How to avoid qtwebengine to crash main program?

[yetanotherqtfan]

I load many urls in a QWebEngineView object, one by one. Some urls are displayed normally, some will make my app crash. I do not know if it is a Qt problem or chromium problem. But can I avoid qtwebengine to crash main program so I can continue to load the following urls? It should be something like:

for(i=0;i<100;i++)
    {
        try
        {
            view->load(urls[i]);
        }
        catch(...)
        {
        }
    }

But since QWebEngineView::load is an asynchronous function, I could not use the above code to ignore the failed url.

If it is genuinely "crashing" I don't think you will be able to do much about it. You can use some of the QWebEngineView::load...() signals to monitor how far it is getting, but that's about it, and it won't affect the behaviour anyway. You could Google for qwebengineview crash, there are a few hits, you could see whether your situation corresponds to any of them.

@JonB Thank you for your suggestion. I would like to know if there is a method to bypass the error and continue to load subsequent urls. Is there any exception thrown by QtWebEngine that can be caught? If there is, how can I catch those exceptions?

As I said, I'm afraid not to the best of my knowledge.

You might try running your app inside debugger to get backtrace on crash. It sometimes gives a clue. I think one thing to make sure is that you have up-to-date graphics card driver. Also, you might see whether same page crashes inside Google as from QWebEngine: in principle I would expect Chromium engine to behave similarly....

QtWebEngine should not crash your app. Please file a bug report with a sample program at bugreports.qt.io.

@DJBob-Gaming Is this spam? Does not sound like any answer to the question.
