Viewport

Deprecated

The Viewport controller is no longer used in Kitto^x. It was the ExtJS full-screen container wrapper (Ext.container.Viewport). In Kitto^x, use BorderPanel directly as the top-level controller for your Home View.

Migration from Kitto1

Replace Viewport + SubView with BorderPanel at the root level:

Before (Kitto1):

Controller: Viewport
  SubView:
    Controller: BorderPanel
      NorthView: ...
      WestView: ...
      CenterView: ...

After (Kitto^x):

Controller: BorderPanel
  NorthView: ...
  WestView: ...
  CenterView: ...

Also rename any MobileSettings children:

Kitto1	Kittox
ViewportContent	Content
ViewportContentLandscape	ContentLandscape
