QSound and embedded resources

[baray98]

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

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();
}

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();
}

To copy to clipboard, switch view to plain text mode 

my qrc look like this

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

<qresource prefix="/Menu" >
        <file>tool.gif</file>
</qresource>

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

anything i missed?

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)

#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

#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

To copy to clipboard, switch view to plain text mode 

#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();
        }
    }
}

#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();
        }
    }
}

To copy to clipboard, switch view to plain text mode 

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

#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

#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?
