How can I change QT listview background from delegate? -

-

i have listview in form , have item delegate it. need changing item's background color in terms of something, item delegate.

ok let's have listview , filled list

"blue", "red", "green"

on other hand have item delegate listview. need change items' background colors own colors.

you have overwrite paint(self, painter, option, index) function in delegate in order change way items painted.

for instance:

class mydelegate(qitemdelegate):      #...      def paint(self, painter, option, index):          painter.save()                   # can restore original painter later.         painter.setbrush(qbrush(qt.red)) # set background color.         painter.restore()                # restore original painter.

what now?

now know how paint background need value of item being painted can decide color be. can use last argument of paint function, index, qmodelindex instance can use getting value you're looking for.

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
