Description: This uses a matrix of radio buttons to delineate the progress of some routine similar to the way the Install application works. It isn’t great because it enables the radio buttons and thus makes them modifiable by the user but it shows how to access different rows/columns in a matrix. Keeping the radio buttons disabled doesn’t look right either. As an alternate, I’ve also used a series of text fields and modify their text color and content as the routine progresses to get a similar effect but without any chance of user interaction. This project also demonstrates the use of an autoscrolling text view which is very useful for logs.
