Why not just a StringMorph with correct background?
That doesn't look possible with the current implementation. It just draws
the string with no background:
StringMorph>>#drawOn: aCanvas
...
"super drawOn: aCanvas. <- This line doesn't exist"
aCanvas drawString: contents in: bnd font: self fontToUse color: color.
>From the "... color: color" above, it looks like StringMorph is hijacking
the instVar it inherited from Morph, which usually means background color,
to use for the text color.
If you hack drawOn: to
...
self color: Color white.
super drawOn: aCanvas.
aCanvas drawString: contents in: bnd font: self fontToUse color: Color
black.
you get the halo label you're looking for but of course break everything
else.
So I think that if we want StringMorphs to have backgrounds, we have to add
a textColor instVar, initialize color to Color transparent, and rewrite all
color assignments in StringMorph to set textColor.
In short: not for 3.0.
