Okay, great, thank you. This seems to work fine for NSTextViews, but for my
NSTextField I now have a lot of other problems ...
But let's start from the beginning, this is what I did:
- I want to overide the TAB behaviour of an NSTextField (not an NSTextView).
- But an NSTextField is using "internally" an NSTextView for its text input.
- So I allocated a custom NSTextView object that I return in
"windowWillReturnFieldEditor:toObject:" in the NSTextFields delegate.
- In the delegate of my new custom NSTextView I override
"textView:doCommandBySelector:" and look for insertTab and
insertTabIgnoringFieldEditor to exchange the behaviour.
OK, so far.
But:
Now the NSTextField behaviour has broken! Normally it sends some
notifications (textDidEndEditing etc.) to its delegate when the user hits
Return, TAB etc. Now it begins a new line when I press Return for example.
Do I have to "mimic" the complete old NSTextField behaviour myself? How
would I do that? Or is there some "flag" somewhere I've missed?
I don't know how I can implement the same behaviour of the NSTextField as it
had before changing its NSTextView to a custom object.
As a first step I tried to call endEditing on the TextField's cell when the
selector "insertNewline:" should be called, but then the entered text will
always disappear ...
Any hints? An easy solution I haven't seen?
Regards,
Mani
