POSubclassing a NSTextField
text
Body
copied!<p>First off; I'm a COMPLETE newbie at Cocoa, so please bare with me for asking what I am sure is an inane and utter newbish question. </p> <p>My situation is as follows: I want to expand on the functionality of NSTextField. AMong the things I want to achieve is:</p> <p>Changing the look and feel of the caret.</p> <p>Detecting when the text reaches a certain number of characters and then coloring the text after that limit differently. *</p> <p>To my great frustration after spending quite some time googling I find hundreds of hits that simply state "Sublass NSTextField and use this code.", and to my humiliation I have found myself unable to grok exactly how to do this. </p> <p>I would be extremely grateful if someone could give me a working example of a subclass that achieves one of the two things I list above, and instructions* on how to implement the code so I can try and figure out how it works by looking at some actual live code.</p> <hr> <h3>I am extremely apologetic for my late response!</h3> <p>Apologies to all of you. I have a colic infant at home, and as you (or at least those of you that have children) can imagine this takes up quite a lot of your available time. Thank you all for your responses.</p> <p>I see that one of my main problems is that I don't have a sufficient understanding of delegates and outlets. I have purchased the book recommended here (and many other places. Some sort of "Bible" I gather) and I'm looking into it as we speak in the few silent hours I have these days. :) </p> <p>But although I can see it's going to be an indispensable tool for me I still gain the most understanding from studying examples rather than reading the theory* and so I would be extremely grateful if someone would create a project with a proper subclass of the relevant class since I understand that I should probably not be extending the NSTextfield class?</p> <p>I would instantly mark Mark Thalmans post as the answer as I'm sure it's a proper "for dummies" response, but I'll hold out for a few days since I'd really love a file to peruse. But I am not ungrateful! </p> <p>Oh, and; Please believe me guys when I say I'm not quite as useless in languages I actually know. It's just that these concepts with the Interface Builder and GUIs connection to the code is very unknown to me. I usually just write the code and keep it at that.</p> <hr> <p>*Yes, my first little training project is indeed a Twitter Utility.</p> <p>*Like to a child</p> <p>*Not that reading the theory hasn't got tremendous value for me as well. I wouldn't be where I am without Colin Moock definitive guide to AS3</p>
