Getting only the folder path to a line edit without selecting any file

[Lasith]

In my Qt c++ application I want to get a folder path into a line edit without selecting anyfile!

void MainWindow::on_button_clicked()
{

filePath=QFileDialog::getOpenFileName(this, "Get Any File");

QDir d = QFileInfo(filePath).absoluteDir();
QString absolute=d.absolutePath();
ui->lineEdit->setText(absolute);

}
currently I use the above code to achieve it! Though the folder path only appears(without the file name) in the line edit a file in the relevant folder should be selected for it! I want to get folder path without selecting any file. (folder path should appear by opening the folder only)

how can I get this done?

try
filePath=QFileDialog::getExistingDirectory(this, "Get Any File");

@Gerd Thanx bro it worked but I get folder path only upto the folder before the last folder!

just use the filePath without further modification, its already the complete path.
This code

QDir d = QFileInfo(filePath).absoluteDir();
QString absolute=d.absolutePath();

will lead you to the dir above the selected path...
