Documentation of class 'ThreeColumnTextView':
Object | +--GraphicsMedium | +--DisplaySurface | +--SimpleView | +--SyncedMultiColumnTextView | +--ThreeColumnTextView | +--Diff3TextView
a view showing two texts side-by-side. Scrolling is synced, by always scrolling both views. This type of view is especially useful to show diff-lists, code-versions, or other one-by-one viewable texts. Usually, it does not make much sense, to put totally different or unrelated texts into this kind of view. See subclass DiffTextView for a real class; see ChangesBrowsers compare operation for a real application of this kind of views.
