Hi,

You'll have to iterate through it one child item at a time and build the text yourself.

my friend help me to archive this.here is the code.
it takes a while to make the text .

void getDirText(const QString &path)
{
    // Check whether hidden file or folder collected or not
    bool isHidden = 0;

    // Store the directories
    QStringList dirs;
    // Store the files
    QStringList files;

    // Set the filltering modes
    QDir::Filters filters = QDir::AllEntries | QDir::System | QDir::NoDotAndDotDot | QDir::NoSymLinks;

    // Get hidden file or folder if true
    if (isHidden)
        filters |= QDir::Hidden;


    QDirIterator it(path, filters);

    while (it.hasNext()) {
        it.next();

        if(it.fileInfo().isDir()) {
            // Skip the given path
            if (it.fileInfo().completeBaseName() == QFileInfo(path).completeBaseName())
                continue;

            dirs.append(it.fileInfo().fileName());
        } else {
            files.append(it.fileInfo().fileName());
        }
    }

    // Make a natural sort for both file and dir lists
    QCollator col;
    col.setNumericMode(true);

    // Sort for directories
    std::sort(dirs.begin(), dirs.end(), col);

    // Sort for files
    std::sort(files.begin(), files.end(), col);

    // Store the sorted data to a string for saving it to file
    QString output;

    foreach (QString s, dirs) {
        output.append(s + "\n");
    }

    foreach (QString s, files) {
        output.append(s + "\n");
    }

    // Save path for the collected file folder list
    QString filePath = path + "/" + QFileInfo(path).baseName() + ".txt";

    QFile file(filePath);
    file.open(QIODevice::ReadWrite | QIODevice::Text | QIODevice::Truncate);
    QTextStream text(&file);
    text << output;
    file.close();
}

thanks

QString treeToText(const QAbstractItemModel* model, const QModelIndex& parent=QModelIndex(), const QString& head = QString()){
QString result;
for(int i=0, maxRow = model->rowCount(parent);i<maxRow;++i){
const QModelIndex currIdx = model->index(i,0,parent);
result += head + currIdx.data().toString() + '\n';
if(model->hasChildren(currIdx))
result += treeToText(model,currIdx,head + "    |");
}
result.chop(1);
return result;
}

then you can just QTextStream(textFile) << treeToText(myModel);

@VRonin said in qtreeview structure in a tex file:

treeToText

i am getting this error

and did not understand how to use it

jsulm

@saber Well, the error message says what is wrong. Convert QVariant to string.
Can you please stop posting screen-shots? It makes hard to copy your code and make changes...

result = head + currIdx.data().toString() + '\n';

saber

@jsulm ok .it solved the error.
but can't understand out how to use that if only i have a folder path?

How to use what?

saber

@jsulm use the function that @VRonin gives

If you have the view you have the model

@VRonin said in qtreeview structure in a tex file:

then you can just QTextStream(textFile) << treeToText(myModel);

I used the function of @VRonin but i am not understand what kind of model i need to pass to the function. Note that i have a model with which root path is root("/"). I tried to pass that model but it hanged my whole laptop. Please tell the right procedure to select the right QAbstractItemModel...
Thanks

Would you guys please help me to find out...
please.
