Re: NSTableView: which delegate after a drag operation?
Hi Scott and Corbin. 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? 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. Thank you all for your suggestions and hints. I could now solve these problems. ---Ulf Dunkel ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hi Scott. 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? If you’re adding it to the object array, you can easily do the update notification then. [..] what do you mean here with "the object array”? If you’re adding the dragged data to your target table, that’s a good time to provide some notification that it needs to be updated. I only allow rows in NSTableView A to be moved inside A, or rows in NSTableView B to be moved inside B. But when a row in A has been moved, I want B to load and show updated data. I really don't know which notification or delegate to use for this. Can you give me a notification example, please? ---Ulf Dunkel ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Maybe this is just a stupid question, but what > do you mean here with "the object array”? No stupid questions, just incomplete answers. :-) If you’re adding the dragged data to your target table, that’s a good time to provide some notification that it needs to be updated. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

List members shall only be dragged inside their own list. You can pass NSDragOperationNone if the target is the originating table. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
