QStyledItemDelegate, QStyle::State_MouseOver MAC issues

[migel]

The mouse over does not work on mac. Am I doing it wrong ?

QStyleOptionViewItemV4 optionV4 = option;
    initStyleOption(&optionV4, index);
 
    QStyle *style = optionV4.widget? optionV4.widget->style() : QApplication::style();
 
 
    QTextDocument doc;
 
 
    if (optionV4.state & QStyle::State_MouseOver) {
        doc.setDefaultStyleSheet("a {text-decoration: underline; cursor:pointer}");
    } else {
        doc.setDefaultStyleSheet("a {text-decoration: none;}");
    }
 
    doc.setHtml(optionV4.text);

QStyleOptionViewItemV4 optionV4 = option;
    initStyleOption(&optionV4, index);

    QStyle *style = optionV4.widget? optionV4.widget->style() : QApplication::style();


    QTextDocument doc;


    if (optionV4.state & QStyle::State_MouseOver) {
        doc.setDefaultStyleSheet("a {text-decoration: underline; cursor:pointer}");
    } else {
        doc.setDefaultStyleSheet("a {text-decoration: none;}");
    }

    doc.setHtml(optionV4.text);

To copy to clipboard, switch view to plain text mode 

Also looks like the "cursorointer" does not work on all platforms, any ideas ?

Really no solutions ??

this is my full func. When I mouse over nothing happen, but when I use the scroll on my mouse then is highlighted.
Also can't get the cursor changing working on all platforms. any ideas ??

Try setting something like this first:

widget->setAttribute(Qt::WA_Hover, true);

Then see if QStyle::State_MouseOver works on Mac.
