8 Special Applications                                        TeraDesk

Tera Desktop can mark  some installed applications  for  special uses,
such as e.g. an editor or a file viewer. These assignments can be made
in the Set applications... dialog.

Currently,  one of the following  special roles can be assigned  to an
installed application:

  . Editor                 (only one application can be marked)
  . Viewer                 (only one application can be marked)
  . Autostart              (more than one application can be marked)
  . Shutdown               (more than one application can be marked)
  . Resolution changer     (only one application can be marked)
  . File search            (only one application can be marked)
  . File comparing         (only one application can be marked)
  . Floppy format          (only one application can be marked)
  . Right button extension (only one application can be marked)

Applications specified for  viewer, shutdown, resolution changer, file
search,  file comparing  and  floppy formatting  will,  if  specified,
completely substitute TeraDesk's internal routines  for handling those
operations.

Application flagged  as  'Right button extension'  will  be  activated
whenever  the right  mouse button  is clicked.  If the  application is
already running, VA_START  will be sent to it. If  there are  selected
objects in  a directory window or on the desktop,  their names will be
sent to the  application. The user should note that, if an application
is flagged as 'Right bbutton extension',  normal TeraDesk's  behaviour
regarding the  right mouse button  clicks  (single  right-click is  by
default treated as right-button-pressed-plus-left-doubleclick) will be
disabled.

Applications flagged as 'Autostart' will be started automatically when
TeraDesk starts. There will be a delay of a couple of seconds  between
each application  being  started,  to  allow  the  started application
to configure itself, shrink used memory, etc.

Applications  flagged as 'Shutdown'  will execute  with  a delay  of 6
seconds between them,  when 'Shutdown' is selected among Quit/Shutdown
options in  the dialog activated from the File menu.  This  (or these)
application(s),  if specified,  have  to perform all activities needed
for shutdown;  the internal  shutdown  procedure  of TeraDesk  will be
disabled.

Some special application uses become effective immediately after being
set; some become effective upon  next start of TeraDesk (assuming that
the desktop configuration has been saved meanwhile).

It may be of interest  to note that,  if a special application  marked
for autostart,  shutdown,  floppy formatting or  video mode changer is
already running,  any request to start it again  as a 'special' one is
silently ignored  (e.g.  if an  autostart-marked application  is still
running when  TeraDesk is restarted,  the said application will not be
started again).
