graph

In the printed book only three distinct colors are used in the grap making it impossible to determine which part of the graph is for which value. RM and G are the same color. R and GM are the same color.

Figure 22-1 and text above

The class "Subject" in the diagram has two times the method "attach(Observer)". One of them should actually be "detach(Observer)".

Also the text above the figure mixes the classes "Observer" and "Subject". It says "The observer class provides three important methods." It should be "The subject class provides three important methods.".

code block and following text

The code block gives two function definitions with respective signatures

py_new_Range_object (GnmRange const *range)

and

py_new_RangeRef_object (const GnmRangeRef *range_ref)

and claims: "The more subtle difference concerns the parameters: in the first function, the parameter is a constant pointer to an object [...], whereas in the second it is a pointer to a constant object." This is false, both cases declare the parameter to be a pointer-to-const, just using slight syntactic variation.

(I checked back at <http://ftp.gnome.org/pub/GNOME/sources/gnumeric/1.6/gnumeric-1.6.3.tar.bz2> that this is an error of the authors of the given chapter, not an error in copying the original source code into the book. However, the copied source code also contains a typo that is not in the original source code: a "(" is missing after "PyObject_NEW" in the definition of the second function.)
