I want to make a Cocoa applictation using all code in Xcode, not using the Interface Builder. I have searched a lot on this and have not found anything since most people want to use the Interface Builder. Please don't say anything like "Don't waist your time on it", "They did the work for you, why do it yourself?", etc., like most people. When I make applications, I like to use all code. So, can you explain how to do this or post a link? Thank you very much for your help! I had this in C++, which was the …

What is the Windows equivalent of Cocoa from Objective-C? I'm thinking C++, but is there anything that includes an easier way to create a UI? (If there is an IDE that features a UI builder for C++, please mention) ((Sorry if you don't think I should've posted this here. Since it's software related, I figured 'Microsoft Windows' wouldn't be the best place to post it.))

From an exercise in a cocoa programming book I'm trying to make a to do list app that simply adds, removes and change the entries in the table. I have a lot of things wrong with it. relevant info: * add button: add entry with text from text field. If an entry is highlighted in the table the text is supposed to replace that entry, and it works. * remove: remove an entry. Shouldn't do anything unless a field is highlighted. Only removes the first entry. * int at: the selected row number, for add and remove button functionality. * …

If you always thought that OpenStep, Cocoa's base, was limited to Mac OS X, you're wrong. A project called [URL="http://www.gnustep.org"]GNUstep[/URL] is dedicated to creating an open-source implementation of the reusable objects that Cocoa uses. Cocoa, which is the framework that the vast majority of Mac OS X software developers use to create application user interfaces. It uses NextStep's framework to create reusable objects using objective C, which is not dissimilar to C# or Java. Carbon is another application framework that can be used to create Mac OS X interfaces, but the difference is that Carbon is more C-based, using a …
