File: PrintingTextView.m
|
|
Abstract: Very simple subclass of NSTextView that allows dynamic rewrapping/resizing to accomodate user options in the print panel when printing.
|
|
This view is used only for printing of "wrap-to-window" views, since "wrap-to-page" views have fixed wrapping and size already.
