Let's say the property is called "value". I called my setter _set_value,
pyuic inferred the setter's name to be setValue.

Does uic behave differently to pyuic?

I haven't used uic for some time, but this point is kind of moot since C++
doesn't have properties while Python does :) The point is that I can't see
that there is any reason for pyuic to try and use the setter method, when it
can simply use the property (i.e., obj.value = something).
