[vlc-devel] [PATCH 11/14] qml: recursively traverse disabled NavigableFocusScope

[Pierre Lamot]

  The previous behavior was to traverse sibiling until we find one a focusable
  one. This caused problem when the last sibiling in chain wasn't focusable as
  it was unable to continue with the parent sibiling.

  This allows to handle the case where a disabled focusable item is last
  in chain. It assumes items would behabe sanely when non focusable (have a
  sibiling or parent defined)
