Analysis

^{(Give as much as possible of the needed information for designing and implementing the task in the following sections.)}

Overview

• Links allow the user to add interaction between different pages, page elements or frame contents.
• When a specific event happens with a source then the corresponding action is taken.
• The appearance of elements with defined links may be different in different states of the link.
• LINKS_COMMONS_R0? has more on this issue.
• Links have effect only when opened in sophie reader or when in preview mode.
• Changes done by links are not to be persisted.

Task requirements

• Define a model for links - how will triggers and actions be represented.
• Define how links are to be made part of the book and persisted.
• Define how different styles will be represented.
• Define a GUI for manipulation of links.
• Define some basic link triggers and actions.(look at subtasks for details)
• Text links(when triggering events are performed on text content) are not mandatory for now.
• Some additional tasks should be done - the preview mode of the book and the interactivity of scenes.

Task result

The result of this task should be source code.

Implementation idea

• Define the Link as a list of LinkRules
• The later are pairs of (Trigger, Action)
• Actions are a class hierarchy
• Define an OperationR3 that will handle all the links in the application instance

How to demo

• Run Sophie2
• Make a book with two frames
• Add a link to the first frame that on some action toggles the visibility of the second frame
• Switch in preview mode
• Perform the triggering action several times to demonstrate the showing and hiding of the second frame.
