show a tooltip on click, and keep it up until the pointer leaves

Browse Source 
One tooltip mechanism for the whole UI: a Tooltip popup plus a
TooltipTrigger event filter, replacing every setToolTip call. Qt's own
tooltip cannot do what REQ-UI-TOOLTIP-TRIGGER and REQ-UI-TOOLTIP-DISMISS
ask for -- it times out, hides on the first mouse move, cannot be hovered
and cannot be brought up by a click.

A tooltip now appears the moment an element with no click action of its
own is clicked, and it is placed with its top-left corner on the pointer,
so the pointer can move onto the tooltip and hold it open. The pointer is
polled while a tooltip is up rather than tracked through enter and leave
events, whose order depends on which widget the pointer crosses first.

The item chip's children become transparent to the mouse. They were
taking the chip's enter and leave events, so its tooltip only ever
appeared when the pointer rested on the chip's padding.

The modal header's close button loses its "Close" tooltip: a close button
in a header says that by being one.
