Analysis

^{(Give as much as possible of the needed information for designing and implementing the task in the following sections.)}

Overview

• Text frames should allow chaining between them. That means that when text overflows from one text frame it goes to another if they are linked. Also there should be overflow indicator.
• There should be opportunity for the user to have multiple flows from different text frames.
• The user should be able to point which text frame is linked with current flow and witch is not.
• There should be automatic linking when flow text frame is used. See more at TEXT_AUTO_CHAIN_BEHAVIOUR_R0
• If there are many linked flow text frames user should have the opportunity to easily reorder/delete/unchain them.

Task requirements

• Implement unchaining of frames
  • User should be able to unchain chained frames by clicking a halo button. There should be two halo buttons - one for unchaining next frame and one for unchaining previous frame. Halo buttons should have crossed arrow icon for now.
  • Unchaining frames creates two new chains. The text stays in upper chain.
  • If the frame is unchained via upper halo, it stays in bottom chain
  • If the frame is unchained via bottom halo, it stays in upper chain
  • If the frame is deleted, again two chains are created, but the frame is not part of them anymore.
• Implement editing of non-first chained frame
• Create appropriate halos
  • The halo buttons should be the same, but two halo menus are needed, one at the left upper corner and one at the right bottom, see Implementation idea
  • Since the text halo won't be where it is at the moment, remove it from there (move it to top right for example)
  • In the top menu, the unchain halo should be present when the frame is part of a chain
  • In the bottom menu, the chain halo should be present when the frame is not part of a chain. Otherwise, the unchain halo should be present.
  • See implementation idea for further details.

Task result

How to demo

• Chain five frames on a page.
• Show the halos - first frame should have only unchain (bottom right), others should have 2 unchain halos each (up and down), Last frame should have unchain upper halo and chain bottom halo.
• Unchain the third frame.
• Show that first 2 frames remain chained
• Show that last 2 frames remain chained
• Depending on how you've unchained the frames, explain where does frame 3 belong
• Repeat the steps but delete frame 3 instead of unchaining.
