Question

我正在尝试集成QWebEngineView小部件，该小部件在QTabWidget页面中作为单独的进程（QProcess）运行。到目前为止，QWebEngineView进程正在正常启动，但它在单独的窗口中显示网页，而不是在MainWindow应用程序的QTabWidget中显示它。

这是添加到QTabWidget的Widget。

BrokersTerminal.h



class BrokersTerminal : public QWidget
{
    Q_OBJECT

  public:
    explicit BrokersTerminal(QWidget *parent = 0);
    ~BrokersTerminal();

    void startTerminal();

  public slots:
    void brokersTerminalStarted();

  private:
    Ui::BrokersTerminal *ui;
    QProcess *brokers_process;
    QString brokers_program_path;
    QStringList arguments;
};


BrokersTerminal.cpp

BrokersTerminal::BrokersTerminal(QWidget *parent) :
  QWidget(parent),
  ui(new Ui::BrokersTerminal)
{
  ui->setupUi(this);
  brokers_process = new QProcess( this );
  brokers_program_path = QApplication::applicationFilePath();

  arguments << "--b";

  connect( brokers_process, &QProcess::started, this , &BrokersTerminal::brokersTerminalStarted );
}

BrokersTerminal::~BrokersTerminal()
{
  delete ui;
}

void BrokersTerminal::startTerminal()
{
  brokers_process->start( brokers_program_path, arguments );
  brokers_process->waitForStarted();
}

void BrokersTerminal::brokersTerminalStarted()
{
  qDebug() << "Brokers terminal started";
}

这是负责显示经纪人网站的WebView Widget。

BrokersWebWidget.h

class BrokersWebWidget : public QWidget
{
    Q_OBJECT

  public:
    explicit BrokersWebWidget(QWidget *parent = 0);
    ~BrokersWebWidget();

  private:
    Ui::BrokersWebWidget *ui;
    QUrl brokers_url;
    QWebEngineView *web_browser;
};

BrokersWebWidget.cpp

BrokersWebWidget::BrokersWebWidget(QWidget *parent) :
  QWidget(parent),
  ui(new Ui::BrokersWebWidget)
{
  ui->setupUi(this);

  brokers_url = "https://siteofbrokersapi.com/";

  web_browser = new QWebEngineView( this );
  web_browser->load( brokers_url );
}

BrokersWebWidget::~BrokersWebWidget()
{
  delete ui;
}

现在这个BrokersWebWidget作为一个单独的进程正常启动，但它在一个单独的窗口中打开，但是如何在BrokersTerminal Widget中添加它？

请告诉我任何可能的解决方案。感谢。

您无法将在一个进程中运行的窗口小部件嵌入到另一个窗口中运行的窗口中。 QWidget只能用于同一进程中在GUI线程中运行的小部件。

在QTabWidget中嵌入QWebEngineView进程
