Listbox drop

I want to implement the Dragover event of a hierarchical Listbox. How do I relate the X and Y to a row/column?

Right! I couldn’t remember. Thanks!

Another thing is, I have two listboxes, one accepts multiple file drop, and the other doesn’t, Windows 7 shows a ‘prohibited’ sign, though they both have the same me.acceptfiledrop activated. What could cause that?

How lucky you are…

In Cocoa, no FocusRing nor MouseCursor change at all !
