Re: Small FontPanel glitch.

[Fred Kiefer]

Hi Pascal,

I tried to implement some of the font panel features you did describe.
Please test them if they fit your expectations. As for the keyboard
navigation and the text editing we need a lot more support from the rest
of the gui lib. NSBrowser still lacks the up and down navigation and
currently it is not even possible to change the size value with keyboard
input. As soon as this is there I will add more of the listed features.

Cheers
Fred
