| IsQuery attribute adds const only to header, not to implemention [message #1777638] |

Hi,
If a passive class is added as a parameter to a signal,
the parameter type is declared as const&.
So some member functions needs to be declared as "is query".
If I check "is query" attribute to a member function of a class (not capsule),
"const" is added the function in its header file.
int getFunctionConst() const;
But "const" is not added to the its body function as follows.
int ConstClass::getFunctionConst()
{ ... }
So compiling fails.
Thanks.

I'm not sure I understand. Passive classes do not have signals. Do you mean an operation?
Also, declaring the type of a parameter to be const& is not related to the operation being a query or not. Can you clarify what you mean? Perhaps with your model?
In any case, this doesn't seem to be related to the problem:

I've tested this, and indeed this is a bug. In fact, the problem seems to occur with capsules as well, not just passive classes.
Unfortunately I don't have a workaround at the moment.
I'll open a bug for this.
