- Since
- 4.4 Register a debug area dynamically.
- Parameters
-
areaName the name of the area enabled whether debug output should be enabled by default (users can override this in kdebugdialog or with DisableAll=true in kdebugrc)
- Returns
- 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 set KDEHOME), 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).
