    Default Qfiledialog Problem - (Beginner)

    Hello guys,
    I create simple designer application.
    in which i implemeted a filedialog to retreive the file.

    I followed the documentation, and did it .
    It compiled & ran properly
    and when i click the button , it just access the floppy drive and then nothing happens

    <code>
    void VRML2MVRDlg:n_Browse_clicked()
    {
    // QString filename = QFileDialog::getOpenFileName( QString::null, "VRML Files (*.wrl)", this, "file open", "VRML File Open" );
    QFileDialog* fd = new QFileDialog(this);
    fd->setDirectory("C:\\");
    fd->setFileMode( QFileDialog::AnyFile);
    fd->setViewMode(QFileDialog:etail);
    fd->setFilter("VRML Files (*.wrl)");
    QStringList filenames = fd->selectedFiles();
    QString filename;
    if (!filenames.isEmpty())
    filename = filenames[0];
    }
    <code>

    Looking forward for your reply.

    You have to call QDialog::exec() or QWidget::show() to make the file dialog visible. Most likely you want the first one which gives you a modal dialog (blocking until the user closes it).

    Qt Code:
    1. if (filedialog->exec() == QDialog::Accepted)
    2. {
    3. // do something
    4. }
    To copy to clipboard, switch view to plain text mode

    Thanks jpn for your reply.
    Still I have a problem in displaying the file name in lineedit .
    again ..
    it compiles and nothing happens.

    I inserted two lines to do it. I dont kow whether its right or?
    m_VrmlFile is the object name of the lineedit.

    code

    QFileDialog* fd = new QFileDialog(this);
    if(fd->exec()== QDialog::Accepted)
    {
    fd->setDirectory("C:\\");
    fd->setFileMode( QFileDialog::ExistingFile);
    // fd->setViewMode(QFileDialog:etail);
    fd->setFilter("VRML Files (*.wrl)");
    QStringList filenames = fd->selectedFiles();
    QString filename;
    if (!filenames.isEmpty())
    filename = filenames[0];

    m_VrmlFile = new QLineEdit;
    m_VrmlFile->setText(filename);
    }

    looking forward to your reply
