Well as usual a little Be Book reading provided a workable solution:
if (ToolTip()->View()->LockLooper()) {
dynamic_cast<BTextToolTip*>(ToolTip())->SetText(text);
ToolTip()->View()->UnlockLooper();
}
But this results in some weird behavior: the tool tip starts off empty
(maybe because the first call fails for a lack of a looper?) Then when
it is updated it is too narrow and never gets wide enough to show all
the text. Plus while the tool tip is showing the updating of the alpha
slider flickers a lot.
So I guess a better solution is needed, or bug fixes in the tool tip class.
