46 * LyXView - main LyX window
48 * This class represents the main LyX window and provides
49 * accessor functions to its content.
51 * The eventual intention is that LyX will support a number
52 * of containing LyXViews. Currently a lot of code still
53 * relies on there being a single top-level view.
55 * Additionally we would like to support multiple views
56 * in a single LyXView.
58 class LyXView : public boost::signals::trackable, boost::noncopyable {
65 void setWorkArea(frontend::WorkArea * work_area);
68 * This is called after the concrete view has been created.
69 * We have to have the toolbar and the other stuff created
70 * before we can populate it with this call.
