The example below demonstrate the problem, the hover events are emitted only on the border of the item but not on the item himsef. If I don't draw a border, events are never emitted. Platform    Linux-2.6.32-33-generic-i686-with-Ubuntu-10.04-lucid Qt              4.6.2  (probably, the problem is here) Python       2.6.5 PyQt          4.7.2 Sip             4.10.1 Regards ... -- Vincent V.V.

But if I append setOpacity(0.3), hover events works correctly, strange, no ? Cheers -- Vincent V.V. Oqapy . Qarte+7 . PaQager
