this used to be a very simple demo application,
|
|
|
60 |
but migrated into a quite nice tool, includes all kinds of
|
|
|
61 |
warning and information boxes, background processes for directory-
|
|
|
62 |
reading and internationalized strings. A good example for beginners,
|
|
52
|
63 |
on how to do things .... (and maybe how not to do things ;-)

WARNING: files edited with FileBrowser will have leading spaces (multiple-8)
|
|
|
68 |
being replaced by tabs. If tabs are to be preserved at other
|
|
|
69 |
positions (for example, sendmail-config files) they will be
|
|
|
70 |
corrupt after being written.

(looks ever so often if shown directory

has changed). You may make this number
|
|
|
77 |
higher, if your network-times are

78 |
incorrect and thus, the filebrowser

79 |
checks too often.
