Fonts with non-standard sizes?

Hi,

I've made a morph which contains some text, and the font size should
depend on the size of the morph.

However, if I just try to set the font using
StrikeFont class>>familyName:pointSize: or TTCFont class>>family:size:, it only
gives me fonts in certain predefined sizes.

I know I can choose my own size using StrikeFont class>>fromUser, but
what's the best way to do this in my code, non-interactively?

Oh, and should I prefer TTCFont or StrikeFont, or does it not matter?

And what should I use for the font family, for maximum portability?
Can I assume BitstreamVeraSans is always available?  What's better
than assuming that?

cheers,
Simon

  Simon,

  What version of Squeak are you using?

  This is a good starting point. StrikeFont class>fromUser calls:
StrikeFont class>fromUser:allowKeyboard:, and down in the method, you
find lines like:

  ptMenu add: 'new size'
      target ... #addNewFontSizeDialog: ...

This suggests that for the 'new size' menu item, a message whose
selector is addNewFontSizeDialog: is sent to an object.  And if you
look at the implementors of the method, it is TextStyle.

  So, if you evaluate:

  (TextStyle named: 'BitstreamVeraSans') addNewFontSize: 120.

you can add the new size.

  StrikeFont is pixel font and not good for making new size
programatically.  Your safe bet is on TTCFont.

  Nobody would lobby to remove it but you could do:

        TTFontDescription default name

to figure out the "default TrueType font" in the current system.

Yoshiki,

I'm dithering around between different versions for different uses, 3.10
and OLPC developer image, hoping that at the level I am working, my
code will work on both.

Thanks for your reply, it was really useful.

cheers,
Simon
