Yann,

Thanks for the patch... It's sound fine for me...

Andi, What do you think about ?

Gilles

Comment 5 Andi Clemens 2008-12-01 13:09:48 UTC
Sounds ok, although I can not reproduce the crash here... moved my whole albums and images around, works like a charm.

Comment 7 Marcel Wiesweg 2008-12-01 19:32:50 UTC
Yann, you see that I committed one line of your patch that fixes a problem that can lead to a crash.

As to the rest of your patch:
If you remove index first, then index and not index+1 already points to the next entry. If you increment index, you get the entry two slots after the initial entry. Or am I mistaken?
Comment 8 Yann LE HIR 2008-12-01 20:00:18 UTC
Yes, you're right about my patch , I completly forgot about this index changing after a remove.
But with your patch the program will never delete the first element (id 0) of a list which has 1 element.

So maybe doing something like that :

d->urlList.removeAt(index);
if (!d->imageInfoList.isEmpty())
    d->imageInfoList.removeAt(index);

if (index < d->urlList.size())
{
    // Try to get the next image in the current Album...
    d->urlCurrent       = d->urlList[index];
    d->imageInfoCurrent = d->imageInfoList[index];
    return true;
}
else if(index - 1 >= 0)
{
    // Try to get the previous image in the current Album.
    --index;
    d->urlCurrent       = d->urlList[index];
    d->imageInfoCurrent = d->imageInfoList[index];
    return true;
}
