Display files of a Directory

[mansu]

hi to everyone,
i'm a newbie of programming Qt (using 4.4.3 on a Unix system) .....can anyone tell me the easy way to display Files of a specific dir?
i search on the forum but i readed something about QDir and QTreeView but i don't find anything reguarding them

An example will be very appreciated.

Thanks to everyone

There's an example in QDir Class Reference:


A program that lists all the files in the current directory (excluding symbolic links), sorted by size, smallest first:

#include <QDir>
 #include <iostream>
 
 int main(int argc, char *argv[])
 {
     QCoreApplication app(argc, argv);
     QDir dir;
     dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
     dir.setSorting(QDir::Size | QDir::Reversed);
 
     QFileInfoList list = dir.entryInfoList();
     std::cout << "     Bytes Filename" << std::endl;
     for (int i = 0; i < list.size(); ++i) {
         QFileInfo fileInfo = list.at(i);
         std::cout << qPrintable(QString("%1 %2").arg(fileInfo.size(), 10)
                                                 .arg(fileInfo.fileName()));
         std::cout << std::endl;
     }
     return 0;
 }

#include <QDir>
 #include <iostream>

 int main(int argc, char *argv[])
 {
     QCoreApplication app(argc, argv);
     QDir dir;
     dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
     dir.setSorting(QDir::Size | QDir::Reversed);

     QFileInfoList list = dir.entryInfoList();
     std::cout << "     Bytes Filename" << std::endl;
     for (int i = 0; i < list.size(); ++i) {
         QFileInfo fileInfo = list.at(i);
         std::cout << qPrintable(QString("%1 %2").arg(fileInfo.size(), 10)
                                                 .arg(fileInfo.fileName()));
         std::cout << std::endl;
     }
     return 0;
 }

Look at the Directory View example. It uses QDirModel. The simplest way would be:

QTreeView * treeView = new QTreeView(this);
QDirModel * dirModel = new QDirModel(this);
treeView->setModel(dirModel);

QTreeView * treeView = new QTreeView(this);
QDirModel * dirModel = new QDirModel(this);
treeView->setModel(dirModel);
