Analysis

Overview

All frames have a frame anchoring halo which allows a frame to be anchored. This means that the frame will be associated with a particular point in another frame. There are different modes defining how the frame should move according to the frame it is anchored to.

Task requirements

• When a frame is selected the rightmost of the halos that appear over it should be the frame anchoring halo. It is going to be represented as a small anchor icon.

• The user should be able to drag the halo to the a place where the frame should be anchored.

• A subsidiary line should be drawn between the two frames. It should not be visible in Reader mode.

• When the anchoring halo is dropped an anchoring hud is displayed allowing choice between the different anchoring modes – CHARACTER, INLINE, LINE, PARAGRAPH, FRAME, PAGE.

Task result

The result of this task is source code.

Implementation idea

Add new halo to the frame halos. Create hud with the six different anchoring modes. Draw a line when the halo is dragged and open the hud when it is dropped.

How to demo

• Select a frame and show the anchoring halo. Drag it into another frame and show the line connecting the two frames. When dropping it show the anchoring hud.
