    Default open file browser and save file

    Hi all,

    I'm new to QT and I found this function in qt:

    QFileDialog::getSaveFileName

    But it is only save file name only, not data.

    May i know is there any function to let user open file browser to choose the file location and save images?

    1) get the file name to save to
    2) save the image using that file name

    Cheers,

    Maybe you could follow these steps:
    1) get the file name with path by QFileDialog::getSaveFileName. (only get the file name you wanting, no file data)
    2) use image.save method

    QString path = QFileDialog::getSaveFileName(0,
    tr("Save File"),
    ".");
    QImage image("no1.jpg");

    image.save(path);
