Just added the attachment class to github as module
And added two more attachment classes, one for ComboBox (working) and one for a RadioButtonGroup (in progress). If someone has a clever idea how to design the lookup between the radio buttons and the ValueTree, let me know.
Now I can cleanup my code as well a bit…
I think it should be kept separate. Every AudioProcessorValueTreeState is a ValueTree, but not vice versa. So why would one restrict the users from using the attachment on “normal” ValueTrees?
@jules: if you want to add that stuff, please go ahead. But you probably will rewrite most of it anyways
