macOS Get NSTextView to trigger selector on key combination

[Chirone]

I have a NSTextView and I want something to happen when a button is pushed. That's a very trivial task to do...
I also want it so when someone hits shift+return the selector the button triggers get used.
how would i do that?

Set the key equivalent of your button to shift + return.

i imagine if the textview could actually give up it's focus that would work

but shift+return just makes new lines in the nstextview

If you want to handle it directly within the NSTextView, you can override insertNewline: in an NSTextView subclass:

- ([color=#aa0d91]void[/color])insertNewline:([color=#aa0d91]id[/color])sender
{
    [color=#aa0d91]if[/color] ([[[[color=#aa0d91]self[/color] [color=#2e0d6e]window[/color]] [color=#2e0d6e]currentEvent[/color]] [color=#2e0d6e]modifierFlags[/color]] & [color=#2e0d6e]NSShiftKeyMask[/color]) {
        [color=#007400]// do something[/color]
    } [color=#aa0d91]else[/color] {
        [[color=#aa0d91]super[/color] [color=#2e0d6e]insertNewline[/color]:sender];
    }
}

works perfectly!
thanks!

the insertNewline: function doesn't appear to be in the documentation...

NSTextView is a very complex and elaborate class. If you need to implement a behavior, you can look for a vector (method to override) in its superclasses and protocols (when the docs say an object conforms to a protocol, you can expect that it at least implements the required methods for that protocol). In this case, the method in question is in NSResponder.
