[Cdk-user] Making JChemPaint a CDK subproject

[Christoph S. <c.s...@un...>]

Hello everybody,

JChemPaint (JCP), our 2D chemical editor, has recently experienced=20
increased development activities from various sides.
While these new development efforts are highly laudable, people have=20
also recognized that - in the long run - central modules of JCP need a=20
redesign and -write with a cleaner and more modular architecture. This=20
mostly effects the controller and the renderer, not so much other add-on=20
chemoinformatics functionality from CDK.

Neccessary changes include (but are not limited to)
- moving to a clearly defined finite-state machine,
- encapsulation of *all* user-invokable functions into action classes to=20
enable the implementation of a clean redo-undo functionality, and
- design and implementation of a model for fully reversible on-the-fly=20
transformation from screen to atomic coordinates, including a model for=20
handling zoom operations.

In order to make the development of this new implementation easier, we=20
think about moving *all* of the JChemPaint code into the CDK package=20
hierarchy. This would greatly reduce the complexity of the debug cycles.
Additionally, this move would actually just consolidate the current=20
situation, where virtually all but the application and applet wrapper=20
class are CDK modules anyway.

This plan is open for discussion. Any comment is highly welcome.

Cheers,

Christoph
