我不能说在使用 QWebView ，即使在相当弱的SBCs。我想知道是否还有其他事情正在减缓你的下降。

I can't say I've ever had any appreciable slowdown of the rest of a user interface when using QWebView, even on quite underpowered SBCs. I wonder if there's something else going on that's slowing you down.

您加载的所有网页，或只是某些网页时，是否会遇到此问题？

Are you getting this problem with all pages you load, or just certain ones?

可以访问设置对象（ QWebSettings $）的实例c $ c> ）为您的 QWebView 使用 QWebView :: settings（）。我建议禁用JS开始（ QWebSettings :: setAttribute（JavascriptEnabled，false）），只是为了看看你是否被任何脚本您尝试显示的页面。

One idea: you can access the settings object (an instance of QWebSettings) for your QWebView using QWebView::settings(). I'd recommend disabling JS to start with (QWebSettings::setAttribute(JavascriptEnabled, false)), just to see if you're being slowed down by any scripts running behind the page you're trying to display.
