    Hello,

    I'd like to know when my WebView gets a 404 or otherwise fails to load a web page. If the URL is malformed, I can use onLoadFailed, but I don't know how to catch a 404 and respond in QML. Is this possible?

    @
    import Qt 4.7
    import QtWebKit 1.0

    WebView {
    width: 640
    height: 480
    url: "http://www.google.com/page/does/not/exist.html"

    onLoadFailed: {
        console.log("Page failed to load: " + url)
    }
    

    }
    @
    Thanks,
    Matt

      WebView is quite limited and I'm afraid you can't do that without using any tricks. Here is one of the tricks: using XMLHttpRequest to request the same url inside onLoadFailed and catch the status code, e.g, something like this:
      @
      onLoadFailed: {
      var xhr = new XMLHttpRequest();
      xhr.onreadystatechange = function() {
      if (xhr.status == 404) { print('URL not found: ' + url) }
      }
      xhr.open("HEAD", url, true);
      xhr.send(null);
      }
      @

      Cheers,
      Phi

        Hi,

        I'd recommend adding a suggestion in the bug tracker for this -- so hopefully it will become easier to handle in future versions.

        Regards,
        Michael

          I will give that XMLHttpRequest a try. Thanks for the suggestion!
