How to set QMdiArea::WindowOrder ?

Hello,

I'd like to set QMdiArea::WindowOrder to QMdiArea::StackingOrder , so when i close the active MdiSubWindow the one underneath get activated (this is not the default behavior)

Thanks for your help,

I've found it in Qt4.4 : setActivationOrder(QMdiArea::StackingOrder)
but i'm still working with 4.3 so if anybody knows...
