As I was looking for a multiple inheriting method with Qt, someone
proposed me the following solution:
class A(Qt1) :
def __init__(self, b, *p, **pp) :
Qt1.__init__(self, *p, **pp)
self.b_ = b
# wrap B methods (both defined in B and Qt2 classes) to current class
def method_1(self, *p, **pp):
return self.b_.method_1(*p, *pp)
def method_2(self, *p, **pp):
return self.b_.method_2(*p, *pp)
def method_3(self, *p, **pp):
return self.b_.method_3(*p, *pp)
class B(Qt2) :
def __init__(self, ....)
Qt2.__init__(self, ...)
a = A(B(...), ...)
I didn't make test yet; do you think it is a useable solution?
