documentation

this used to be a very simple demo application,
but migrated into a quite nice tool, includes all kinds of
warning and information boxes, background processes for directory-
reading and internationalized strings. A good example for beginners,
on how to do things .... (and maybe how not to do things ;-, since some
stuff is historic and was implemented at times when better mechanisms
were not available)
See additional information in 'doc/misc/fbrowser.doc'.
WARNING: files edited with FileBrowser will have leading spaces (multiple-8)
being replaced by tabs. If tabs are to be preserved at other
positions (for example, sendmail-config files) they will be
corrupt after being written.
[instance variables]:
checkDelta <Integer> number of seconds of check interval
(looks ever so often if shown directory
has changed). You may make this number
higher, if your network-times are
incorrect and thus, the filebrowser
checks too often.
compressTabs <Boolean> if true, leading spaces will be
replaced by tabs when saving text
some of the defaults (long/short list etc.) can be set by the resource file;
see FileBrowser>>initialize for more details..

"the code below may look somewhat complex -
it reads the directory first for the names,
then (in followup sweeps over the files) gets the
files type, info and icon in a forked subprocess.
This makes the Filebrowsers list update faster, since the fileInfo
(i.e. stat-calls) may take long - especially on NFS-mounted directories.
The file reading is done at lower priority, to let user continue
his work in other views. However, to be fair to other fileBrowser,
which may also read directories at low prio, give up the processor
after every entry. This shares the cpu among all fileBrowsers;
Therefore, browsers which read short directories will finish first.
ST/X users love this behavior ;-)
