Giving an NSTextView some padding/a margin

Question

How would I give a NSTextView some padding/a margin to the left? I know how you do it in a NSTextField (by subclassing NSTextFieldCell) but how do you do it in a NSTextView?

Answer 1

The way TextEdit does it (when in Wrap to Page mode) is to put the text view inside of a larger view, and set that larger view as the document view of the scroll view. That's more work to set up, but won't leak presentation information (in the form of a specially-customized paragraph style) into the model (the text).
