help in QDirIterator to a text file
-
@Abrar made a function that works .but problems is it takes a long time to make the text file (not enter every folder and get the name).it takes long time if the folder tree is complex.
i wonder how the tree package that @mrjj pointing is take fraction of the time to make that same text file.
here is the code.
int pat = 0; QString strDir; QString getFileFolderTree(const QString &path) { // ├ // └ // │ // ── pat++; QDir dir(path); //dir.setSorting(QDir::DirsFirst); //dir.setNameFilters(QStringList("*")); dir.setFilter(QDir::AllDirs | QDir::NoDotAndDotDot | QDir::NoSymLinks); QStringList dList = dir.entryList(); for (int i = 0; i < dList.count(); ++i) { QString newPath = QString("%1/%2").arg(dir.absolutePath()).arg(dList.at(i)); QString strPat = "├── "; for (int i = 1; i < pat; i++) { strPat.insert(0, "│ "); } if (i == dList.count() - 1) { int pos = strPat.count() - 4; strPat = strPat.replace(pos, 1, "└"); } strDir.append(strPat + QDir(dList.at(i)).dirName() + "\n"); getFileFolderTree(newPath); } pat--; dir.setFilter(QDir::Files | QDir::NoDotAndDotDot | QDir::NoSymLinks); QStringList fList = dir.entryList(); for (int i = 0; i < fList.count(); i++) { QString strPat = "├── "; for (int j = 1; j < pat + 1; j++) { strPat.insert(0, "│ "); } if (i == fList.count() - 1) { strPat = strPat.replace(strPat.count() - 4, 1, "└"); } strDir.append(strPat + fList[i] + "\n"); } // QDirIterator it(path, QDir::AllEntries | QDir::NoDotAndDotDot | QDir::NoSymLinks | QDir::System); // while (it.hasNext()) { // it.next(); // if (it.fileInfo().isDir()) { // qDebug() << it.fileInfo().path(); // getFileFolderTree(it.filePath()); // } // qDebug() << "\t" << it.filePath(); // } //qDebug() << strDir; if (!strDir.count()) strDir.append(".\n"); QFile file("/home/abrar/Desktop/UI.txt"); file.open(QIODevice::Text | QIODevice::ReadWrite | QIODevice::Truncate); QTextStream out(&file); out << strDir; file.close(); return QString(); }so i need some help to dicress the time to make the text file .
help! help! help!
thanks.@saber
It shouldn't take long. But you don't say how many files/directories there are --- if it's thousands, it will take longer....You should put debug statements in or run under debugger to discover just which part is taking the time if you expect anybody to be able to help you. Saying "help! help! help!" doesn't do it.
