|

// make python usage easier, but python can handle it if we pass CDmeQuadV3s

// Remember that only attributes can be saved and have undo support.

// If you want to add members to a Dme element which are not saved and
|
||
// never need undo, you can either use normal non-CDma members,
|
||
// or mark attributes to not be saved. In this case, I make the
|
||
// selection state be an attribute to get undo but mark the selection
|
||
// attribute to not save it to the file.
