[WASM] Get full file path name from QFileDialog::getOpenFileContent

[Mixlu]

Hi,
I would like to get the full file path name of a file with QFileDialog::getOpenFileContent but I only get the file name. Here is my code :

auto fileContentReady = [](const QString &fileName, const QByteArray &fileContent) {
        if (fileName.isEmpty()) {
            // No file was selected
            qDebug() << fileName << endl;
        } else {
            // Use fileName and fileContent
            qDebug() << fileName << endl;
       }
       QFileInfo fi(fileName);
       qDebug() << "path: " << fi.path() << endl;
        
    };
    QFileDialog::getOpenFileContent("Images (*.png *.xpm *.jpg)",  fileContentReady);

in webassembly, both fileName and fi.path() return the file name, not including the full path.
I am using Qt 5.13.2 with emscripten 1.38.30.

Short answer... you can't get the full file path of a file.

Your question is more related to safety/security standards regarding major browsers and the decisions related to them made by owner companies/foundations.

That is, javascript is not allowed to know the full path of a file shared by the user. So, fileContentReady or in general any webassembly function will end up being a javascript function, limited to the security standards imposed on js implementation by the browser.

(You can always ask the user to install a java applet :P )
