QWebView/QWebPage 是在单独的线程中还是在主/gui 线程中下载内容？

如果没有，那么我如何显式强制它在单独的线程中异步下载？

根据文档 QWebView::setHtml()：

Sets the content of the web view to the specified html.
External objects such as stylesheets or images referenced in the HTML document are located relative to baseUrl.
The html is loaded immediately; external objects are loaded asynchronously.

QWebView::setContent() 也是如此。因此，原始 HTML 在主线程中加载，任何其他引用（图像、样式表等）在单独的线程中异步加载。

根据经验，我可以看出 QWebView::setUrl() 也异步加载，使用网络管理器等待原始 HTML，这将依次加载其他引用，也是异步的。据我所知，没有办法强制QWebView同步动作。

According to the documentation for QWebView::setHtml():

Sets the content of the web view to the specified html.
External objects such as stylesheets or images referenced in the HTML document are located relative to baseUrl.
The html is loaded immediately; external objects are loaded asynchronously.

Same thing goes for QWebView::setContent(). Therefore, the raw HTML is loaded in the main thread, and any other references (images, stylesheets, etc.) are loaded asynchronously in a separate thread.

From experience, I can tell that QWebView::setUrl() also loads asynchronously, using a network manager to wait for the raw HTML, which will in turn load the other references, also asynchronously. As far as I know, there is no way to force QWebView to act sychcronously.
