I am revisiting an issue with which I had a problem earlier. I have a
detail view which is bound to my model in an NSArrayController. Currently, I
can edit multiple selections. What I want to accomplish is warn my users when
they are about to edit multiple items and give them the choice of whether or
not to do it.
Now users can edit an item 2 ways. They can tab into the control (in
this case an NSTextField or an NSComboBox) or mouseDown: into the control. I
want to basically interpose both ways of accessing a control. The minute they
try to click into a control, I want to perform logoc to determine multiple
selection and then thrown an NSRunAlert… that they are about to edit multiple
items.
Does anyone know of a good way to do this?
Thanks,
Patrick
