The initAt method calls the superclass s initializer with the specified coordinates and 1-by-1 dimensions. You can then call clear, which always resets your button list to empty, a perfect starting value. It then calls setup to appropriately size things. I ll talk about that more in just a bit. The add method is no more complicated. It creates your button, saves the callback in the special representedObject slot for NSButtonCell, and instructs this cell to send messages back to the ChoiceBar. You don t want to automatically invoke setup from add like you do with clear. This is because you ll usually be adding several buttons at a time to the ChoiceBar and resizing it for each of them would be a waste. Instead, just always call setup after you ve finished adding buttons. The clicked method will handle any mouse clicks on the buttons. Because the argument passed into clicked is the ChoiceBar itself (not the NSButtonCell), you ll need to use the selectedCell method to figure out which cell was clicked on. So what does setup look like It s a little hairy.

At this time of this writing, a number of users were complaining of having issues authenticating through RESTful authentication and were proposing a workaround of making the following modifications to the login required method in /lib/authenticated_system.rb. Advocates of the modification suggest changing it from this: def login_required username, passwd = get_auth_data self.current_user ||= User.authenticate(username, passwd) || :false if username && passwd logged_in && authorized true : access_denied end to this: def login_required username, passwd = get_auth_data if self.current_user == :false && username && passwd self.current_user = User.authenticate(username, passwd) || :false end logged_in && authorized true : access_denied end You can read more about it at http://www.railsweenie.com/forums/3/topics/1258 if you encounter similar issues.

The first line just sets the NSMatrix subclass s dimension to be one cell high and as many cells wide as required. You then place each ButtonCell in the appropriate location in the NSMatrix subclass. The last chunk of code sets the appropriate cell and frame dimensions for your NSMatrix subclass. If it doesn t have any buttons, it can go back to the old 1-by-1 dimensions and not worry about the cell size. If you have buttons, though, the code first needs to find the size of the biggest button. Then it ll use that as its cell size and to calculate the total size of the frame. All you need to do to start using the ChoiceBar is replace the following line in your CocoaTBS#initialize method

In this chapter, we explored the basics of what RESTful applications are and why there s so much buzz about them within the Rails community. We even built our very first RESTful application in Rails using the scaffold_resource generator. As a result, we now have a web application where we can enter all of our workout results. In the next chapter, we re going to develop another iteration of this application by further enhancing the interface design, integrating reporting capabilities using several popular Ruby graphing libraries, and adding some additional MIME types that can be called through the RESTful interface.

with this line:

This specifies the output format for the video. Possible values are as follows: xvid svcd vcd dvcd dvd divx asf mp3 psp ipod The names of these modes are not case-sensitive. These modes depend on you having the right libraries installed to make transcoding for that mode work, though. The rest of the examples in the following sections will use the psp output mode.

@bar = ChoiceBar.alloc.initAt(OSX::NSPoint.new(0, 0))

n the previous chapter, you learned about RESTful development as we built a basic exercise tracking application in Ruby on Rails. Unfortunately, we left one glaring hole in the application the inability to review our results in a meaningful way.
