50 * LyXView - main LyX window
52 * This class represents the main LyX window and provides
53 * accessor functions to its content.
55 * The eventual intention is that LyX will support a number
56 * of containing LyXViews. Currently a lot of code still
57 * relies on there being a single top-level view.
59 * Additionally we would like to support multiple views
60 * in a single LyXView.
