    <p>Suppose I have this class:</p> <pre><code>class MyClass(object): def uiFunc(self, MainWindow): self.attr1 = "foo" self.attr2 = "bar" def test(): from subclassfile import MySubClass MySubClass.firstFunc(self, 2, 2) test() </code></pre> <p>And this subclass in other file:</p> <pre><code>from classfile import MyClass class MySubclass(MyClass): def firstFunc(self, a, b): c = a + b d = self.secondFunc(self, c) return d def secondFunc(self, c): d = c / 2 return d </code></pre> <p>This is a silly example, but represents exactly what I'm trying to do. I want to call the second function from the subclass inside the first function. But when I do that it returns an error that says that MyClass doesn't have such function. So I suppose that I shouldn't be using the <code>self</code> in front of the function name when I call it. But when I don't it raises an error too.</p> <p>So my question is: How do I access this second function inside the first function of a subclass?</p> <p>EDIT:</p> <p>Thank you all for the help. I'll explain better what I'm trying to do while I guess that my implementation is really bad in the code. MyClass is the main Class of the code, where all the widgets and main functions are. There is also a button on this Class that is binded with the "test" function. So when the button is pressed the whole thing should work. The MySubClass file is an auxiliary module that exports data to some file. The firstFunc is the main function in this module that handles with all the data while secondFunc just builds the template of the file. So I call this secondFunc inside the firstFunc so that the template is loaded and then the data is written in the file. I made this MySubClass inherited from the MyClass so that it could have access to the database and other variables directly from the MyClass.</p> <p>So I suppose that I could do this otherway. But I'm not really experienced with this kind of implementation. Also, sorry for my bad english.</p>

    1. CO"This is a silly example, but represents exactly what I'm trying to do" But why do you want to call a method from the subclass in a superclass method? This makes no sense...

    2. CO*Why* do you want to do it? As you have described it, you *really* shouldn't do it. Really *really* shouldn't. Please describe what you want to achieve. There is almost certainly a correct way to achieve it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
