In case you have any idea how I could avoid this, I'd be happy to
change my code. :)
Well, the best thing to do is to log a bug when you are forced to
override private API like this; that way, we can try to provide a
public way of doing the same functionality. Unfortunately, I don't
have any suggestions to avoid this, based on what you want to do (and
I figured these were the ones you were talking about)
And beware that your app may break if you override private methods.
I know.
But in this case, the worst thing that could happen is, that the
column configuration is not saved any more.
What if AppKit adds a "hidden/setHidden" property on NSTableColumn?
I can cause compatibility problems, since the framework may start
accidentally calling your method.
Well, I guess that would hide the column - which is all the point,
no? :)
Well.....yes, but there could be problems. 10.3 introduced isHidden/
setHidden on NSView which started to cause some issues in existing
apps that had a "setHidden".
Seriously though. If that functionality was added to NSTableView/
NSTableColumn, I'd just have to update my code. That's not really a
problem for me. But I realize it could be a problem, if there were
many projects that used this code - this is one reason I hadn't made
it public yet.
Hm. I might look into a way to disable my implementation if the
superclass already responds to that selector.
If you don't mind re-releasing your app on updated versions of the OS,
then it isn't that big of a deal. However, users who upgrade before
you do may not be happy. ;)
Err... so, let's assume Apple added the functionality to NSTableView
to show/hide certain columns ... do you think -hidden and -
setHidden: would be added to NSTableColumn? :} If I knew that, I
could adjust my code to account for that possibility.
Well, take a look at NSView's isHidden/setHidden. That is the general
pattern we use for hiding stuff.
thanks!
