The fix consisted of introducing "factory" type virtual
methods which ensure that a reference is held to the
returned object. This is important for implementing
factory methods in Python. Without this, the object
get destroyed before we have a chance to increment the
reference count.
- Include a copy of the unit test framework so we're no longer
depending on incompatible versions for Ruby 1 and 2.
- Avoid duplication of path entries in unit tests
With this change it is possible to bind signals to functions
accepting less arguments. For example:
def triggered():
...
b = pya.QPushButton()
b.clicked(triggered)
b.emit_clicked(True)
wasn't working before since triggered() gets one parameter
(checked) and the call fails. Now, additional parameters are
ignored.
