events - Automatically resize vim gui according to number of vertical splits -


i writing small plugin gvim automatically increases or decreases width of gui according number of vertical splits. plugin works this

if has("gui_running")   augroup resize     autocmd winenter * call <sid>resizesplits()     autocmd winleave * call <sid>resizesplits()     autocmd bufleave * call <sid>resizesplits()   augroup end endif

here resizesplits() function resizes gui window:

function! s:resizesplits()   let l:count = 0   windo   if winwidth(winnr()) < &columns |          \   let l:count += 1              |         \ endif   if l:count > 0     let l:totwidth = l:count - 1 + l:count*80   else     let l:totwidth = 80   endif   if &columns != l:totwidth     execute 'set co=' . l:totwidth   endif endfunction

the plugin works want to, not quite. seems bufleave event (and similar ones) executes before windows closed. problem instance when <c-w>o or :only. problem resizesplits function not work, since still counts old number of windows.

is there autocommand can used detect when number of windows has been changed, or bufleave-like event guaranteed executed after windows destroyed/removed?

it trivial plugin work mappings, not able work reliably ex commands :only , :close.

there's no exact event :close / :quit; closest bufwinleave, doesn't fire when buffer still visible in buffer. combine bufleave, have check buffer not visible more.

to handle unlisted buffers, can add condition checking 'buflisted' in executed autocmd.

edit after update of question

i don't think there's way intercept corner cases you've described. :only tricky. can propose work around additional autocmds on cursorhold , cursormoved. way, incorrect state persist short time.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
