DirectButton bind() and extra args?

Scripting Issues
1

Can’t you have extraArgs in the bind() method, like this?

button.bind(DGG.ENTER, printbuttoninfo, extraArgs = [buttoninfos[buttonindex]])

I get some lenghty error message:

Yes, you can do this. This error message must be related to something else.

It’s somewhat concealed by wordwrap, but you have written:

extraArgs = [buttoninfos[buttonindex]]

So I’m guessing the error message is telling you that buttoninfos is not indexable, ie. it is not a list/tuple/dict.

It seems the arguments were in wrong order.
