[Pharo-users] How to create a red box with text in a big font?

[Tim Mackinnon]

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.
