Call it after you modified the widgets in the group, if at all.
You _may_ see differences, if you define a resizable() widget within a
group and then resize the window/group. I'm not sure what it does
_exactly_, but if you see weird widget positions after resizing, then
you may have to call it after assigning/modifying widget positions
within the group.
