Comment to chapter 13

[LNUitTutor]

p. 119 “and then build a little editor”, p. 127 “Defining a presenter for the Editor” – is it really an editor after “text beNotEditable”? The created application is at most a viewer for one fancy phrase. It is clear that the chapter is about styles, but this is nice occasion to talk about file dialogs: how can I choose a file to load it? How can I choose a file to save data to it?

pp. 122-123 So much code without explanation. How can I use it? For what? Unclear.

p. 124 “smalltalk textutal object notation” – should be textual.

p. 126 “label addStyle: 'black'.” – should be 'bgBlack'.
