I'm getting

QObject::connect: Incompatible sender/receiver arguments
        AddressWidget::showComponent(PilotComponent*) -->
QWidgetStack::raiseWidget(QWidget*)

when running KPilot; the warning is correct since I call

        connect(p,SIGNAL(showComponent(PilotComponent *)),
                fManagingWidget,SLOT(raiseWidget(QWidget *)));

*however*, PilotComponent is subclassed from QWidget, and as far as I can 
tell this works fine. I'm worried whether this will break in future Qt 
versions, and/or if there's a way to switch the warning off for this one case 
(I could, of course, add a slot that takes a PilotComponent *, and it'll be 
safe for sure, but that's more code for kde-devel to review :| )
