How can pop up be made allowed when we use javascript in Qt??

umaviswa

function saveTextAsFile()
{
var textToWrite = document.getElementById("latbox").value+"\n"+document.getElementById("lngbox").value;
var textFileAsBlob = new Blob([textToWrite], {type:'text/plain'});
//var fileNameToSaveAs = document.getElementById("inputFileNameToSaveAs").value;
var downloadLink = document.createElement("a");
//downloadLink.download = fileNameToSaveAs+".txt";
downloadLink.download = "values.txt";
downloadLink[removed] = "Download File";
if (window.webkitURL != null)
{
downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);
}
else
{
// Firefox requires the link to be added to the DOM
// before it can be clicked.
downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
downloadLink.onclick = destroyClickedElement;
downloadLink.style.display = "none";
document.body.appendChild(downloadLink);
}
downloadLink.click();
}

here i had a button in javascript which when clicked pops up a download window asking for saveas or open. it is working outside Qt. but the pop up is blocked in Qt.
i tried all the available setting changes nothing worked :(

QWebSettings *settings = ui->webView_2->settings();
settings->setAttribute(QWebSettings::JavascriptEnabled, true);
settings->setAttribute(QWebSettings::PluginsEnabled, true);
settings->setAttribute(QWebSettings::AutoLoadImages, true);
settings->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);
settings->setAttribute(QWebSettings::LocalContentCanAccessFileUrls,true);
please help . how to make it work.

Use the code-tag for your code, please. This is way too hard to read.

Why do you not use Qts integrated saveas-/open-dialog instead?

Thanks for your response Mr.thEClaw. Please let me know if there is any possible way in Qt where i can save values from html to a text file??

What exactly do you mean? Maybe have a look at "QFile":http://qt-project.org/doc/qt-5.1/qtcore/qfile.html or "QSettings":http://qt-project.org/doc/qt-5.1/qtcore/qsettings.html , depending on what you want to achieve.

here you go:
@
QWebPage* page = myWebView->page();
page->setForwardUnsupportedContent(true); //<-- IMPORTANT!
connect(page, SIGNAL(downloadRequested(const QNetworkRequest &)), this, SLOT(onDownload(const QNetworkRequest &)));
connect(page, SIGNAL(unsupportedContent(QNetworkReply*)), this, SLOT(onUnsupportedContent(QNetworkReply*)));

...

//SLOT
void onDownload(const QNetworkRequest & request)
{
//this slot is called when the user right-clicks on an element and wants to save it, i'm not sure if it may be triggered also in your case
}

//SLOT
void onUnsupportedContent(QNetworkReply* reply)
{
//this slot is called when the user should be prompted to download a file, so this is most probably the way to go for you
}
