hm, don't think it would really work, since the qml for that would be 
something like
Text {
  text: "foobar"
  PlasmaCore.ToolTipData {
       icon: QIcon("konqueror")
       title: " foo"
       subtext: "bar"
  }
}

so having two ToolTipData children of Text is very useless (and with an 
undeterministic behaviour)
it could be useful indeed having another TooltipData for an itm that is a 
child of that Text {}

another approach would be putting the pointer to the widget in the tooltipdata 
itself, i dunno why it doesn't seem very elegant to me as a first glance but 
it would be way more robust:


Text {
  id:textItem
  text: "foobar"
}

 PlasmaCore.ToolTipData {
       item: textItem
       icon: QIcon("konqueror")
       title: " foo"
       subtext: "bar"
  }

yup, there is an 1:1 association between widget and tooltip for me as well :)
