So fügen Sie Optionsmenüs hinzu, wenn Sie einen Datensatz in tkinter erstellen

Question

Hallo ich bin ganz neu in Tkinter und dieser Seite.

In tkinter möchte ich in der Lage sein, ein Optionsmenü hinzuzufügen, das die Liste der Elemente und Lieferanten zeigt, die ein Benutzer wählen kann, um eine Bestellung zu machen, aber ich habe keine Ahnung, wie Sie das Optionsmenü erhalten (bei Bedarf zur Verfügung stellen kann ich andere Daten)

# Frame 5 - Add Order - window that allows the user to make an order using several entry widgets 
    def create_Order_Var(): 
     f5.tkraise() 
     # Data headings 
     Label(f5, text="Date 'dd/mm/yy'",bg="#E5E5E5", anchor="w").grid(row=1, column=0, sticky=E+W) 
     Label(f5, text="Price",bg="#E5E5E5", anchor="w").grid(row=2, column=0, sticky=E+W) 
     Label(f5, text="Quantity",bg="#E5E5E5", anchor="w").grid(row=3, column=0, sticky=E+W) 
     Label(f5, text="Item ID",bg="#E5E5E5", anchor="w").grid(row=4, column=0, sticky=E+W) 
     Label(f5, text="Supplier ID",bg="#E5E5E5", anchor="w").grid(row=5, column=0, sticky=E+W) 

     # Setting variables to approriate types 
     newDate = StringVar() 
     newPrice = DoubleVar() 
     newQuantity = DoubleVar() 
     newItemID = IntVar() 
     newSupplierID = IntVar() 

     #Item Option Menu 
     variable = StringVar(f5) 
     variable.set("Select Item") # default value 

     items = get_all_inventory() 
     items_formatted = [] 
     for item in items: 
      items_formatted.append(item[0]) 
     print(items_formatted) 
     # Establishing option menu widget 
     optionbox = OptionMenu(f5, variable, *items_formatted) 

     #Supplier Option Menu 
     variable2 = StringVar(f5) 
     variable2.set("Select Supplier") # default value 

     suppliers = get_all_suppliers() 
     suppliers_formatted = [] 
     for supplier in suppliers: 
      suppliers_formatted.append(supplier[0]) 
     print(suppliers_formatted) 
     # Establishing option menu widget 
     optionbox2 = OptionMenu(f5, variable2, *suppliers_formatted) 

     # Establishing entry widgets 
     entry_Date = Entry(f5,textvariable=newDate).grid(row=1,column=1) 
     entry_Price = Entry(f5,textvariable=newPrice).grid(row=2,column=1) 
     entry_Quantity = Entry(f5,textvariable=newQuantity).grid(row=3,column=1) 
     entry_ItemID = optionbox.grid(row=4,column=1) 
     entry_SupplierID = optionbox2.grid(row=5,column=1) 

     def add_Order():    

      try: 
       date = newDate.get() 
       price = newPrice.get() 
       quantity = newQuantity.get() 
       itemID = newItemID.get() 
       supplierID = newSupplierID.get()      
       # Stops invalid data by disallowing fields with the wrong data type 
       float(price) 
       int(quantity) 
       int(itemID) 
       int(supplierID) 
       # Calling of create order query 
       create_order(date,price,quantity,itemID,supplierID) 
       print("You have added: {0},{1},{2},{3},{4}".format(date,price,quantity,itemID,supplierID)) 
       # After an order has been place the window switches to the check order frame for the user to check that their order was made 
       check_Order() 
      except: 
       # Error message when invalid data is entered 
       print("Invalid Data. Price must be a number above zero. Quantity must be an integer above zero") 

     Button(f5,text = "Create Order",command = add_Order).grid(row = 6, column = 2, padx = 10) 

Answer 1

Sie Option ausgewählt hat, in variable.get() und jetzt müssen Sie es verwenden, um: mit dem Datum Preis und Menge

Hier ist mein Code so weit für diesen Rahmen finden Sie weitere Informationen in items Liste. Es könnte einfacher sein, wenn Sie ein Wörterbuch anstelle einer Liste hätten.

Beispiel mit Liste

#!/usr/bin/env python3 

import tkinter as tk 

# --- functions --- 

def on_button(): 

    # - list - 

    # selected option 
    sel_list = select_list.get() 
    print('list - key:', sel_list) 

    # find on list 
    keys_list = [x[0] for x in items_list] 

    if sel_list in keys_list: 
     idx = keys_list.index(sel_list) 
     item_list = items_list[idx] 
    else: 
     item_list = None 

    print('list - item:', item_list) 

    print('---') 

# --- data --- 

# - list - 

# list with items 
items_list = [ 
    ['Item A', 'Today', 'Hello'], 
    ['Item B', 'Tomorrow', 'World'] 
] 

# --- main --- 

root = tk.Tk() 

# - list - 

# variable for selected item 
select_list = tk.StringVar() 
select_list.set("Select Item") 

# use list first column as options 
keys_list = [x[0] for x in items_list] 

op_list = tk.OptionMenu(root, select_list, *keys_list) 
op_list.pack() 

# - 

b = tk.Button(root, text='OK', command=on_button) 
b.pack() 

root.mainloop() 

Beispiel mit Wörterbuch

#!/usr/bin/env python3 

import tkinter as tk 

# --- functions --- 

def on_button(): 

    # - dictionary - 

    # selected option 
    sel_dict = select_dict.get() 
    print('dict - key:', sel_dict) 

    # find in dictionary 
    if sel_dict in items_dict: 
     item_dict = items_dict[sel_dict] 
    else: 
     item_dict = None 

    print('dict - item:', item_dict) 

    print('---') 

# --- data --- 

# - dictionary - 

# dictionary with items 
items_dict = { 
    'Item A': ['Today', 'Hello'], 
    'Item B': ['Tomorrow', 'World'] 
} 

# --- main --- 

root = tk.Tk() 

# - dictionary - 

# variable for selected item 
select_dict = tk.StringVar() 
select_dict.set("Select Item") 

# use dictionary keys as options 
# (dictionary doesn't have to keep order so I sort it) 
keys_dict = sorted(items_dict) 

op_dict = tk.OptionMenu(root, select_dict, *keys_dict) 
op_dict.pack() 

# - 

b = tk.Button(root, text='OK', command=on_button) 
b.pack() 

root.mainloop()
