Analysis

Overview

Implementing a working Drag'n'Drop action for all the actions described in the requirement section:

• Dragging a resource to an empty space of the page work area
  • Image Resource
  • Text Resource
  • Audio Resource
  • Video Resource
  • Pdf Resource
  • Book Resource
  • Other
• Frames
  • From one book to another
• Pages
  • Page Resource from Resource Palette
  • Page Template
• Styled Text

Task requirements

• Dragging a page resource from the resources palette to the page should do nothing
• Dragging image resource to an empty space of the page work area should create a frame and link the resource in it
  • If an image resource is dropped over the padding space of an existing frame, it should replace it's background
  • If other resource is dropped over the padding space of an existing frame, nothing should happen
• Dragging text resource to an empty space of the page work area should create a frame and link the resource in it
• Dragging a book resource to an empty space of the page work area should create a frame and link the book in it
• Dragging an audio resource to an empty space of the page work area should create a frame and link the audio in it
• Dragging a video resource to an empty space of the page work area should create a frame and link the video in it
• Draggging a pdf resource to an empty space of the page work area should create a frame and link the PDF in it
• Dragging any resource to an empty space of the page work area or resources palette of another book should copy the resource to the target book. The resource should have the same name as it was in the previous boook.
• Drag'n'drop of styled text

To be discussed with analysysts and implementators:

• Dragging a frame (using titlebar) to another book should copy the frame (including contents) to the other book

Optional functionalities that can be achieved for this or left for the next revision are:

• Pressing CTRL before the drop forces copy instead of link
• Pressing Alt before the drop forces link instead of copy
• Reordering pages in page preview palette
• User should be able to embed a book by dragging book from open books palette to the current book.
  • The embedded book should be linked
  • When an inappropriate action is executed (e.g. trying to embed a book in itself) an adequate warning message for the forbidden action must be evoked.
• If one of the resources (text, audio, video, pdf, book) is dropped over the content of an existing frame, it should replace it's content
• Dragging a page (pages) from the page preview palette to the page preview palette should put the selected page(s) to the desired position
  • If the selection is not by neighbour pages, they should become neighbour and should be put where dropped
  • A highlight between pages should appear before dropping of the dragged page(s)
• Dragging a page template from the library tab over an existing page in the page preview palette should apply the template to the page it was dropped on
  • The target page should be highlighted before the drop
• Dragging a page from the resources palette to the page preview palette between pages puts the page in the page sequence (links it)
  • A highlight between pages should appear before the drop
• Dragging a page from the resources palette to the page preview palette over an existing page replaces the targed page with the dropped one (linked)
  • A highlight between pages should appear before the drop
• Dragging a page template from the library tab before/after an existing page in the page preview palette should create a new page from the selected template and put it where it was dropped
  • A highlight between pages should appear before the drop

Task result

• Task result should be code

Implementation idea

• See the related links
• Create Logic that handles import of different resources and remove all similar logics (ImageLogic, PdfLogic) that handle imports of resources.
• Improve drag'n'drop of ResourceReviosionData for drag'n'drop of resources between different books to be done.

How to demo

• Run Sophie2
• Create a new book and add frames with different resources in it
• Execute all the actions from the overview and see if they achieve the expected results
