This a common gotcha with layout managers. A layout manager can only
manage layout vertically if the container has its vertical size
constrained, which is not the case for your dialog.
There are a number of ways to deal with this.
The following is the straight forward solution, in which you do not
let the layout manager manage the height, by using
container->setLayout(..., AlignTop | ...). This makes it look ugly
though. If you want the grid layout to equalize the height of every
row, then you need to let the layout manager manage the height (see
further).

Any alternative will require you to specify a size for either the
dialog or the dialog contents, and make sure that everything is linked
together using layout managers, thus using a layout managers on
dialog.contents().
The following is a patch which solves it in that way:
