Hi,
I am trying to write a small cross platform application which shows an
icon view display of images. These images are loaded in a thread since
they are quite large. The loading thread simply sends a thumbnailed
QImage in a signal which is observed by my Model.

My subclass of QAbstractItemModel::data() returns QIcon( thumbnail )
for the DecorationRole to display the image on the View.

This works perfectly fine on Linux, but Windows shows no decoration,
simply the associated text returned by DisplayRole.

I suppose the real problem is that I don't have a windows build
environment, but I'm passing off the code to someone else to build.

Using Qt 4.3
