QFileDialog used as widget

? Offline

Hi!
My goal is: user can choose file (only *mp3) and after clicking twice on it it should play (so the QString to file should be send to play() funtion)
Firstly I started to work with QTreeView, but it has signal when the file is selected.

So I decided to create QFileDialog and used it as widget built-in into MainWindow.
The only problem that I have, that after double-click it dissapers. It is possible to avoid it?

Should I work with some QDialog::finished() signal or, QDialog::done()?

I would use QTreeView and QFileSystemModel.

Did you try the signal "doubleClicked":http://doc.qt.nokia.com/4.7/qabstractitemview.html#doubleClicked
