how to set the max vertical size of a "QHBoxLayout" embedded in a QWidget set as a grid?



  • my object heirarchy looks like this:

    and the visual geometry is this:

    but i do not want the two HBox's to be evenly distributed, i want the top one to be vertically much shorter, like this screen shot showing me dragging the bottom edge up a bit:

    but when i let go it snaps back to where it was, instead of having the bottom HBox expand to fill the exposed extra space.

    i see "layoutSizeConstraint" but i can't find documentation on how to use it

    Hi,

    I haven't used designer lately but I would go with the stretch factor. Set to one for the top part and two for the bottom to get started.



  • okay apparently, WYSI-NOT-WYG

    when i RUN the app, it sizes as expected
