QStringList problem :/

See how it goes, I have a pushButton and a lineEdit. When the pushbutton is clicked a FileDialog::getOpenFileNames pop-ups, then I want to put the files selected into the lineEdit:

Code:

---

path = QFileDialog::getOpenFileNames(this, tr("Files & Directories"), QDir::currentPath(), tr("All files *.*") );
    int x = path.length();
    // ui->lineEdit_6->setText(path[x] + ", " + path[x-1); [B]?????????[/B]

---

I have the number of files selected but idk exactly how to put them into the lineedit...:(

deleted QStringList has operator[]

You should use iterators to iterate the list of strings

Or add the whole list into a string (with the delimiter you want), using join() and then use that string to setText in the lineEdit.

It has: QStringList = QList<QString> => QList::operator[].

But I would prefere at() or value(). And in your case the suggested join() should be perfect.

@Lykurg: Thanks for correction, i'm used to c++ list (linked list) and keep forgetting that QList is implemented differently than QLinkedList (witch doesn't have [])

So, join() appends QStrings?
How do I use it?

By reading the documentation or simply try?

See - QStringList::join

Code:

---

QString l = "";
    path.join(l  + ", ");
    ui->lineEdit_6->setText(l);

---

doesn't workkkkkkkk
I am a beginner actually...:(:(
Can you help me on this?

I haven't tried it out, but reading the doc, I think you need to do:

Code:

---

QString l = path.join(", ");
ui->lineEdit_6->setText(l);

---

See if that works.
