QSound and embedded resources

I was trying to load a wavefile for QSound from a qrc but of no luck. I tried loading the file from my drive then QSound made its sound. I am suspecting my QSound did not find the file in qrc. Is there any trick? I did all these in the snippet below

Code:

---

int main (int argc,char *argv[])
{
 
    QApplication app(argc,argv);
 
    QPixmap pixmap(":/Menu/tool.gif"); //QPixmap foound this file in my qrc
    QSplashScreen splash(pixmap);
    splash.show();
    app.processEvents();
 
    QSound::play(":/Sounds/voices/welcome.wav"); //I did not hear any on this one
 
    MyWindow*mainWin = new MyWindow;
    mainWin->setMinimumSize(1024,740);
    mainWin->show();
    splash.finish(mainWin);
 
    return app.exec();
}

---

my qrc look like this

Code:

---

<qresource prefix="/Menu" >
        <file>tool.gif</file>
</qresource>
 
<qresource prefix="/Sounds">
    <file>voices/welcome.wav</file>
</qresource>

You missed the docs:

Note that QSound does not support resources. This might be fixed in a future Qt version.

Is there already a Qt version where QSound supports resources?

Nope.

However, you could use this trick:
1) define a class (ResourceFile) that will copy a resource to disk (in the hard-coded "resources" directory at executable file level in this example)

Code:

---

#ifndef RESOURCEFILE_H
#define RESOURCEFILE_H
#include <QFile>
#include <QString>
 
class ResourceFile : public QFile
{
public:
    ResourceFile (const QString &respath, QObject * parent = 0);
};
 
#endif // RESOURCEFILE_H

---

Code:

---

#include "resourcefile.h"
#include <QFileInfo>
#include <QDir>
 
#define FILES_DIR "resources"
 
ResourceFile::ResourceFile (const QString & respath, QObject *parent)
    : QFile (parent)
{
    QFileInfo resource (respath);
    QDir files = QDir::current();
 
    if (!files.cd(FILES_DIR))
    {
        files.mkdir(FILES_DIR);
        files.cd   (FILES_DIR);
    }
 
    setFileName (files.filePath(resource.fileName()));
    if (!exists())
    {
        QFile resfile(respath);
        if(resfile.open(QIODevice::ReadOnly))
        {
            if (open(QIODevice::ReadWrite))
            {
                write(resfile.readAll());
                close();
            }
            resfile.close();
        }
    }
}

---

2) define a class (ResourceSound) that will plug QSound to the disk copy

Code:

---

#ifndef RESOURCESOUND_H
#define RESOURCESOUND_H
#include <QSound>
#include "resourcefile.h"
class ResourceSound : private ResourceFile, public QSound
{
public:
    ResourceSound (const QString & respath, QObject * parent = 0)
    : ResourceFile (respath, parent)
    , QSound (fileName(), parent) {}
};
 
#endif // RESOURCESOUND_H

---

You can then use ResourceSound instead of QSound and get the same result (or lack of, considering the shortcomings of QSound :)).

is that official, is QSound QSoundEffect not able to work with embedded resources?
