Python classes keep calling eachother


Python classes keep calling eachother

To fix the issue you can do
The GuiStart class starts the tkinter gui. The window with buttons and entries is created with that class. From the GuiStart class I call methods that do things like copy files to a certain location
code :
class DecToolsClass:
    def __init__(self):
        self.gui = gui.GuiStart()
def main():
    tools = DecToolsClass()  # not shown, but it no longer has self.gui

    root = tkinter.Tk()
    my_gui = gui.GuiStart(root, tools)
    root.mainloop()

if __name__ == '__main__':
    main()
class GuiStart:    
    def __init__(self, master, tools):
        self.master = master
        self.master.title("DECTools 1.3")
        self.tools = tools

will help you I'm writing a app in NetBeans. I have two classes MyApp_View and MyApp_Functions. ,
MyApp_View my_view = new MyApp_View(null);
code :
class A {
    private B b;

    public A() {
        this.b = new B(this);
    }
}

class B {
    private A a;

    public B(A a) {
        this.a = a;
    }
}

This might help you I have two classes: , You could either make one class instantiate the other:
code :
class A(object):
  def __init__(self):
    self.b = B(self)

class B(object):
  def __init__(self, a):
    self.a = a

a = A()
b = a.b
class A(object):
  def __init__(self, b):
    self.b = b
    b.a = self

class B(object):
  def __init__(self):
    #Will be set by A later
    self.a = None

b = B()
a = A(b)

Hope that helps I have two classes, lets say Class A and Class B. My goal is to have both classes use eachothers functions. Problem is, the multi-file include structure doesn't seem to let me do that. Here's what I'm trying to do: , Maybe using forward declarations?
code :
#file A.h

#ifndef ACLASS_H
#define ACLASS_H

Class B;

Class A{
public:
    int GetInfo();

private:
    B * ptrToB;
};

#endif
#file A.cpp

#include "B.h"

A::A() : ptrToB(0)
{
  // Somehow get B
}

int A::GetInfo() 
{
  // Return whatever you need in here.
}
// Would need the header because we must know 
// the size of B at compile time.
class B;
class A 
{
  B theB; 
}


// Only need forward declaration because a 
// pointers size is always known by the compiler
class B;
class A
{
  B * bPointer; 
}

may help you . Here's a suggestion that will break the cycle: Specify one class as the parent and the other as the dependent.
Let's put Alpha in charge:
code :
public class Alpha {

   private Beta beta;

   public Alpha() {
       this.beta = new Beta(this);
   }
}
public class Beta {

   private Alpha alpha;

   public Beta(Alpha parent) {
       this.alpha = parent;
   }
}

I wish this helpful for you I'm not sure if I'm stating the obvious here, but you need a public accessor for your Rectangle in your Battleship class. If you don't understand what that means then you need to do some reading on the basics of object-oriented programming. For now, though, if you modify the code of your Battleship class to say
