This appendix includes details of the user interface specification and implementation of the real-world script repository application demonstrated in Chapter 14. It is instructive insofar as it shows how you might specify your application for the UI designer. It also shows how a good UI designer can improve the specification based on appropriate considerations and then implement it accordingly. Notes from the designer are shown in italics.
The application is a Script Repository that allows users to paste scripts into a text field and stores them in a central repository database. Users can download scripts, and registered users can add scripts to the database.
The UI should be one screen, with subscreens that pop up depending on the activity of the user. For example, if a user clicks Login, he is presented with a dialog box with a Submit button that asks for his username and password. If a user clicks Register, he is presented with a registration box.
The Flash movie size should be about 800 x 600 so that it fills the entire browser window.
The main screen should always be in view and show all options available.
The main screen is composed of two sections: the main area, where all the screens appear and which occupies 90% of the screen, and the navigation bar, at the bottom of the screen. The navigation bar is composed of an administrative section (on the left) and a main navigation section (which automatically disappears when not in use). When the application loads, the main navigation section appears for one second to catch user's attention.
All the buttons (both in the content section and navigation) are displayed on a black background so they can be distinguished with ease.
The whole application is made with vector graphics so that it can be easily scaled to any dimensions.
