how to use void QDir::setPath(const QString &path) to assign a relative path?

hi

i got puzzle about this piece of code :```

    QWidget(parent),
    ui(new Ui::Widget),
    musicDir(new QDir),
    musicFileInfo(new QList<QFileInfo>),
    mediaPlayer(new QMediaPlayer),
    mediaPlaylist(new QMediaPlaylist),
    imageDir(new QDir),
    imageFileInfo(new QList<QFileInfo>),
    imageTimer(new QTimer),
    imageRefreshTimer(new QTimer)
{
    ui->setupUi(this);
    ui->image->setAlignment(Qt::AlignCenter);

//    musicDir->setPath("F:/project/WriteToMyDear-master/WriteToMyDear/music1");
    musicDir->setPath("WriteToMyDear/music1");
    music_path_exist = musicDir->exists();

i got "music_path_exist" false when i use relative path "musicDir->setPath("WriteToMyDear/music1");" and absolute path works fine.

can someone give some suggesstions?

thanks

From the documentation ( http://doc.qt.io/qt-5/qdir.html#setPath ):

Relative file names begin with a directory name or a file name and specify a path relative to the current directory.

And your current directory can be anything depending on where you start your application or if you switched it somewhere in your app.

Hi
Try
qDebug() << QDir::currentPath()
and see where current dir is.
On many platform it will be in the build folder where .exe is :)
And not the project folder.
