QStringList problem :/

[hakermania]

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:

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); ?????????
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() (http://doc.trolltech.com/latest/qstringlist.html#join) and then use that string to setText in the lineEdit.

QStringList does not have the operator[]
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 [])

[hakermania]

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

[Lykurg]

How do I use it?By reading the documentation or simply try?

See - QStringList::join

[hakermania]

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:


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

See if that works.
