python 2.7 - Tkinter callback in a class -


I understand the concept callback button in the function and process. How can this code be implemented in class? I have a problem about the callback button in the tanker, to get value from the class. I can not use the callback method Erode program = Callback not defined. Tycanetter import * class program: def __init __ (self): self.root = Tk) self.root.title ("sample") self.display = entry (self.root) Self.display.grid (line = 1, column = 0, column = 5) button (self.root, text = "Proces" (width = 5, foreground = "blue", command = callback) .Grid (line = 4 , Column = 0) def callback (self): print hello program = programmable () menopause ()

What you need to do is use it: instead of command = self.callback command = callback

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
