4.7 The listbox dialog                                        TeraDesk

TeraDesk   maintains  lists  of  filetype  masks,  window icon  types,
executable   program   types,   installed  applications  and  assigned
filetypes.  The same type of dialog,  containing a  scrollable listbox
and  five  edit buttons is used to maintain all these lists, but it is
invoked through divers menu items, depending on the use:

Set mask...   to  maintain  a  list  of  predefined filetype masks for
TeraDesk's Directory windows

Set applications... to maintain a list of installed applications

Set program types... to maintain a list of executable file types

Set window icons... to  maintain lists of  icons assigned  to  certain
filenames, filetypes, or folder names

Set document types... to maintain lists of  document types assigned to
applications.  This is  a child dialog  and it is activated  from  the
Set applications... dialog.

Listbox content  is manipulated by five buttons:  Add,  Edit,  Delete,
Up-arrow and Down-arrow.

Add:  opens a child dialog  to enter  data  for an item  which will be
added to the list at the highlighted  position. Depending  on the type
of item being added,  an appropriate dialog is opened.

Edit:  opens  a child dialog  to  edit  data  for an  already existing
item.  Depending on  the type  of item  being  edited,  an appropriate
dialog is opened.

Delete: deletes the highlighted item in the list.

Up-arrow: moves an item up in the list.

Down-arrow: moves an item down the list.

The  purpose  of  the  last two  buttons is to enable editing the item
order.  TeraDesk searches all lists starting from the beginning, until
the   first   match  is  found.  It  may  be  desirable  to   put  the
oft-needed items  nearer to the top of the list,  for faster response.
Also, if more than one list item are defined for similar objects, more
specific items should be placed in a list above the more general ones.
This is the case, for example, with documenttype assignments for files
with specific names, as exceptions to generally assigned types.

Items  can  be added (or edited) in all of TeraDesk's lists, except in
the lists of  document-types  assigned  to applications, in two  ways:
either  you  can  manually enter all data related to an item,  or  you
can select  an item in a directory window or on the desktop, and  then
open  the  desired   dialog  to  modify  the  default  settings  which
TeraDesk   assigned  for  an  item  added  to  a  list  in  this  way.
Document-types  assigned to  applications can be edited only manually,
being in a child dialog (i.e. they  can not be selected in a directory
window).
