Adding "disable" feature at node level

[joGrim65]

Hallo, I'm working on a tree where, when clicking on a leaf node of a branch, could follow an action to disable another branch. For me "disable" means: neither check nor selection... and naturally no drag and drop and any change admitted on a node and all its children.

Actually I found no way to do that... do you think could be a request/issue you could add/manage?

I think you could add a "disable" attribute on TreeModel and managed it on tree items that need that feature applied.

I think this could be a useful feature.

Thanks
