Analysis

Overview

This revision of the task will introduce CUT/COPY and PASTE operations for resources in Sophie2.0. It should also provide the implementation for clipboard operations with images(from, to and in Sophie2.0). If there is time left a prototype drag and drop functionality is considered to be implemented.

Task requirements

• Provide support for CUT/COPY/PASTE of resources.
  • From resource palette to the page work area.
  • From the page work area to the resource palette.
• Provide support for CUT/COPY/PASTE of images.
  • From an image frame to an image editor outside sophie.
  • From an image editor to sophie:
    • to the resource palette.
    • to the image frame - should change the image.
    • to the page work area - should create a new image frame.

Task result

• source code.
• Optional:wiki content with diagrams.

Implementation idea

• Create implementations of DndData for resources.
  • Either one DndData or multiple for the different types of resources. Depends on the design.
• Create implementation of SophieTransferable for resources.
  • Again may need only one transferable for resources or several.
• Note: If implementing clipboard operations for resources turns out to be a difficult thing, consider implementing only Frame clipboard operations.
• Put the ImageData into the created transferables to support transferring images if needed.
• Optional: (If not done, SHOULD be put for the next revision!)
  • Supply base classes for drag and drop management.
    • Create a global drag and drop manager that will handle part of the drag and drop operations. The rest should be handled in the corresponding logic.
    • Create DndData implementations for resources.
    • After creating the drag and drop base classes, implement D'n'D for:
      • images
      • plain text
      • resources.
      • Note: This should be rather easy having in mind that we have already implemented the necessary DndDatas and SophieTransferables...
    • Provide a diagram of the D'n'd manager.
    • Create a wiki page named BASE_DND, to serve as a reference for all drag and drop and cut/copy/paste functionality. It should have all the design of the base library, as well as the already implemented functionality. For example explaining the use cases that are implemented.
  • Create a DndManager class. It should be able to provide the interaction between VisualElements.
  • Create the diagram using netbeans and put it in the newly created page. Put also the wiki content of the previous revision of this task.

How to demo

• Use case 1:
  • Start sophie.
  • Drag and drop or cut/copy and paste an image frame from sophie2 to an image redactor. (for example gimp).
    • The image from the image frame should appear in the redactor.
  • Drag and drop or cut/copy and paste another image from the image redactor to sophie.
    • This should create a frame with an image content if dropped on the page.
    • This should change the current image of the image content if dropped on an image frame.
• Use case 2:
  • Start sophie.
    • Create some frames.
    • Drag and drop or cut/copy and paste a frame resource from the resource palette to the page work area.
      • The corresponding frame should appear as a copy of the selected one.
