Using Roassal, I would do:
-=-=-=-=-=-=-=-=-=
v := RTView new.
s := RTMultiCompositeShape new.
s add: (RTBox new color: Color red; size: 500).
s add: (RTLabel new height: 70).
v add: (s elementOn: 'Hello World').
v open
-=-=-=-=-=-=-=-=-=


Cheers,
Alexandre

Hi guys - I�m a bit stumped on how to create things in big text with a set background colour. I thought I understood - but it just doesn�t seem to work.
I was thinking I could create a container morph, set its background colour (which works), and then put a StringMorph inside it with a set font. This last bit I can�t get to work - I can do bold, but not a bigger font size. I�ve tried different things but am missing the magic sauce - can someone spot my mistake? Below, I�ve tried using a font name that I can see in the Pharo settings dialog but it doesn�t work? I also tried using LogicalFont with no success either.

tMorph := StringMorph new.
font1 := LogicalFont familyName: 'Arial' pointSize: 24.

tMorph contents: 'Hello World';
fontName: 'Open Sans' size: 24;
emphasis: TextEmphasis bold emphasisCode.

bMorph := Morph new
color: Color red;
addMorph: tMorph.

bMorph openInWorld.
