    Hi and welcome to devnet,

    You should check the "bug report system":http://bugreports.qt-project.org to see whether it's something known. If not you could consider opening a new bug report providing a minimal compilable example that reproduces the problem.



  • Drag and Drop DOM elements work fine in QT5.2:
    @var a = document.getElementById("mainDiv");
    a.ondrop = function(){
    //something
    };
    a.ondragover = function(){
    //something
    };@

    File drop work fine in QT5.2:
    @a.ondrop = function(e) {
    e.stopPropagation();
    e.preventDefault();

    // fetch FileList object
    var files = e.target.files || e.dataTransfer.files;

    for (var i = 0, f; f = files[i]; i++) {
    console.log(f);
    }
    }@

    I believe it is a fault in your Javascript, try running the following URLs in your projects:

    If the problem persists then I think you have not enabled in your webView DROP, try this:
    @WEBVIEW->setAcceptDrops(true);@

    If it still does not work, you might not have Javascript enabled, try this:
    @QWebSettings *settings = QWebSettings::globalSettings();

    settings->setAttribute(QWebSettings::JavascriptEnabled, true);@

    To do all these tests, enable the "Inspector":

    @QWebSettings *settings = QWebSettings::globalSettings();

    settings->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);@

    and the right-click (before any testing) open the Console.
