Ack! My bad advice. The default behavior for the layout is to partition the available space to all columns except that it will honor the managed widget's sizePolicy value. The default value for sizePolicy is 'preferred' -- change the horizontal policy of the managed widgets to 'ignored' so that the layout widget will always partition the widgets to the desired value.

However, I suspect you want the layout to demand N * maxWidth space for N managed widgets where maxWidth is the largest preferred width found among the N widgets. I suspect you will have to derive from, say QHBoxLayout, and implement your own minimumSize() (and perhaps invalidate() too) which will visit all children, ask each for their minimumSize() value, and return the largest value found * N plus some margin and spacing values.

Sorry for the misdirection.
