Tooltips in the Datagrid

[Bob Sneidar]

I don't use fillInData. This works with a normally populated datagrid, otherwise I could have done that. The trick here is discerning what the LAST control being pointed at is, after a nominal delay, and then ignoring all the mouseEnter events that were queued up before that. Otherwise (especially in Windows) EVERY SINGLE CONTROL TOUCHED gets a 30 tick delay followed by the display of a tooltip, and that gets tediously old in a hurry.
