Document with Multiple Windows


  • Subject: Document with Multiple Windows
  • From: Mike Rossetti <email@hidden>

After searching the documentation and the list archives I'm still looking for a solution to a nagging little problem: Having a (Core data) document that has multiple windows, all of which should represent the documents dirtiness and support saving and undo/redo.

This document has a master-detail relationship. The main window lists and allows the creation, editing and deleting of the master components. Additional windows can be opened for the items in the main window and are used to create, edit and delete sub-components. (Imagine purchase orders with line items.)

I'm close: I can make edits in the main window and see them in the sub- component windows, and vice versa. But only the main window shows dirtiness and can be used to undo/redo. The additional windows can save the document but if I try an undo then I just get a beep.

It would be nice if there was a simple example of how to do this. Aside from that, does anyone have any suggestions?

Thanks,
Mike
