currentFocusNodeIndexRange questions

[jfrux]

I suppose my real question is... does a "list" have to be "isFocusable" in order for "isWrapping" to work?

Hey @jfrux could you post all your example registerNode calls, and what you expect to happen for a given handleKeyEvent?

Generally speaking, isFocusable should only be set on the nodes that you actually want to have focus, i.e can "hold" a cursor on them. If you wanted, for example, a horizontal list that wrapped, the setup would be along the lines of

const navigation = new Lrud();

navigation.registerNode('root', { orientation: 'horizontal', isWrapping: true })
    navigation.registerNode('child_1', { parent: 'root', isFocusable: true })
    navigation.registerNode('child_2', { parent: 'root', isFocusable: true })
    navigation.registerNode('child_3', { parent: 'root', isFocusable: true })

Now, if you assign focus on child_3 and handle a key event for the direction of "right", you should find your focus landing on child_1. Does this help?

Okay, yes… that is what I would think should happen… unfortunately I wasn’t seeing that happening on mine like I had in 2.7.x What was happening is it was focusing the wrong index but was probably just my messy code.
