Ronald :
I'm trying to get the value of WxPython checkboxes. When I run the following command inside my Class:
print(self)
a = dir(self)
print(a)
#result
<__main__.Window object at 0x03B02670>
['AcceleratorTable', 'AcceptsFocus', etc...
'm_staticText3', 'm_staticText31', 'm_staticText311', 'm_staticText3111', 'm_staticText3112', 'm_staticText31121', 'm_staticline1', 'm_staticline3']
My checkboxes are part of the returned result. But when I substitute the 'self' for the class 'Window', the checkbox attributes are missing!
print(Window)
a = dir(Window)
print(a)
#result
<class '__main__.Window'>
['AcceleratorTable', 'AcceptsFocus', etc..,
'WindowVariant', '__bool__', '__class__', '__del__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__nonzero__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__']
It looks the same, but my checkboxes are not returned! What's going on here?
chuck2002 :
A class such as Window
is not instantiated. Therefore it can't access anything that requires a class instance. In the following code:
class A:
b = 0
def __init__(self):
self.a = 1
print(dir(A))
inst = A()
print(dir(inst))
dir(A)
will not contain a
, because access to a
requires instantiation as it is declared individually for each instance in the __init__
method. It will contain b
, which is static (belongs to the class itself and not its instances). dir(inst)
will contain both a
and b
.
