Re: Tool tips in NSTableView

If I had to bet, I'd pick (a).

I hope you are right ;) I'll try it out - but I found another big caveat:

the tooltips are based on static rects. This is in a static nstableview. But it is already a problem in a static NSOutlineView, where the user can expand/collapse folders at will. This would cause many, if not even all cells to change their position.

So whenever data is add/removed from the view, or whenever a folder is expanded, collapsed, I would have to remove many many tooltip rects, and re-add them

Not only is this complicated, it requires me to hook in in multple places just to determine these changes occured; I don't even speak about the vast overhead.

To me it looks as if Apple really should add some direct support for this - I think what I want to achieve is not very unusal, is it?

it seems a simple delegate function could be added for this. Something like


- (NSString *)tableView:(NSTableView *)aTableView
toolTipStringForTableColumn:(NSTableColumn *)aTableColumn
row:(int) rowIndex;


and something similiar for outlineview...


Or maybe I once more overlook something obvious, and there is already a simple way to achieve what I want directly ;)
