Reading files from a perticular folder

[suneel1310]

Hi all.

I have an application which takes a file name as the input.
Currently I am hard coding the file name in the constructor.

But, I want to read all the files from a perticular folder one by one.
How to do that ??
Using QFileDialog class i can only select a perticular file (or files) from a list of file
Thank you.

so, what is the problem? store files names in a list and then implement a loop in which you can read data from each file.

Hello my friend,

look at this little snippet from me perhaps it will help you.

QString somepath = "C:/yourpathtofolder/"
QDir somefolder = QDir(somepath);
    somefolder.setFilter(QDir::Files | QDir::Dirs | QDir::NoSymLinks);
    somefolder.setSorting(QDir::Size | QDir::Reversed);
 
 
    QStringList filenames = somefolder.entryList(QDir::NoDotAndDotDot | QDir::AllDirs, QDir::Name);
    QStringList fileListing;
 
    for (int i(0); i < filenames.count(); i++)
    {
        QString str = filenames.at(i);
		//you can also ignore the if statement for filtering your Filenames depends on your filtertext
            QDir dir(somepath+filenames.at(i));
            foreach ( QString file, dir.entryList( QDir::Files))
            {
                if(file.contains("YourFilterText", Qt::CaseInsensitive))
                    fileListing << QFileInfo( dir, file).absoluteFilePath() << "\n";
            }
    }
	//after you fill up your list and do want you want to do my friend ;o))
    foreach (QString str, fileListing)
    {
    QMessageBox::information(this, tr("My Files in Folder"),
                                 tr("File: %1 "
                                    " ")
                                 .arg(str));
    }
    fileListing.clear();

QString somepath = "C:/yourpathtofolder/"
QDir somefolder = QDir(somepath);
    somefolder.setFilter(QDir::Files | QDir::Dirs | QDir::NoSymLinks);
    somefolder.setSorting(QDir::Size | QDir::Reversed);


    QStringList filenames = somefolder.entryList(QDir::NoDotAndDotDot | QDir::AllDirs, QDir::Name);
    QStringList fileListing;

    for (int i(0); i < filenames.count(); i++)
    {
        QString str = filenames.at(i);
		//you can also ignore the if statement for filtering your Filenames depends on your filtertext
            QDir dir(somepath+filenames.at(i));
            foreach ( QString file, dir.entryList( QDir::Files))
            {
                if(file.contains("YourFilterText", Qt::CaseInsensitive))
                    fileListing << QFileInfo( dir, file).absoluteFilePath() << "\n";
            }
    }
	//after you fill up your list and do want you want to do my friend ;o))
    foreach (QString str, fileListing)
    {
    QMessageBox::information(this, tr("My Files in Folder"),
                                 tr("File: %1 "
                                    " ")
                                 .arg(str));
    }
    fileListing.clear();
