Access from one class to methode of other class

[VK]

Hi, all!

In my programm i have to insert a variable from class 2 to class 1 and I 
get error NameError: global name 'd' is not defined. How do I get access 
to d.entry.insert() method of class 1

class 1:
self.entry = Entry(self.entryframe)
self.entry.pack()

self.button = Button(command = self.callclass2window)

def callclass2window
c = 2()


class 2:
def ins(self)
d.entry.insert(variable)


d = 1()

What is d = 1() in my example then? And how do I solve this problem?

That is not real code, only dummy describing the problem

That insert text into entry object.

I try:

from Tkinter import *

class First:
 def __init__(self):
 self.root = Tk()  # create window contents as children to 
root..
 self.entryframe = Frame(self.root)
 self.entryframe.pack(fill=BOTH,expand=1)

 self.entry = Entry(self.entryframe)
 self.entry.pack(side=TOP,expand=1,fill=BOTH)
 self.entry.focus()
 self.entry.bind('',(lambda event: self.fetch())) # 
on enter key

 self.button = 
Button(self.entryframe,text="Call",command=self.getvar)
 self.button.pack(side=LEFT,expand=YES,fill=BOTH)

 self.root.mainloop()

 def fetch(self):
 print 'Input => "%s"' % self.entry.get() # get text form entry

 def getvar(self,event=0):
 c=Second(self,self.root)



class Second:
 def __init__(self,parent,s="thing"):
 self.root = Tk()
 self.ent = Entry(self.root)
 self.ent.pack()
 self.btn = Button(self.root,text='Fetch',command=self.fetch)
 self.btn.pack(side=RIGHT)
 def fetch(self):
 text = self.ent.get() # get text form entry in this window
 d.entry.insert(0, text)# must insert in other window

d = First() #First window

O, God! It works! Thousend of thanks!

By the way, the second window appears not activ, is there an option to

Getting value of radiobutton trouble

[VK]

Hi!
What I'm missing in following code? Cannot get the values of 
radiobuttons. Starting only one class (GetVariant), it works. When I put 
two classes together, it doesn't.
Regards, VK

from Tkinter import *
class GetVariant:
 def __init__(self):
 self.root = Tk()
 self.mainframe = Frame(self.root,bg="yellow")
 self.mainframe.pack(fill=BOTH,expand=1)

 self.firstframe = Frame(self.mainframe,bg="red")
 self.firstframe.pack(side=BOTTOM,expand=1)

 global v
 v = StringVar()
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
1", variable=v, value="Variant 1")
 self.radiobutton.pack(side=TOP,anchor=W)
 self.radiobutton.select()
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
2", variable=v, value="Variant 2")
 self.radiobutton.pack(side=TOP,anchor=W)
 self.radiobutton = Radiobutton(self.firstframe,text= "Variant 
3", variable=v, value="Variant 3")
 self.radiobutton.pack(side=TOP,anchor=W)



 self.secondframe = Frame(self.mainframe,bg="blue")
 self.secondframe.pack()
 self.var = Button(self.secondframe,text="What 
Variant",command=self.call)
 self.var.pack(expand=1,side=BOTTOM)



 def call(self):
 self.variant = v.get()
 print 'Input => "%s"' % self.variant

class OneButton:
 def __init__(self):
 self.root = Tk()
 Button(self.root,text="click me",command=self.getvar).pack()
 def getvar(self):
 a=GetVariant()

d = OneButton()
d.root.mainloop()

Sorry, but I don't get it. There is no deference between my code and 
your answer. I'm beginner...

So, your code works, but I need, that first window calls another

Linux, Windows. TkInter, Pmw.
I've already implemented this with code under my message, but "cut"
copies entrytext, without deleting selection. Any ideas

def copy(self):
 global copied
 if self.entry.selection_present():
self.entry.clipboard_clear()
copied = self.entry.selection_get()
 self.entry.bell()
 def paste(self):
 self.entry.insert(END, copied)

 self.entry.clipboard_clear()

 copied = self.entry.selection_get()
 self.entry.selection_clear()

Entry scroll doesn't work

[VK]

Hi!
Can entry widget be scrolled?
VK

TypeError: xview() takes exactly 2 arguments (4 given)

Code:



from Tkinter import *
class ScrollEntry:
 def __init__(self):
 self.root = Tk()
 self.scrollbar = Scrollbar(self.root,orient=HORIZONTAL,)
 self.entry = Entry(self.root,xscrollcommand=self.scrollbar.set)
 self.entry.focus()
 self.entry.pack(side=TOP,fill=X)
 self.scrollbar.pack(fill=X)
 self.scrollbar.config(command=self.entry.xview)
 self.entry.config()


a=ScrollEntry()
a.root.mainloop()

Their *JScript* documentation website - here's the keyword.

 See:


After the official breakup with IE for Mac OS:


JScript site is now only and exclusively for Internet Explorer 5.5 and
higher under Windows 98 SE and higher.

Any other visitors are out of support and interest of Microsoft - at
least in JScript domain. It is bad and rude, but it is and I'm affraid
it will be.

for built-in you don't need *self*

If you define yours, try

def quit(self,event=0)
