[JW Lua] Expression Categories

[Jari Williamsson]

Yes, this seems to be correct. I believe the same things apply to 
positioning, but FCTextExpressionDef::AssignToCategory() would set the 
positioning for the expression. Perhaps I should add a method that 
changes the raw text string of the FCtextExpressionDef according to the 
category as well.


Best regards,

Jari Williamsson

However, un-commenting lines (1)-(4) in the code (to change the category font programatically) the category fonts update and in the expression designer, but not the fonts in the expressions themselves. Is this right?
