问题
I'm using qt designer only for ui layout
This is almost the same question as this one : QVBoxLayout: How to vertically align widgets to the top instead of the center
but i'm interested on how to do that in qt designer. I don't see any option in QVBoxLayout for that top alignment.
回答1:
Right-click the relevant widget and select Layout alignment > Top.
(NB: the new alignment will only be shown in preview mode).
