Using San Francisco Font Weights

[Scott_Crick]

Maybe this is incredibly easy and I’m just completely missing it, but does anyone have any tips on how to use the various weights of the San Francisco font? I have a need to use San Francisco Display Black in an UI element and I cannot for the life of me figure out how to get it.

I’d appreciate any pointers!

Maybe like this:
control.FontName = "SFProDisplay-Black"

Thanks for the suggestion! Unfortunately, that’s not it. It just gives me standard San Francisco.

I have a method as part of the Ohanaware App Kit which takes the font weight and returns a font name that works with Xojo.

Thanks Sam! I looked in the latest App Kit release and think I found to what you were referring. Unfortunately, I still don’t know how to refer to San Francisco specifically. However, I’m now thinking maybe that was the wrong approach. One thing I did find in App Kit was a reference to .AppleSystemUIFontHeavy. When I use that as the font name, I get exactly what I was looking for. It seems to work fine, at least in initial tests.

Thanks for pointing me in the right direction!

I am sorry for not being clear Scott, I am gald that my rather vague directions got you there.

This is what I use to get a heavier font weight in the UI.
me.textFont = NSFontSystemFontName( NSFontWeightMedium, 13, false )

It is weird, but I think it’s done that way so you’ll get whatever the system font is.

[Scott_Crick]

That methodology does make complete sense. Apple’s changed system fonts a number of times over the years. Hard-coding the font doesn’t make sense. Obviously, why Xojo provides “System” as a font. Just doesn’t have the various weights. Your method does.

For completeness: If people are displaying HTML content and want to use the same system font. The following CSS will help.

font-family: -apple-system;
