[Qt-interest] Using stylesheet properties for QTreeView items

[Ruben Vandamme]

Hi all

I'm currently making an application themeable using Qt stylesheets. I'm
using Q_PROPERTIES to add extra parameters/options. For "normal" widgets
it's simple and documented (see 
doc.trolltech.com/4.5/stylesheet-syntax.html).

However, for Model based views (like the QTreeView) it's not so obvious
on how to do it (for the items). I'd like to do the following things in
the stylesheets:

QTreeView::item[negativeValue="true"] {
  background: red;
}

QTreeView::item {
  qproperty-foobar: 20;
}

Now, the big question is where do I need to add the needed QProperties?
After a lengthy google session, I couldn't find any example (or
documentation). Can someone say how to do it (or give an example)?
(maybe it's even not possible)


Thanks in advance
Ruben
