Salvatore,

I cannot reproduce this problem with current implementation from svn. Please
update source code, recompile, install, and test again.

Andi,

to be sure, are you able to reproduce this problem ?

my source revision is 913004

It seems to me that is a Qt problem. I feel that digikam keeps the mouse
pointer still over the photo thumbnail when it leaves the photo area for the
scrollbar area. But as i am really far from being a dev i bet i'm saying
no-sense things.

btw is my source up to date enough?

Wow, just installed QtMod from today's build (20090118, Archlinux), and somehow
compilation is like 2 times faster now.
They seem to have changed some things, because I also needed to clean my
digiKam build dir, since moc files are not compatible anymore.

I will report if the bug is present in this fresh qt installation.

Bug is still present, also note that this will happen in normal view mode, too.
You don't have to be in fullscreen mode to see this issue.

this is true, but is really easy to avoid it and more difficult to reproduce.
In fullscreen mode it seems you can't avoid it!

No, worse :-)
If you leave the rating widget, digiKam crashes.

Andi,

Testing indeep, i cannot reproduce the crash here.

There is no reason for that :

bool ImagePreviewBar::eventFilter(QObject *obj, QEvent *ev)
{
    if ( obj == qobject_cast<QObject*>(d->ratingBox) )
    {
        if ( ev->type() == QEvent::Leave)
        {
            if (d->ratingItem)
            {
                unsetCursor();
                d->ratingBox->hide();
                ThumbBarItem *item = d->ratingItem;
                d->ratingItem      = 0;
                item->repaint();
            }
        }
    }
...

item->repaint() is called only if d->ratingItem exist.

No crashes for me, and problem no more reproducable.

(btw: you dont need any cast at all at the place of the qobject_cast I think)
