It appears we are miscommunicating here heavily. When I suggested
that you could either change things via PhAB or programmatically,
this was not meant to imply a choice. If you are building a static
application that will not change, you should use PhAB because it will
likely be much easier. Changing things programmatically makes sense
if you want the user to be able to modify the look.
As far as the how to part in PhAB. If you select a bunch of widgets,
you should be able to change any common properties all at once.
Of course there have been applications I’ve built where creating and
changing widgets via PhAB was time consuming and tedious do to the
large number, and regularity of them. Think a large grid. In that
case, programmatically was the way to go.
