I have QListWidget, and each item has its own widget (e.g. _listWidget->setItemWidget(itm,lbl)). how can I animate expanding of QListWidgetItem when one is selected?

this, of course, doesn't work, because QListWidgetItem doesn't inherit QWidget
@QListWidgetItem * itm = new QListWidgetItem; ...
QPropertyAnimation * anim = new QPropertyAnimation(itm,"sizeHint",this);
...
anim->start();@
