Add new overload to register_property_r/rw
New overload doesn't take initial property values as parameter, instead
getter function result is used to set stored reference value. This
approach prevents situation when initial value can be different than
value returned by getter function which can cause signals to missbehave.
Tested:
- Changed examples register-property.cpp and get-all-properties.cpp to
use new overload. Examples are working as before.
