In a tiny document-based Cocoa app for Snow Leopard, I have a document
window with two NSTableView objects, which get properly feeded by
NSTableViewDataSource according to the documentation. Both table views
show simple arrays of one column each.
I can fill both table views with random content as I like to and even
drag and drop inside a list, with perfect refresh of the relevant table
view. But I would like to sync both table views somehow.
Here are my two questions:
1) Which delegate can I use to inform table view B to update and reload
its data when I have dragged an item inside table view A?
The NSTableViewDelegate methods don't seem to really help me here; I
tried them all.
I could of course add any "Refresh" button or stuff, but I would like to
refresh NSTableView B as soon as a row item of NSTableView A has been
successfully dragged into a new position.
2) How can I prevent drag operations from table view A to table view B
(and vice versa)? List members shall only be dragged inside their own list.
Can you give me a hint how to do this?
