Hi,

I'm trying to create a sort of indented list of checkboxes in the Designer. Here's how the result should look like:

I'm using Horizontal Spacers to create actual indents, setting their sizeType to Fixed and sizeHint to whatever size I like. Then I group each spacer with its checkbox and enclose them in a QHBoxLayout. Then I apply a vertical layout to the whole widget. In the Designer it looks like this:

Now, when I resize the widget, the checkboxes are no longer spaced evenly in vertical direction:

My question: how can I control the vertical sizing behavior of nested QHBoxLayouts? There appears to be no such thing as a sizePolicy for the QHBoxLayout... I've tried several options of layoutSizeConstraint, but they don't seem to have any effect.

Thanks!
