[SOLVED] How to shrink QMainWindow with a QLabel including an image?

  • Hi,
    I am using several QLabels for displaying videos in my MainWindow.
    Now I have a problem with re-sizing the window.
    I can easily use my mouse to make the MainWindow bigger while the program executes.
    All the videos are automatically resized using the code below.
    But if I try to make the window smaller it is not working.
    It looks like the QLabels cannot be resized to a smaller size.

    What can I do that the user is able to make the MainWindow bigger and also smaller?

    Thank you very much :-)

    void MainWindow::updateGuiVid1(QImage img)
        if (!img.isNull())

    have you tried with
    label->setMinimumSize(1, 1)

  • Sorry for the late reply, I was away for a while.

    Actually your suggestion works perfect :-)

    Thank you very much!
