Hi Guys,
I need your help
This Stuff is working well:
import tkinter as tk
from tkinter import *
from tkinter import ttk, filedialog
## window
win = Tk() # Create an instance of tkinter frame
win.title(' F04 universal GUI ') #set title of window
myscreenwidth= win.winfo_screenwidth() #get screenwidth
myscreenheight= win.winfo_screenheight() #get screenheight
win.geometry("%dx%d+0+0" %(myscreenwidth,myscreenheight)) #set window size to full screen[b][/b]But now i want to create a new class for my frames ( -> same attributes (like background color) for all instances), which does not really work:
#define a notebook
notebook1=ttk.Notebook(win) #initialise
notebook1.pack(fill="both", expand=1) #most simple placement for only 1 object
class CustomFrames(tk.Frame):
def __init__(self,notebook1):
super().__init__(notebook1)
super().notebook1.add(self.frame, text="Start ")
frame01Start=CustomFrames(notebook1) #create instanceError:
super().notebook1.add(self.frame, text="Start ")
AttributeError: 'super' object has no attribute 'notebook1'
Any ideas whats wrong here?
I also found out that this (below) works well, but i find it not an elegant style to create an object "Frame01.frame" , and also I would like to understand the issue about my original code...
class CustomFrames:
def __init__(self):
self.frame=tk.Frame(notebook1)Thank you for your help!
Finally I found a solution:
class CustomFrames(tk.Frame):
def __init__(self,parent):
super().__init__(parent)
#self.parent.add(self.frame, text="Start ")
notebook1.add(self, text="Start ") # add a tab to the notebook
frame01Start=CustomFrames(notebook1)
Just a small change to make a much better better solution:
class CustomFrames(tk.Frame):
def __init__(self, parent, name, *args, **kwargs):
super().__init__(parent, *args, **kwargs)
parent.add(self, text=name)
frame01Start=CustomFrames(notebook1, "Start")Your frame class should not have to know about frame01Start and the tab name should not be limited to "Start". These should be passed as arguments to the __init__() method.
*args and **kwargs allow passing additional arguments to Frame.__init__(). CustomFrames doesn't have to know anything about these arguments, it just passes them along to the Frame.__init__() method.

Just a small change to make a much better better solution:
[python]class CustomFrames(tk.Frame):
def __init__(self, parent, name, *args, **kwargs):
super().__init__(parent, *args, **kwargs)
parent.add(self, text=name)
I don't understand the "Correction". It looks like *args and **kwargs are crossed out.
You want to pass *args and **kwargs as arguments to super().__init__(). This lets you pass arguments that are understood by Frame.
In this example I use **kwargs to set the background color for the frame. I also show you you can subclass classes that you make, not just tkinter classes. I wrote a custom class for each page I add to the notebook.
import tkinter as tk
import tkinter.ttk as ttk
class NotebookPage(tk.Frame):
def __init__(self, parent, name, *args, **kwargs):
super().__init__(parent, *args, **kwargs)
parent.add(self, text=name)
class Page1(NotebookPage):
def __init__(self, parent, *args, **kwargs):
super().__init__(parent, "Page 1", *args, **kwargs)
tk.Label(self, text="This is page 1", bg=self["bg"]).pack(padx=10, pady=10)
class Page2(NotebookPage):
def __init__(self, parent, *args, **kwargs):
super().__init__(parent, "Page 2", *args, **kwargs)
tk.Label(self, text="This is page 2", bg=self["bg"]).pack(padx=10, pady=10)
class MyWindow(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
notebook = ttk.Notebook(self)
notebook.pack(padx=5, pady=5)
Page1(notebook, bg="yellow")
Page2(notebook, bg="light blue")
MyWindow().mainloop()
