My QStyledItemDelegate does not behave consistently on Windows and Mac.

[ealione]

I have created a QListView that uses a QStyledItemDelegate to display some data.

In my custom delegate I have a paint event that is responsible for painting the text the way I want it

void UserListDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
...

if (option.state & (QStyle::State_MouseOver))
    {
         // Change color.

The thing is that this works fine on windows and the paint event is called each time I hover above an item. In MacOS though it does not. My widget does not care if I hover above an item or not.

This is one of the many ways that paint works differently on Mac and Windows.

Has anyone any idea on why is that?
