Создайте HTML-страницу в Qt и сохраните ее в формате PDF.

Сообщение Anonymous » 23 май 2024, 12:58

Я пытаюсь создать файл HTML с помощью Qt C++, а затем сохранить его в файл PDF. На данный момент мне удалось создать файл HTML, но когда я пытаюсь сохранить его в файл PDF, я получаю предупреждение D3D11 Live Object в моей консоли, и файл PDF не будет создан.
Я посмотрел так много решений на форуме, и я попробовал их все, но, похоже, это не работает, может быть, я что-то недосмотрел?
РЕДАКТИРОВАТЬ: я запускаю свой код в режиме отладки! В режиме выпуска это действительно работает... почему?!!!
Вот мой код:
MainWindow.cpp

{
ui->setupUi(this);

createHtmlFile(); // Create the HTML file

view = new QWebEngineView(this);
connect(view, &QWebEngineView::loadFinished, this, &MainWindow::onLoadFinished);

QString htmlFilePath = QCoreApplication::applicationDirPath() + "/index.html"; //Returns the directory that contains the application executable
