QDir, list all directories?

How can I list/take only directories from a directory?
E.g.

Code:

---

QDir directory = new QDir;
directory.setFolderMode(); //example ! :P
directory.setCurrent("/home/alex/");
for (int i =0; i > directory.count(); i++){
directory.at(i) //mpla mpla...
}

---

Very sample code, it's just to understand what i want to achieve...
Well, that's what i want to do... Take the subfolder names from a specific dir and perform some actions with each one separately...
Is there any way to do this?

Look at the filters argument to the QDir constructor or QDir::setFilter()

the setfilter takes qstring as argument....Cannot filer the dirs...!

QDir::setFilter() does not take a QString argument, something you would have noticed if you bothered the read the documentation before declaring that it "Cannot filter the dirs...!". Similarly, the filters argument to the constructor does not take a QString argument.

is setFilter(QDir :: Dirs) what you want?

For a reason, I get error out of index or something like this with this solution........ :/

As you said yourself, it's for a reason.

And the code is ... :p

Code:

---

QStringList all_dirs;
    all_dirs << parent_folder;
    QDirIterator directories(parent_folder, QDir::Dirs | QDir::NoSymLinks | QDir::NoDotAndDotDot, QDirIterator::Subdirectories);
 
    while(directories.hasNext()){
        directories.next();
        all_dirs << directories.filePath();
    }

Where parent_folder is the folder whose you want all of his subdirectories.

QDir::at() and QDir::setFolderMode() are not real , are they ? because they're not on Qt 5 at least.

Look at QDir::entryList() or QDir::entryInfoList() depending on whether you just need the directory names or more info like modification dates, etc.
