Description
Trying to access sky region attributes from within Python gives an error:
>>> import gammalib >>> m=gammalib.GModelSky(gammalib.GModelSpatialPointSource(),gammalib.GModelSpectralPlaw()) >>> print(m.spatial().region()) <Swig Object of type 'GSkyRegionCircle *' at 0x1055168a0> >>> print(m.spatial().region().centre()) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'SwigPyObject' object has no attribute 'centre'while the following works
>>> r=gammalib.GSkyRegionCircle() >>> print(r) === GSkyRegionCircle === Right Ascension of centre .: 0 deg Declination of centre .....: 0 deg Radius ....................: 0 deg >>> print(r.centre()) (RA,Dec)=(not initialised)
Note that I have seen the same problem for other classes.
Recurrence
No recurrence.

Adding
%import(module="gammalib.sky") "GSkyRegionCircle.i";
in
model.i fixed the issue. So it appears that all derived classes need to be added to a Python interface when doing automatic type casting across modules. Here is the list of what I have identified:model.i:
%import(module="gammalib.sky") "GSkyRegionCircle.i";
%import(module="gammalib.sky") "GSkyRegionMap.i";
obs.i:

Note that the corresponding header files needed to be included to enable the compilation of the Python wrapper.
