different scale of Designer and App - how to fix it?

  • Hello!
    Want to run a downloaded Qt-project on Windows 10.
    I'm able to modify the UI, but if I start the app
    all widgest are too small and narrowly,
    only the text-fonts are as defined in designer.

    Have you a fast advice for newbie**?**

    Thank you

    here the comparison:
    scale differs

    Open the form with Qt creator and set a layout to that mess. Right click on the bottommost widget (the background) right click and select Set layout > Grid layout from the context menu.

    Kind regards.

  • Thank you for your fast answer

    I could do as you suggested.

    Now there is a other quirk;

    a QToolBox with 4 QWidget's vertical aligned.

    In started up only the half is visible, movable with sliders.

    If I enlarge the toolbox all is enlarged.

    Where to do enlarge, that all is visible without sliders?

    Thank you

    You lost me. Could you attach another screenshot of what the other "quirk" is?

  • here the running App
    There is a drawing area and a toolbox area, which I want to enlarge

    1. QBoxLayout::setStretch(int index, int stretch) and use i.e. vertical layout. In this case it should be (most probably) QBoxLayout::setStretch( 0, 0) this will expand first widget based on it's content layouts setup.
    2. set fixed size for QToolBox
    3. use Splitters with will allow to manually resize areas. I think this is most appropriate solution for this case.

  • @LuGRU Thank you,
    after some online tutorials I was able to fix it.
