I'm confirming this in gvim 7.2.148 on openSUSE Linux 11.1. I suspect it
is related to the bug investigated in the thread "How to redraw the
whole Vim screen after splitting new windows?".
After splitting windows, adding lines (by o followed by several times
Enter) does not cause the current line number in the non-current window
to be updated immediately. However, I have a CursorHold,CursorHoldI
autocommand which changes the color of the StatusLine and Wildmenu
groups, and when that autocommand triggers, the non-current statusine is
also updated, even though the autocommand changes neither the
'statusline' option nor StatusLineNC highlight.
Here are the relevant lines from my "almost-default" colorscheme:
----------------8<--------------------8<--------------------
" display the status line of the active window in a distinctive color:
" bold black on bright red in the GUI, white on green in the console
" (where the bg is never bright, and dark red is sometimes an ugly sort
" of reddish brown).
hi StatusLine gui=NONE,bold guibg=red guifg=black
\ cterm=NONE,bold ctermbg=darkgreen ctermfg=white
hi WildMenu gui=NONE,bold guibg=green guifg=black
\ cterm=NONE,bold ctermbg=black ctermfg=white
" make the status line bold-reverse (but B&W) for inactive windows
hi StatusLineNC gui=reverse,bold
\ cterm=NONE ctermbg=black ctermfg=lightgrey
" make the active status line colours alternate between two settings
" to give a visual notice of the CursorHold/CursorHoldI events
if ! exists("s:statuslineflag")
let s:statuslineflag = 0
endif
function! ToggleStatusLine()
if s:statuslineflag
hi StatusLine
\ cterm=NONE,bold ctermbg=darkgreen ctermfg=white
\ gui=NONE,bold guibg=red guifg=black
hi WildMenu
\ cterm=NONE,bold ctermbg=black ctermfg=white
\ gui=NONE,bold guibg=green guifg=black
else
hi StatusLine
\ cterm=NONE,bold ctermbg=black ctermfg=white
\ gui=NONE,bold guibg=green guifg=black
hi WildMenu
\ cterm=NONE,bold ctermbg=darkgreen ctermfg=white
\ gui=NONE,bold guibg=red guifg=black
endif
let s:statuslineflag = ! s:statuslineflag
endfunction
exe "augroup" s:colors_name
au! CursorHold,CursorHoldI * call ToggleStatusLine()
au! ColorScheme *
\ if g:colors_name != s:colors_name | exe "au!" s:colors_name |
endif
augroup END
----------------8<--------------------8<--------------------
Both s:colors_name and g:colors-name are set to the colorscheme name
(outside the part quoted above) when it is sourced.
Continuation lines need 'nocompatible' to be set.
Best regards,
Tony.
