yes, as Marco pointed out.

but since we're looking at some re-work of the implementation anyways, it 
might make sense to give ToolTipContent the ability to have a set of items.

i see that System Settings is using a QAbstractItemModel here (or a subclass 
of that, didn't look further :) and passing in a QModelIndex. so perhaps 
ToolTipContent gets the ability to have such an index (perhaps a persistent 
index?) and that is then very easily used from QML.

this would allow us to do much prettier arrangements, including in places like 
the pager and clocks.

yes, we'll move to QML for all this.

i agree wit Marco's suggestion.. we'll need different mechanisms for different 
kinds of targets. and one would be written for QItemView that starts watching 
mouse events on the view when the view is hovered (and stops when it is 
unhovered)
