Select folder and upload all files from folder to server

[koahnig]

@developerNancy

Did you include QDirIterator header?

[developerNancy]

@koahnig Yes

[koahnig]

@developerNancy

You need to post a larger section of the code where the problem is.
Also a larger stretch of the error messages are helpful.

What is the OS and compiler you are using?

[developerNancy]

@koahnig I am using ubuntu I have already posted the code to upload file on server and for select the single file my code is void

  void MainWindow::selectFileDownload()
 {

     QString downloadlocation = QFileDialog::getOpenFileName();
    QDir dir = QFileInfo(downloadlocation).absoluteDir();
    qDebug() << dir;
    qDebug() << downloadlocation;
     this->downloadLine->setText(downloadlocation);

}

@developerNancy There is no such constructor. Please check the documentation: http://doc.qt.io/qt-5.8/qdiriterator.html

[developerNancy]

@jsulm I have not Implemented directory yet it is a selected file method.

[developerNancy]

@developerNancy
Using this code
QDirIterator UploadFolderFiles(UploadFolder, QDirIterator::Subdirectories );
while (UploadFolderFiles.hasNext()) {
qDebug() << UploadFolderFiles.next();
}

My output is this:
/Desktop/testingQT"
/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

But I want only files.

@developerNancy

well u left out the list of files u want
so that seems to mean no files when u dont give it a list.

[developerNancy]

@mrjj My output is this:
/Desktop/testingQT"
/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

But there is . and .. also I want only files

[developerNancy]

@mrjj I want files only without . and .. means 1st is file name and second null and third also null and fourth is file name.

/Desktop/testingQT/Linuxapp"
/Desktop/testingQT/.."
/Desktop/testingQT/."
/Desktop/testingQT/dfgdggd"

@developerNancy
You may have a look at http://doc.qt.io/qt-5/qdiriterator.html#QDirIterator-2 and http://doc.qt.io/qt-5/qdir.html#Filter-enum

[developerNancy]

@the_ I am new in qt I don't know how to implement too confused

[the_]

@developerNancy
Which part of the documentation don't you understand and what did you try so far?

[developerNancy]

@the_ I have almost done but I want only files......

[the_]

@developerNancy

If you only want the files within a folder just apply the correct QDir::Filters to the QDirIterator.
Just a guess: QDir::Files as can be found in http://doc.qt.io/qt-5/qdir.html#Filter-enum

--EDIT

QDir::NoDotAndDotDot is not neccessary if you use QDir::Files as . and .. are folders and not files. my bad, sorry

[developerNancy]

@developerNancy Would be great if you could provide me with some working example of this.

Thanks

[developerNancy]

@the_ said what I have to change

      QString UploadFolder = QFileDialog::getExistingDirectory(this, tr("Open Directory"),"/home",QFileDialog::ShowDirsOnly| QFileDialog::DontResolveSymlinks);

  QDirIterator UploadFolderFiles(UploadFolder, QDirIterator::Subdirectories);
      while (UploadFolderFiles.hasNext()) {
          qDebug() << UploadFolderFiles.next();
      }
 this->uploadLine->setText(UploadFolder);

[the_]

@developerNancy

Just use QDirIterator::QDirIterator(const QString &path, QDir::Filters filters, IteratorFlags flags = NoIteratorFlags) instead of QDirIterator::QDirIterator(const QDir &dir, IteratorFlags flags = NoIteratorFlags) as your constructor and apply the filters you need as listed in QDir::Filters

[developerNancy]

@the_ Thanks....

[mrjj]

@developerNancy

So in short, it is like first shown

QDirIterator it(dir, QStringList() << "*.*", QDir::Files, QDirIterator::Subdirectories);

The

QStringList() << "*.*"

tell what files you are after.

If you dont tell it, it seems to think u say "i dont want any files" which makes sense.
