How to set QPlainTextEdit 's text to mapper->currentIndex?

[Panoss]

I want to convert mapper->currentIndex() to string, in order to put it in a QPlainTextEdit.
I tried:

int i = mapper->currentIndex();
ui.currentIndex_txt->setPlainText(i.toString());

Also:

QString *i = QString(mapper->currentIndex());

But both fail.
How should I do it?
