new LayoutManager()

LayoutManager gathers all external events which would affect
the layout of the windows and redirect the event to AppWindowManager.


The height of the windows would be affected by some global factor:



  • The height of StatusBar.

  • The existence of Software Home Button.

  • The existence of Keyboard.


When the size state of one of them is changed, LayoutManager
would send system-resize event.
