How might one achieve a fixed width column containing fixed width widgets within a resizable row using Spec Layouts?
<--- Resizable Space --->| Fixed Width |<---Resizable Space --->
Where the Fixed Width space might have something like a left justified input field and a right justified button or something. The best I can achieve is everything resizable, which Spec excels at! I have tried adding three columns to the row with the center column a fixed width (newColumn:width:), but I can't seem to get it centered.
I have even tried adding dummy widgets as in the code below, which creates a resizable column taking up the first half of the space, followed by a fixed width (100) input field, followed by another resizable space (sharing the right half of the column with the fixed width column):
^ SpecColumnLayout composed
newRow: [:row |
newColumn: [ :col | col add: #spacer1 height: 30 ];
