Clearing an NSTextView
-
Hey,
I have a small iTunes application and I am adding supporting the
display of lyrics. Now I have it set up just like I want it to, and it
looks amazing. Now the only problem is this:
When I use [NSTextView insertText:@"Lyrics Code Here"];, it doesn't
delete the current text so that is it is replaced for the user... So
after opening the lyrics for quite a few songs, it is a bundled up
into one long set of lyrics. I looked at both NSTextView and the
classes referenced by the insertText documentation. So how can I
remove all the current text and replace it using insertText?
Thanks,
Jeremy

Why would you believe "insert" means anything but? If you read the
documentation on the text system, you'll get a better idea of where to
look for more answers.
You can ask the text view for its NSTextStorage (which is a
subclass of NSMutableAttributedString) and replace the contents with -
replaceCharactersInRange:withString: or -
replaceCharactersInRange:withAttributedString:

I knew insertText: wouldn't remove the text. I just can't figure out
how to remove it all. And how do I select all of characters? That
would be my only problem with the
replaceCharactersInRange:withString:...
Thanks,
Jeremy

Of course this works too. :-) The caveat is that if you have
formatting applied, this may interfere. There are similar NSText
methods such as -replaceCharactersInRange:withString: and the like.
These also give no control over formatting.
If you're worried about preserving formatting (when you have
"allows multiple fonts" enabled, etc.) you'll find it easier to modify
the underlying NSTextStorage.

Did you read my previous e-mail? See also the e-mail from Gary. The
approach you take depends on whether you're using any attributes
(formatting). If it's all the same font/size/etc. then setString: will
do just fine ... just set it to:
@"";
... and it's empty.> And how do I select all of characters? That would be my only problem

-setSelectedRange:?

Sorry, I misunderstood your question. Why would you need to
'select' the characters to use -replaceCharactersInRange:withString:?
You give it the entire range of the text currently in the text view
and a new string to replace it with.
No selection necessary if none is desired ...

IS,
Thanks for the setString:. I believe I tried that before and it didn't
work. It is now working as intended.

Thank Gary for that - I didn't even think about it until he
mentioned it because for some reason I was thinking of "maximum
control" (assuming formatting). I'm a bit of a control freak ... ;-)

Personally, I didn't get an e-mail from Gary on this subject. I'm sure
one was sent but I only have e-mails from you IS...
