问题 I have a QLabel with a Qt stylesheet that sets a dark background: QLabel { background: black; color: white; } This works fine until I add text with an embedded URL and set the Qt::TextFormat to Qt::RichText . The link displays as the default dark blue, which is hard to read on a dark background. I've tried customising it via a stylesheet such as: a { color: white; } QLabel!visited { color: white; } but this doesn't have any effect. The one thing that does seem to work is changing the

问题 I have several stylesheets. The first one is a stylesheet with some styles that I would like to use as defaults. Depending on several factors, the code being used to generate the page may include some stylesheets with values that should override the defaults.

问题 Does anyone know how to add stylesheets in a template with Symfony 1.4 ? I have tried everything I can think of, from modifying frontend/config/view.yml to modifying the template itself - bothing works. I have seen from my searches, that other people have had the same problem. There seems to be a clash of sorts between using include_stylesheets and use_stylesheets - however this is not documented anywhere AFAIK. 回答1: Edit: Ok I think I got it now. You should add include_stylesheets() into the
