</div></div>Same here. Almost certainly, this is a Qt bug. Please file a bug report. You<br>
should be able to workaround this behavior by subclassing QListWidget() and<br>
adding custom event handler. You will want to do that anyway, since the<br>
QListWidget appearing in the top left corner isn't that useful either.<br>
