  32  * LyXView - main LyX window

  34  * This class represents the main LyX window and provides
  35  * accessor functions to its content.
  36  *
  37  * The eventual intention is that LyX will support a number
  38  * of containing LyXViews. Currently a lot of code still
  39  * relies on there being a single top-level view.
  40  *
  41  * Additionally we would like to support multiple views
  42  * in a single LyXView.
