I think the issue is that if you want the TextMorph to be larger than
the text inside it (in your case none), you have to set its extent.
Here's some code that works for me. Note how I set the extent height
of "textField" based on the font size of the StringMorph. I set the
extent width to a fixed value of 100 pixels.
spaceBetweenMorphs := 10.
spaceInsideContainer := 10.
container := Morph new.
container
layoutPolicy: TableLayout new;
listDirection: #leftToRight;
hResizing: #shrinkWrap;
vResizing: #shrinkWrap;
layoutInset: spaceInsideContainer;
cellInset: spaceBetweenMorphs;
width: 200.
label := StringMorph contents: 'I''m a label.'.
font := label font.
margin := 4.
height := font lineGrid + (margin * 2).
container addMorphBack: label.
textField := TextFieldMorph new.
textField extent: 100@height. "text doesn't display if insufficient
height"
container addMorphBack: textField.
