Re: Should delta raise exception when not available?

[Fred Kiefer]

Sorry Banlu,

I missed this second mail. This explains my stupid question.
I had a short look at the Apple documentation and you are right, it
doesn't state what happens when this method is called on the wrong event
type. Most likely we jst extrapolated the behaviour from the other
methods on NSEvent. The better way to find out is of course to write a
short test program on Cocoa and implement the same behaviour.
I will do that and add this to our test suite.
