Animation not working when collapsing subgraph #167

Closed ba2sik closed 2 years ago

ba2sik commented 2 years ago

Hello, If you look at this demo, when clicking + on Main1, the border/stroke around the items in the group, and the group header, is growing with animation, but when collapsing when clicking -, the stroke around the items and the header simply disappears, without doing it with animation.

Is it possible to override the closing animation somehow to make it work?

Thank you

?

WalterNorthwoods commented 2 years ago

Not easily. It might be possible to turn off that built-in animation and implement everything yourself.

This is not an issue (bug) in the library or samples or documentation, so this topic does not belong here.

Why is this not a bug? When expanding the group the border around the nodes is growing, and when collapsing the border disappears instead of shrinking. This is inconsistent behavior in the library...

WalterNorthwoods commented 2 years ago

Yes, that does appear to be inconsistent. However, that is how it was designed. I suppose an implementation alternative could be achieved by customizing the group's border computation to include not-visible member nodes during animation.
