11 months ago definition of a group:
- specific elements belonging to the same group
- elements move together
- elements distance to each other is static
- elements connections to each other can't be broken
- elements can be modified individually
- a group can intercept events and filter them before they are send to the elements
Analysis
Current State
As of v 1.9, groups ... are not groups.
A group is a trait shared by different objects.
The trait is stored in an array, that lets us stack and unstack traits, IE we can group on multi level, group multiple groups together and later ungroup.
As groups are not objects, we need to handle the objects and their grouped attribute instead for managing the group as an element. An example is aligning objects, groups need to be handled specially.
Elements in a group are static, particularly arrows.
