I just started programming.
You can display windows and combo boxes, but when you select items in the combo box, you get an error.
Below is the bit device type acquisition part.
I've tried many things, but it doesn't work.Thank you for your cooperation.
import tkinter ask
import tkinter.ttk as ttk
import sys
from tkinter.filedialog import askopenfilename
from tkinter import*
class mainwindow(tk.Frame):
def__init__(self, master=None):
super().__init__(master)
self.master.title("TEST")# Window Title Settings
self.master.geometry("600x600")# window size setting
self.pack()#Mainframe Placement
self.create_menu()#Generate Menu
# Generating a Menu
def create_menu(self):
# open a configuration window
def winsetting():
settingwin=Toplevel(self)
settingwin.title ("SUB")
settingwin.geometry("300x300")
# Set to modal (until this window closes, no other window operations are allowed)
settingwin.grab_set()
# arrangement of parts
label_bittype=tk.Label(settingwin, text="bit device Type")
label_bittytype.place(x=5,y=70)
# Bit Device Type
bit_type=ttk.Combobox(settingwin, values=("A", "B", "C", "D", "E"), state="readonly")
bit_type.bind("<<ComboboxSelected>>", get_bititem)
bit_type.place(x=100,y=70)
# Get Bit Device Type <----------------------------------------------------------------
def get_bititem(self, event):
print(bit_type.get())
self.menubar=tk.Menu(self)#Generate a menubar instance from the Menu class
root.config(menu=self.menubar)# Menu Bar Placement
self.setting_menu=tk.Menu(self.menubar,tearoff=0)#Generate large item "Settings" in menu bar
self.menubar.add_cascade(label="settings", menu=self.setting_menu)# Install the big item "settings"
self.setting_menu.add_command(label="settings", command=winsetting)# Assign subitem "settings"

app.mainloop()
First of all, there are two types of fixes, and the ones I commented on in ### are the fixes.
I can't say which is better, and there may be a better way.
In any case, it would be better to clarify where variables and functions/methods are defined/affiliated, and where they can be accessed.
Note: Simplettk ComboBox demo
def get_bititem(self,event):Move from def create_menu(self): to class mainwindow(tk.Frame):.bit_type.bind("<<ComboboxSelected>>",get_bititem) does not have enough self. for callback routine specification.def winsetting(): or def get_bititem(self, event): bit_type is missing before bit_type.Change to self.bit_type respectively.import tkinter ask

Note: Tkinter Tutorial - Combo Box Combo Box
defget_bititem(self,event): self, is unnecessary. event is the best defget_bititem(event):
Define def create_menu(self):, not in def create_menu(self): but in def winsetting(): bit_type.bind("<<ComboboxSelected>">>>>>>bitem> before .
