推荐答案

我不能说在使用<$ c时，我的用户界面的其他部分$ c> 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 ）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.
