[pve-devel] [PATCH widget-toolkit 4/4] panel: add StatusView from PVE

Mon Apr 19 13:00:44 CEST 2021


with 2 minor fixups:
* one lint error
* binding of the 'updateValues' function in the event
  (we want to avoid breaking this when used in a context where
  a controller exists, in that case using a string will only look in
  the controller and not in the component itself anymore, so use
  the function directly)
