In Xcode 3.1, what is the minimum necessary to create a useable
subclass of NSTextView ?
(before adding/overriding methods)
Additionally, in IB, is there any effective difference from using an
NSTextView, selecting the text view within its scroll view and
changing its class (in the inspector) to that of the subclass (say,
MyTextView, for example) and selecting a custom view, setting its
class to MyTextView and then selecting Layout > Embed Objects In >
Scroll View ?
I'm aware of the usual caveats leaning toward delegation and
notification, but I'd like to do this as an exercise to better
understand the capabilities of subclassing NSTextView.
Even a link to a tutorial/walk through would be nice.
I've already read
Subclassing NSTextView
in the developer docs, but it does not quite show me everything, it
seems.
In the feeble attempts I've made, when running the app, the custom
text view places vertical lines where glyphs would be, and it does so
starting at wherever in the view you initially click...
