Just call textShouldEndEditing inside your shouldSelectTabViewItem
method and return the value returned from textShouldEndEditing.

I have a NSTextField inside a NSTabViewItem with a delegate that
responds to textShouldEndEditing. If That succeeds the NSTextField
performs an action (which saves the information the user entered). If
the user enters invalid information then textShouldEndEditing presents
a
sheet telling the user to fix it and returns NO.
However, if the user clicks on a different tab after entering invalid
information, the sheet pops up but the tab still changes. How can I
use
tabview:shouldSelectTabViewItem delegate to catch this event and
prevent
the tab from changing if the user has entered invalid data? It appears
that tabview:shouldSelectTabViewItem is called before
textShouldEndEditing. Is there a way to reverse this?
Essentially, I want to block all other events until
textShouldEndEditing
returns YES.
