Hi,

Proceeding with this one for fun.
And i hit a little snag again. (not that i fixed the old ones..)

This is for sending a pixmap to QML.
The header side looks like this:
    Q_PROPERTY(QPixmap icon READ icon)
    const QPixmap& icon();

The source side looks like this:
    const QPixmap& ToolTip::icon()
    {
        return d->icon; // QPixmap
    }

Everything seems fine so far.
Now if i call <myclass>.icon (the Q_PROPERTY) in a console.out i see:
    QVariant(QPixmap)

I'm fine with that, however,
    QtExtraComponents.QPixmapItem
    {
        id: image
        width: 48
        height: 48
        pixmap: ToolTipData.icon
    }

doesn't do that. The QPixmapItem only takes a QPixmap, not a QVariant.
I remember patching QIconItem some time ago to accept a QVariant as
input which is then being casted to a QPixmap if possible.

So, the question here is. How do i send a QPixmap from QML to
QPixmapItem? Or would you prefer it if i patch QPixmapItem (and
QImageItem for completeness) to accept a QVariant?
I'm also wondering how this is currently working anywhere since QML
sends a QVariant(QPixmap), not a direct QPixmap. Or am i touching code
now that nobody actually uses - besides me...

Cheers,
Mark
