cocoa tooltip delay per object?

Question

According to this article, you can change the tooltip display for your applications by modifying the NSInitialToolTipDelay user default.

So far, this seems to be the only way I have found to modify how long it takes to display a tooltip, however it seems to be application wide.

Does anyone know of a way that I can modify the tooltip speed for one specific NSTableView?

Answer 1

After a minimum of investigation my best (untested) suggestion would be to use mouse tracking regions (mouseEntered: / mouseExited:) along with [[objc_lookUpClass("NSToolTipManager") sharedToolTipManager] setInitialToolTipDelay:0.1]; (as suggested here: http://lists.apple.com/archives/cocoa-dev/2003/Jan/msg01219.html) to (re)set the delay when the mouse enters/exits the NSTableView's rectangle.
