Analysis

Overview

The book desktop is an improvement of the workspace introduced in Sophie1. It is a work background but with the features of a book.

• Desktop covers the whole work area and can be overlapped by flaps.
• Desktop has its own resources which can be used in other books
• Resources can be dragged from and to books desktop
• Minimize all books shows the book desktop
• Probably timelines won't be needed in the book desktop
• Scrolling behavior will remain the same as in the other books - scrollbars where needed
• The Desktop book doesn't have it's own book window - it uses application window as a book desktop.

Task requirements

• Create the book desktop concept
  • Document where it will be stored, how to be reset, etc
• Implement the Book Desktop
  • A book that covers all of the workspace - The book window of the desktop should be with dynamic size and centered to the workspace.
  • Probably autosaving on change should be present
  • Scrollbar behavior - scrollbars are present if there is an element outside desktop window bounds.

Task result

The result of this task is code.

Implementation idea

• Create a book with changeable size
• The book must be with enabled autosaving
• Document where is it stored, etc.

Design

• Overview
  • The book desktop is the component that is behind all books that are open.
  • The book desktop is a book with one page.
  • The book desktop is the book that is current when all of the open books are not current.
  • When it is clicked on the desktop, then the desktop becomes current.
  • When the user inserts a frame, the frame appears on the current book.
  • When the current book is the desktop, then all frames that are inserted appear on the desktop.

• The design
  • DocumentView - Base class for desktop book view and book windows.
  • DocumentWindow - Interface for document windows. DocumentWindow is a component that represent an open book (different from desktop book).
  • DefaultDocumentWindow - Base DocumentWindow implementation.
  • BookWindow - Contains common properties to BookDocumentWindow and BookDesktopWindow.
  • BookDocumentWindow - The main implementation of the DocumentWindow.
  • BookDesktopWindow - The component that represents the desktop book.
  • A property desktopBook() in App class that represents the model of the book.
  • A property desktopView() in AppDocumentsDesktop.
