the area code that was allocated for this area

Typical usage: If all uses of the debug area are restricted to a single class, add a method like this (e.g. into the Private class, if there's one) static int debugArea() { static int s_area = KDebug::registerArea("areaName"); return s_area; } Please do not use a file-static int, it would (indirectly) create KGlobal too early, create KConfig instances too early (breaking unittests which change QStandardPaths dirs), etc. By using a function as shown above, you make it all happen on-demand, rather than upfront.

If all uses of the debug area are restricted to a single .cpp file, do the same but outside any class, and then use a more specific name for the function.

If however multiple classes and files need the debug area, then declare it in one file without static, and use "extern int debugArea();" in other files (with a better name for the function of course).
