How to open a directory and check this content?

I-sty

Hi,

I would like to open a directory and scanning that empty or not.

@QString directory = QFileDialog::getExistingDirectory(this, tr("Browse folder"), QDir::homePath (), QFileDialog::DontResolveSymlinks);

if (!QFileInfo(directory).size ())
{
    ui->sfTextEdit->setText ("The selected folder is empty!");
}
else
{
    ui->sfTextEdit->setText ("The selected folder is not empty!");
}@

I wrote this script, but didn't work.

QFileInfo(...).size() works only for files, try QDir(...).count().

I-sty

I dunno how to :(

I would like to select a directory and write out the content in a list.
Example:
I selected D:/Music/Adele
And the app will write that:

Adele - Someone like you -> 5mb
Adele - somename -> 6mb
.....

Look at this function:

@void QThAnalyze::SideList(QString Path) {
QVector<FileItem> *QVSideList= new QVector<FileItem>();
QDir QDPath= QDir(Path);
QDPath.setSorting(QDir::Name);
QStringList QSLFiles= QDPath.entryList(QDir::AllEntries | QDir::NoDotAndDotDot | QDir::Hidden);
if (QSLFiles.size()== 0) emit SendEmptyDirs(Side, Path);
else {
for (int count= 0; count< QSLFiles.size(); count++) {
FileItem fileitem;
fileitem.Path= Path+ QDir::separator();
if (fileitem.Path.startsWith(InitialPath)) fileitem.Path= fileitem.Path.right(fileitem.Path.length()- InitialPath.length());
fileitem.File= QSLFiles[count];
QFileInfo QFIPath(Path+ QDir::separator()+ QSLFiles[count]);
struct stat FileAttributes;
stat(QString(Path+ QDir::separator()+ QSLFiles[count]).toStdString().c_str(), &FileAttributes);
//qDebug() << QString(Path+ QDir::separator()+ QSLFiles[count]).toStdString().c_str(); <<<---------
if (QFIPath.isDir()) {
fileitem.IsDirectory= true;
Directories++;
QVSideList->append(fileitem);
if (DoStart) emit SendFiles(Side, Files, Directories, QVSideList);
QVSideList->clear();
if (DoStart && QFIPath.isDir() &! QFIPath.isSymLink()) SideList(Path+ QDir::separator()+ QSLFiles[count]);
} else {
fileitem.IsDirectory= false;
fileitem.Size= QFIPath.size();
Files++;
fileitem.LastAccess= FileAttributes.st_atime;
fileitem.LastModified= FileAttributes.st_mtime;
QVSideList->append(fileitem);
}
}
if (DoStart) emit SendFiles(Side, Files, Directories, QVSideList);
}
}@

How you can see the "QDir QDPath= QDir(Path);" contains the content of directory. "QFileInfo" and "stat" function contain the attributes.
