= 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.

 * 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.

  * !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.
  * Change !DesktopPane class - from inheritance to composition of JDesktopPane.
