I'm connecting some buttons in PyQt4 into the same function, this function will look up for the match between the Button name or title and a Class instance method name what manage different operations.
I'm getting in different ways the class instance methods into a list, iterate over and try to connect its respective function to its button. but i can't make work the method callback() in any way.

mirrorButton.clicked.connect(self.operations_module)

# Text gives me the name to Match ------------------#

#method(Sel_list) # Does not return anything, the process of the funcion gets an
# error at the very beggining of the method process
""" option 3 """
for meth in member:
if text.strip().lower() in meth[0].lower()[:]:
meth[1](Sel_list) # Gets the memory address of the function. Good. as a bound method
# Same result as option 1 - # NoneTypeObject is not iterable. no data sent.

the matching goes fine, the problem is calling the functions. what im doing wrong?
I don't know the OperationsRig class definition, so I define one by myself.
Since it could successfully match, I think it is not the problem of pyqt.
Here is my code:
class OperationsRig:
def foo(self, msg):
print('foo:' + str(msg))
return 'foo OK'
def foo1(self, msg):
print('foo1:' + str(msg))
return 'foo1 OK'
opr = OperationsRig()
def operations_module(text):
# Text gives me the name to Match ------------------#
# ------------------------#
# have 3 ways of getting the class instance methods into a list to iterate ..
method_list = [func for func in dir(opr) if callable(getattr(opr, func))]
# This var is a list to pass to the Method
Sel_list = [1,2,3]
# iterate over the "self.OperationsRig" methods
#
""" option 1 """
for meth in method_list:
if text.strip().lower() in meth.lower()[:]:
# if match, and it does, will call the class method and send the data.
pass
return getattr(opr, meth)(Sel_list) # Executes the funcion instance, but is not
# sending the data, I've checked printing inside.
# NoneTypeObject is not iterable. no data sent.
print(operations_module('foo'))
print(operations_module('foo1'))
And this is the result:
foo:[1, 2, 3]
foo OK
foo1:[1, 2, 3]
foo1 OK
Process finished with exit code 0
It runs as my expectation, I still can not figure out why your code is failed. Or if you can give further explanation.
