Hi Ross, thanks for replying. I wish I didn't have to subclass NSTextView, but from my understanding it seems like I have to.
Basically, the interface is separate editable objects that are usually single symbols with a few arguments included. This means that the each object is always one line high and usually not that wide. I started off using NSTextField (which I could resize easily) but I want to add syntax highlighting and auto-completion. From what I read NSTextView is the way forward. Thanks for the code, it does indeed resize for me. However it doesn't shrink when I remove text. >From poring over the Apple docs again ( http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TextLayout/Tasks/StringHeight.html) I managed to get my the NSTextView subclass to resize. However it doesn't redraw itself and looks weird until I change the size of the main canvas. Would you say I am taking the wrong approach? All I wish to do is to have multiple instances of an object each with its own resizable/auto completing text field as a subview.
