Oops ! I promised to come  back with the OPENSTEP Font Panel behavior,
which  I promptly  tested and  documented,  but then  my notes  stayed
forgotten   unsent    between   my   NeXTstation    and   my   GNUstep
workstation. Sorry for the delay. Here it is:




There are differencies  of behavior of the Font  Panel between GNUstep
and OPENSTEP  4.2. Here is a  description of the behavior  of the Font
Panel on  OPENSTEP 4.2 on the  points where it differs.  IMHO, most of
these  differences  should  be  implemented in  GNUstep  too,  because
they're more user friendly and logical.


- When selecting a Family and Typeface (let's say Courrier-Bold), then
  selecting another Family that  has the same Typeface (eg. Helvetica)
  will select the other  Family with the same Typeface (Helvetica-Bold
  will be selected).


- When selecting a Family and Typeface (let's say Courrier-Bold), then
  selecting another Family that has  more than one typefaces, none the
  same than the currently selected (eg. Shalom), then no typeface will
  be selected in the column, but  one of the typeface is used to write
  the name in the preview box.

This  should be considered  a bug,  the behavior  of the  GNUstep Font
Panel, writting noface  is better here. But IMHO, it  would be best to
select  the first  typeface  in the  column  and use  it  in the  name
written.

- There are  some exceptions probably due to  some equivalence between
  some typefaces. With:

        Textbook-Medium
        Textbook-Italic
        Textbook-Bold
        Times-Roman
        Times-Italic
        Times-Bold
        Times-BoldItalic

when selecting Times-BoldItalic, then  clicking on Textbook selects no
typeface ;  but when selecting Times-Roman, then  clicking on Textbook
selects the  Medium typeface. Regular, Medium, Normal,  Roman seems to
be equivalent.

I think that this feature  introduce some strangeness to the algorithm
and that  we should keep clear  and logical rules and  we should avoid
it.



- When selecting a Family and Typeface (let's say Courrier-Bold), then
  selecting another Family that  only has one typeface (eg. Palladam),
  then this typeface will be selected again.


- In any cases, when selecting again a Family having a typeface of the
  same name than  the last typeface selectioned by  a click, then this
  typeface is selected anew.




- In all cases,  when selecting a new family, a new  typeface or a new
  size, the preview mode is reset.

- The preview mode can be locked  on with a shift click on the Preview
  button.

I think that  the behavior of the GNUstep Preview  button is more user
friendly here. In addition, the current computer should be fast enough
to give good response times when browsing the fonts with preview on.


- In preview mode, the preview box  is editable by the user. Once this
  box has been edited, it's not replaced by the new font name.


- In Edit.app,  for example, when  the preview mode is  not activated,
  activating a text window activates the preview mode with the current
  font   of    the   text   window.   I   guess    that   means   that
  setPanelFont:isMultiple:  when  NO  is  passed  as  second  argument
  activates the preview mode.



A feature  that would be very  useful (when there are  more than three
fonts installed):

- after  a click  in the  Family column,  the up  and down  arrow keys
  should select the previous or the next family.

- after a  click in the  Typeface column, the  up and down  arrow keys
  should select the previous or the next typeface.

- after a click in the Size  column, the up and down arrow keys should
  select the previous or the next size (listed in the column).

It should  be logical to  add processing of  the left and  right arrow
keys to navigate between the columns too.
