Select and move a portion of a grouped path

If a portion of a grouped path is lassoed

• Only paths completely enclosed by a lasso are selected.
• Only that path is moved.
• Exit the group at the time of the move.

principle

• Grouped paths must move as a single entity without lassoing the whole thing each time
  • 
  • In this demo, they’re lassoed to show that they’re grouped together.
  • Grouping is automatic.
  • With the main use case “I use a pencil on my iPad”, I can write with the pen and move it as a lump with my finger.

Previous implementations

• 
• Selection by lasso only for top-level objects
• If you want to move only a part of it, you need to ungroup it.

---- discussion

If you select a portion of a grouped path, how should the movement of that selection behave?

Previous implementations:.

• Selection by lasso only for top-level objects
• So the gray “whole group” becomes the selection target, and the movement is also the whole group. Current implementation: (1)
• Child elements are also selected by a bug (shown in red).

In fixing this bug, should we stick to the “previous behavior” or not? Ideally, only “3” should work. What should happen after 3 moves?

• When you move the 3 farther away, that is clearly intended to be a different group than the “rest” so the group should be split.
• What if you moved them closer together? What if you made minor modifications to the placement of the elements in the group as they are?
• Should moved items be grouped?
  • There is a concern that simply grouping moved items into deeper and deeper groups

Wife’s opinion

• Only “3” moves naturally.
• I often see implementations where a group is chosen and ungroup is needed to move child elements, acceptable.
• When only “3” moves, it is unnatural for it to stay in the group
• Whether the moved items are grouped or not, ideally they should be, but even if they are not, it is acceptable.

based on this

• Move only “3.”
• 3” exits the group.
• Moved items are not grouped. “is” policy
