When I use v.digit to delete internal boundary lines in patched vector
files, I have a problem in the Window menu. It  will not display unlabeled
lines with the "U" command. It shows the set of labeled lines correctly but
when I try to show unlabeled lines (which should be the inverse set) it
shows nothing. I tried changing the background color but it did not help.
Any ideas?

Thanks.

What version of GRASS are you running? How did you get it?
What operating system is grass running on?
Did you try grass5.0.0pre5 to see if it hat the same problem yet?

I am running grass 5.0.0pre3 built from source on Solaris 8 Sparc 32. I
have not tried pre5.

This is a matter of expectation vs. function. The v.digit->Windows menu->Show
Unlabeled Lines function only displays vectors that meet the following 
criteria:

map->Line[line].att == 0 (i.e. no label)
map->Line[line].type == 1 (i.e. type "LINE" 
from /src/include/vect/dig_defines.h)

I expected to see unlabeled area edged (map->Line[line].type == 2) as well.
Possible solution are:
1) Add "||(type == AREA)" at line 100 of display_line.c to include unlabeled
area lines in the existing function.

2) Add a menu item to "Display unlabeled area edges" to Window or Toolbox 
menu by adding a "Display_uarealines" to globals.h and copying and modifying
the code for unlabeled lines in display_line.c, replot.c, states.c, window.c.
and menu.i (and others ?).

There is a hidden Window menu item for:
 { "u - Unlabeled Areas",              'u', -1 }
This is the same function as the Display Unlabeled Areas item under the 
Toolbox menu. It shows lines associated with areas where Area[i]->att == 0.
Another hidden menu item on the Customize->Colors menu is 
{ "U - Update the monitor",         'U', -1 }
This redisplays the monitor with the new settings without leaving the Colors
menu - very handy for checking the results of changes. It seems to work 
perfectly fine, I think it should be added to the visible menu.

interesting bug, pity this was never fixed.


GRASS 5's v.digit is no longer being maintained, so closing bug as "won't fix".
