Analysis

Overview

The page structure palette shows a tree of all the objects on current page.

Task requirements

• Create a Page Structure palette in the Pages tab, which is in the left flap.

• Create a tree, according to the following requirements:
  • The root node of the displayed tree should be the current page.
  • Children nodes:
    • Non grouped frames (display the name, for example "Frame A")
    • Top-level groups
      • Groups are represented as a tree of frames and subgroups.
  • Children of frames are their resources.
  • Children are arranged by their Z-order, starting from highest (front-most).
  • For this revision it is not required the tree to allow editing.

• When the user selects something on the page it is selected in that tree and vice versa. TODO: also in the resource palette, but we should change the way items are selected
• When the user switches to another page/book, the palette is automatically updated.

• In next revisions nodes should have icons - for page, text, image, video, group, etc.

• The tree should allow expanding/collapsing of subtrees.

• TODO: things to consider ??????
  • templates - in Sophie 1 they are represented too, but in Sophie 2 they are different
  • chaining (how to display it?)
  • links, timelines, ...

Task result
