Analysis

Overview

In this revision most of the work is to provide support for book extra elements. Annotation sets will be defined as book extras.

Sophie 2 should support three kinds of annotations:

  • Stickies - electronic version of the well-known sticky notes that you can put anywhere on a page.
  • Highlights - user can highlight parts of the text.
  • Audio annotations - user can record his own voice to make annotations.

Task requirements

  • Book Extras support
    • A book extra is a resource.
    • Book extras can be part of the book as any other resource, but they can also be just open along with the book.
      • For example, you have a book and you open annotations, saved in another file. They are displayed with the book, but they are not part of it.
    • A BookWindow should contain a book and a list of book extras (which can be empty). Some of the extras are displayed, the rest are hidden.
    • User should be able to:
      • Show/hide book extras
      • Open extras from file (for this revision - only add dummy extra to the list)
      • Add selected extra to the book resources or remove from there
      • Close selected extra - remove from the book window
    • The page work area should contain a list of extra PageElements.
      • Create an extension point for page element view providers.
  • Annotations
    • User should be able to select current annotation set. When he creates a new sticky, it should be added to current annotation set.
    • Stickies
      • Should be displayed in the scene of the page. Be sure that they are positioned and zoomed correctly.
      • In the upper right corner there should be a remove halo button.
        • If the sticky contains some text, a confirmation message should appear ("Are you sure you want to delete this sticky?").
      • The title bar of the sticky should display their creation date and time in users local short format.
      • User should be able to create a new sticky.
    • Audio annotations
      • Should be displayed in the scene of the page with appropriate image and creation date and time.

Task result

Source code.

Implementation idea

  • Create an abstract class BookExtra which extends Resource.
    • Add abstract method which returns all PageElements that this extra provides for current page.
  • Create two lists of BookExtras in BookWindow:
    • all book extras that are open for viewing
    • shown book extras - subset of the above. This list contains the extras that are actually displayed.
  • Create an extension point in MainViewModule for PageElement view providers.
  • Add a list of extra PageElements in PageWorkArea.
  • Create a new module - org.sophie2.extra.func.annotations

(Add links to related tasks that could be useful or helpful.)

How to demo

  • Open Sophie 2.
  • Open All Annotations tab.
  • Create a new sticky.
  • Go to Book Extras palette in Resources tab.
  • Select "My Annotations" from the list.
  • Click "Hide selected extra" button. The sticky should disappear.
  • Click the button again (now it's named "Show selected extra". The sticky should appear again.

Design

  • Book Extras
    • Create an abstract class BookExtra which extends Resource.
      • Add abstract method which returns all PageElements that this extra provides for current page.
    • Create two lists of BookExtras in BookWindow:
      • all book extras that are open for viewing
      • shown book extras - subset of the above. This list contains the extras that are actually displayed.
    • Create a Book Extras palette in Resource tab. It should display a list of:
      • all extras in BookWindow and
      • all resources in the book which are instances of BookExtra.
    • Create an extension point in MainViewModule for PageElement view providers.
      • Its interface PageElementViewProvider should contain methods getElementClass() and ScenePageElementView getSceneView(PageElement).
    • Add a list of extra PageElements in PageWorkArea.
    • Create an auto list in ScenePageWorkArea which contains the ScenePageElementViews of all extra PageElements.
    • In AuthorPageWorkArea and ReaderPageWorkArea add the scene elements of the extra elements views.
  • Annotations
    • Create a new module - org.sophie2.extra.func.annotations
    • Create classes Sticky, Highlight and AudioAnnotation, which implement an interface AnnotationElement.
      • Stickies have the following properties:
        • text : String
        • title : String
        • page : Page
        • date : Date - creation date and time
        • color : ImmColor
        • bounds : ImmRect (location and size; derived from PageElement)
        • parent : AnnotationSet
    • Create a class AnnotationSet, which extends BookExtra.
    • Create instances of PageElementViewProvider for stickies and audio annotations.
    • Create Scene views of stickies and audio annotations.
      • Stickies should be rendered as yellow semi-transparent rectangles with title bar
    • Create an Annotations tab in the right flap.
    • Create an All Annotations palette. It should display a list of all annotation sets. User should be able to select current annotation set.
    • Create a Stickies palette. Provide a button for creating a sticky.
    • Create halo menu and remove button for stickies.
      • The location of this menu is the upper right corner of the sticky.
