Qt List File And Directory

In this tutorial, I will create a tutorial how Qt List File And Directory at a location. From this method, we can know list all files and directory, only directory or only files at location we defined.  In this Qt List File And Directory tutorial, I create a simple form with radio button to select method we want. You can choose to search files and directory, only directory or only files at a location.  I use some function in QFile, QDir and QFileInfo to searching this file or directory. This is a algoritm how we can get Filename and Directory at a location with this Qt List File And Directory tutorial :

//list file and directory function
bool Qt_List_File::listFileAndDirectory( QDir dir)
{
	bool ok = dir.exists();  //check if directory exist
	if ( ok )
	{
		//set fileinfo filter
		QFileInfoList entries = dir.entryInfoList( QDir::NoDotAndDotDot |
				QDir::Dirs | QDir::Files );
                //loop over entries filter selected
		foreach ( QFileInfo entryInfo, entries ) 
		{
			QString path = entryInfo.absoluteFilePath();

			if ( entryInfo.isDir() )	//check if entryInfo is dir
			{
				if ( ! listFileAndDirectory( QDir( path ) ) )
				{
					ui.plainTextReport->appendPlainText(path);
					ok = false;
					break;
				}
				ui.plainTextReport->appendPlainText(path);
			}
			else
			{
				ui.plainTextReport->appendPlainText(path);
			}
		}
	}

	if (ok && !dir.exists(dir.absolutePath()))
		ok = false;

	return ok;
}
