[Solved] Could not make File Dialog box work. Needed help!

[inblueswithu]

Hi,

I want a File Dialog box for selecting a folder in my application.
I have used QtQuick2ApplicationViewer wizard for creating my project.
My gui is in QML & logic in C++. I tried the following ways to get File Dialog after searching in Google.

@int Library::fileDialog()
{
QFileDialog* dialog = new QFileDialog();
dialog->setFileMode(QFileDialog::Directory);
dialog->setOption(QFileDialog::ShowDirsOnly);
dialog->exec();
return 0;
}@

Second Way:

@// Testing FileDialog
QString path = QFileDialog::getOpenFileName(0 ,"Show Music Location", "", "", 0,QFileDialog::ShowDirsOnly);
mediaLocation = QDir(path);
qDebug() << path;@

In both ways, it gave same error: QWidget: Cannot create a QWidget without QApplication

Thought the issue is straight forward, I'm not aware how to create this. I'm inside a QGuiApplication!
Can some one please tell me how to achieve this.

I even tried the FileDialog component in QML. Immediately after making that visible from C++ code, it is throwing an Exception " The inferior stopped because it triggered excetption. Stopped in thread by Exception at, code: 0xc0000005; " This error is shown only in Debug mode. During runtime, it stops executing after closing the FileDialog.

I would be great full if some one help me in this.

EDIT : changed QApplication to QGuiApplication

Thanks in Advance,

Are you sure you are in a QApplication or a QGuiApplication?

sorry, its a QGuiApplication. (As is given by the QtQuick2 Application - built in types wizard). How can I solve this?

@sierdzio: It worked! <3 u man
I changed QGuiApplication to QApplication :)
I had to use QFileDialog::getExistingDirectory() for selecting a directory
Thankyou. Thanks a lot! :)
