45 * LyXView - main LyX window
47 * This class represents the main LyX window and provides

50 * The eventual intention is that LyX will support a number
51 * of containing LyXViews. Currently a lot of code still
52 * relies on there being a single top-level view.
54 * Additionally we would like to support multiple views
55 * in a single LyXView.

69 * before we can populate it with this call.

90 there is only one lyxFunc() for now but there is maybe a need
91 for more in the feature. Something like that:
93 LyXFunc & getLyXFunc() { return theApp->lyxFunc(id_); }
95 where id_ would be the this LyXView ID.
96 That's the reason why I didn't remove these methods for now.
