Re: New text system implementation

[Fred Kiefer]

Hi Alexander,

I am quite impressed by your scrren shots from the new typesetting 
environment. This is a lot more than our current system support (and 
even this is capable of more than most GNUstepers will know).

This surely is the way to go! But your description leaves a few 
questions open:

Is the new implementation finally also taking over the string drawing 
code? All the text displayed on the screen should be done by a layout 
manager. Currently we have just the other way round, the layout manager 
uses the string drawing code.

Would this new type setting also work as a background process?

You also mention that there are more methods needed for the interaction 
between text views and the layout manager, but you don't list them. What 
is missing?

You also did not explain how this requires support from the backend, 
glyph generation can only be done by the backend with specific knowledge 
on the fonts. For which backends did you implement this?

I also don't understand the proposed class hierarchie for layout 
managers. Why should NSLayoutManager be the sub class that is restricted 
to horizontal layout. I rather would expect this to be the more general 
super class, whereas there is a GSHorizontalLayoutManager that does the 
more specific things.

Could you also provide some details about the difference from your 
typesetter classes to the Apple ones?


I am looking forward to the time, where I can use this code myself!

Keep this good work up
Fred
