QGraphicsWidget::geometryChanged is not emitted when setPos is called...Also it should be emitted after the resizeEvent....

KDE :

"QGraphicsWidget now has a geometryChanged signal in 4.7. Plasma::Applet also
has one. which means we'll need to conditionally compile it out in
libplasma. so far, not a huge deal.

but there are two problems with QGraphicsWidget::geometryChanged:

0) it is
called before resizeEvent is sent, which means that subclasses have no
chance to do any internal adjustments before the outside world is told that
geometry is changing

1) it only emits this when setGeometry is called. QGraphicsItem::setPos also
affects the geometry (in fact, setGeometry calls setPos internally), but
there is no signal emitted in this case. meaning that the "geometryChanged"
signal doesn't actually always get emitted when geometry changes.

:/

without touching Plasma::Applet, we have the problem of the signal being
emitted twice (once from QGraphicsView and once from Plasma::Applet), which
we can just compile out as mentioned above ... if only it worked properly

do you agree that this should get fixed in Qt?

and then i just need to
figure out how to make it so that we don't get these errors:

QMetaObject::indexOfSignal: signal geometryChanged() from QGraphicsWidget
redefined in Plasma::Applet

erf. hopefully QObject::connect is up to the task of connecting two signals
of the same name from two different objects in the inheritance hierarchy. i
don't have a good feeling about that.
