推荐答案

您是否出于任何特定原因需要 Widget 面板中的 QWebEngineView?您可以直接从代码中使用任何 Web 引擎小部件(尽管它当然不像拖放那样简单).举个简单的例子:

Do you need the QWebEngineView in the Widget palette for any specific reason? You can use any of the web engine widgets directly from code (although it is of course not as simple as a drag-and-drop). As a simple example:

#include <QWebEngineView>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QString url = "https://stackoverflow.com/";
    QWebEngineView view = new QWebEngineView(this);
    view->load(url);
    // Sets the webview to be the main window's central widget.
    setCentralWidget(view);
}

不确定这是否对您有任何帮助.如果您真的有兴趣在设计器中使用小部件，您可以尝试将其添加为自定义模块.看看以下链接:

Not sure if this helps you in any way. If you are really interested in having the widget in the designer, you can maybe try adding it as a custom module. Have a look at the following links:
