gxditview - display gtroff output files
SYNOPSIS
gxditview
[-toolkitoption\...]
[-option\...]
[filename]
DESCRIPTION
The
gxditview
program displays gtroff output on an X display.
It uses the standard X11 fonts,
so it does not require access to the server machine for font loading.
If
filename
is
R - ,
gxditview
will read the standard input.
The left mouse button brings up a menu with the following entries:
Next Page
Display the next page.
Previous Page
Display the previous page.
Select Page
Select a particular numbered page specified by a dialog box.
Print
Print the gtroff output using a command specified by a dialog box.
The default command initially displayed is controlled by the
printCommand
application resource, and by the
-printCommand
option.
Open
Open for display a new file specified by a dialog box.
The file should contain gtroff output.
If the filename starts with
|
it will be taken to be a command to read from.
Quit
Exit from
R gxditview .
The
R n ,
Space
and Return keys are bound to the
Next Page
action.
The
R p ,
BackSpace
and
Delete
keys are bound to the
Previous Page
action.
The
q
key is bound to the
Quit
action.
The
r
key is bound to the
Rerasterize
action which rereads the current file, and redisplays the current page;
if the current file is a command, the command will be reexecuted.
The
paperlength
and
paperwidth
commands in the DESC file specify the length and width in machine units
of the virtual page displayed by
R gxditview .
