[英]Adding button (with variables) by pressing button - tkinter
我正在制作一個銷售點系統並嘗試實現一個按鈕,當按下一個新按鈕時,還會出現一個 window,它要求用戶輸入一個項目
def newButton ():
w = Toplevel()
w.title("New Item") #creates new window when button is pressed
w.geometry("200x200")
itemNameLabel = Label(w, font=("arial", 15), text="What is the item called?")
itemNameLabel.grid(row=0, padx=5)
itemName = Entry(w, width=18, borderwidth=5)
itemName.grid(row=1, padx=5)
newItemName = itemName.get
itemPriceLabel = Label(w, font=("arial", 15), text="What is the item's price?")
itemPriceLabel.grid(row=4, padx=5)
itemPrice = Entry(w, width=18, borderwidth=5)
itemPrice.grid(row=5, padx=5)
def item6_Button():
global item6_qty
item6_price = itemPrice.get
item6_text = newItemName
item6_qty += 1
item6_text = (item6_text + " "+str(item6_price) +" "+ str(item6_qty)) #concatonates text & variable
item6.config(text=item6_text) #updates label text - doesn't add multiple
item6.pack()
item6_Button = Button(itemFrame, text=newItemName, width=10, height=5, command=item6_Button)
item6_Button.grid(row=7, column=1, padx=5)
item6 = Label(receiptFrame)
w.mainloop()
newButton= Button(itemFrame, text="Add New Button", width=20, height=5, command=newButton) #creates button for new window
newButton.place(x=480, y=600)
newButton = Label(itemFrame)
*item6_qty 和 item6_price 在程序開頭附近聲明
這是我到目前為止所擁有的,盡管出現了 window,但我認為變量實際上並未設置,位於項目框架中出現的新按鈕之上。 我不完全確定如何 go 關於這個 - 我需要 use.insert 變量嗎?
這是我創建普通按鈕的標准代碼
#Item1 Button + Function
def item1_Button():
global item1_qty #making qty variable global so it can used
item1_text = ("Chips")
item1_qty += 1 #increments qty variable by one everytime button is clicked
item1_text = (item1_text + " "+str(item1_price) +" "+ str(item1_qty)) #concatonates text & variable
item1.config(text=item1_text) #updates label text - doesn't add multiple
item1.pack() #places label within the frame
item1_Button = Button(itemFrame, text="Chips", width=10, height=5, command=item1_Button)
#creates button + links to function
item1_Button.grid(row=4, column=1, padx=5) #positions button
item1 = Label(receiptFrame)#creates label for button
我不確定我是否提供了足夠的代碼來說明我所做的事情,以便更好地了解我正在努力實現的目標,但我知道大塊代碼並不是很受歡迎
這是您可以做什么的示例(這有幫助嗎?):
from tkinter import Tk, Button, Entry, Toplevel
class MainWindow(Tk):
def __init__(self):
Tk.__init__(self)
self.geometry('100x150')
self.btn = Button(self, text='Create New!', command=self.ask)
self.btn.pack()
def ask(self):
ask_window = InputWindow(self)
ask_window.focus_force()
def create(self, text):
button = Button(self, text=text)
button.pack()
class InputWindow(Toplevel):
def __init__(self, parent):
Toplevel.__init__(self, parent)
self.parent = parent
self.bind('<FocusOut>', self.destroy_)
self.user_input = Entry(self)
self.user_input.pack()
self.submit_btn = Button(self, text='Submit!', command=self.retrieve)
self.submit_btn.pack()
def retrieve(self):
text = self.user_input.get()
self.parent.create(text)
self.destroy()
def destroy_(self, event):
if isinstance(event.widget, Toplevel):
self.destroy()
root = MainWindow()
root.mainloop()
