Analysis

Overview

Autochaining should be more stable

Task requirements

• Add an item "Autochain" in the chain dropdown and remove the autochain button.
  • The item may be italic in order to be clear that it is not a regular item
  • When autochaining is enabled, a template for this page is automatically added.
    • When the last page is modified, a new template is created automatically on creating a new page for the flow.
    • New pages appear with the layout of the last page in the chain.
• When the text overflows, a new page with the same layout is created at the end of the page sequence
  • The page may contain more than one auto chained frame
• When text is deleted and the flow no longer fills all of the frames on a page
  • If the page has local modifications, it is not deleted
  • If there are previous pages without local modifications, they are deleted (there should not be text from other flows)
• When autochain is created the last frame of the autochain should be with enabled autochain by default:
  • Create text frame paste. -> Text frame is inserted.
  • Paste text in it. -> The frame is filled with text (visual marker appears (optional)).
  • Click on autochain. -> New pages with same template are created.
  • Paste some text in the already created autochain. -> New pages with frames should be added after the last, because the text is overflowing.
• Optional - When a text frame is full and unchained, make a red glow to indicate that there is text that is not displayed
  • This glow should be visible in author mode only

Implementation idea

Make a single method that uses the dry run of HotLayout and recalculates the areas needed for the text flow. It should add or remove pages if necessary. When auto-chaining is enabled call this method whenever chainging the layout of the HeadTextFrameView.

How to demo

• First case:
  • Create a page
  • Set custom layout.
  • Insert an image frame
  • Insert a text frame, put enough text and autochain
  • Delete the text and show that pages are deleted
• Second case:
  • Create text frame paste. -> Text frame is inserted.
  • Paste text in it. -> The frame is filled with text (visual marker appears (optional)).
  • Click on autochain. -> New pages with same template are created.
  • Paste some text in the already created autochain. -> New pages with frames should be added after the last, because the text is overflowing.
