Couldn't you just subclass my class? I don't think it's altering
anything besides adding tooltip handling.
and you have to mouse out and back in to get a different tooltip
Well, that's exactly what I was trying to avoid ... :)
I was specifically trying not to redo the tooltips in
reloadData since that gets called far too often (I think).
Hm. I'm not redoing anything in reloadData. I'm just invalidating the
tooltip rectangles. They get recalculated only when a cell is redrawn.
I think there are more actions than changing the number of rows and
resizing that alter cells. What happens when reordering columns? Does
resizing columns call viewWillStartLiveResize?
for (;i<numRows;i++)
[self addToolTipRect:[self rectOfRow:i] owner:self userData:nil];
Isn't this getting slow with large tables? That was the reason why I'm
calculating visible cells only, anyway.
bye. Andreas.
