Analysis

Overview

• Templates allow the user to create book elements suchs as frames, pages and books that have certain pre-defined characteristics.
• The newly created elements may override the properties of the template.
• Editing the template should update all objects that it is applied to.
• Locking a property, prevents any changes to it.

Task requirements

• Define a library that supports templating a pro-objects.
  • There should be a different behaviour for immutables and mutables.
  • Use composition instead of inheritance to prevent coliding with resources.
• Define a basic GUI in halos/huds for creating and manipulating templates and locking.
• Define frames, pages and books templates pallete in the library tab.
• The frame properties that need to be templated can be seen FRAME_TEMPLATES_R0
• The page properties that need to be templated can be seen at PAGE_TEMPLATE_BEHAVIOUR_R0

Task result

The result of this task should be source code.

Implementation idea

• The template and the element are an instance of the same class. For example, the template of a frame is also a frame.
• Properties that are templated should be defined as auto properties, which will calculate their values based on the template of the object.
• Page and frame templates should be global for each book.
• Book templates should be global for the app.

How to demo

• Start Sophie2.
• Create a page with some frames.
• Add the page as a template.
• Create another page and apply the newly created template to it.
