainWindow::showMaximized();
    this->centralWidget()->setLayout(new QGridLayout);
    m_pWebView = new QWebView(this);

    //Detect any SSL errors from the network reply
    connect(m_pWebView->page()->networkAccessManager(), SIGNAL(sslErrors(QNetworkReply*, const QList<QSslError> & )),
                    this, SLOT(onSslErrors(QNetworkReply*, const QList<QSslError> & )));

    this->centralWidget()->layout()->addWidget(m_pWebView);
    //set position and size
    m_pWebView->load(QUrl("https://csm.nathan"));




    //m_pWebView->show();

    QMenu *trayIconMenu;

       systray->setContextMenu (trayIconMenu);
       systray->show();
       if(systray->isVisible()){
           systray->showMessage("CytoViewer v1.0", "The CytoViewer has been started!", QSystemTrayIcon::NoIcon, 10000);

           //QMessageBox msgBox;
           //msgBox.setWindowTitle("HELP");
           //msgBox.setInformativeText(m_pWebView->page());
           //msgBox.exec();

           //Enable developer extras in the webviewer settings
           m_pWebView->page()->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
           //Instantiate QWebInspector
           QWebInspector inspector;

           inspector.setPage(m_pWebView->page());

           inspector.setVisible(false);
       }
