Tkinter：從主窗口獲取信息到新的 window

Question

我正在使用 Tkinter，我將從用戶那里獲取數據並將它們顯示在新的 window 中。但是我正在努力在新的 window 中顯示信息。我嘗試使用 the.get() 並只是打印但是新的 window 打開時沒有數據。

我試過使用 messageBox 但它似乎也不是我想要發生的事情。

這是代碼

from tkinter import *


class peronalInfo_GUI():
    def __init__(self):
        #create window and set title
        self.mainWindow = Tk()
        self.mainWindow.title("Property Taxes)")
        window_width = 330
        window_height = 150
        
        # get the screen dimension
        screen_width = self.mainWindow.winfo_screenwidth()
        screen_height = self.mainWindow.winfo_screenheight()
        # find the center point
        center_x = int(screen_width/2 - window_width / 2)
        center_y = int(screen_height/2 - window_height / 2)
        # set the position of the window to the center of the screen
        self.mainWindow.geometry(f'{window_width}x{window_height}+{center_x}+{center_y}')
        #self.mainWindow.geometry("250x160")
        
        #Label 1 --> User Input name
        self.nameLabel = Label(self.mainWindow, text = "Enter your name: ")
        self.nameTextBox = Entry(self.mainWindow, width = 25)
        self.nameLabel.grid(row = 0, column = 0)
        self.nameTextBox.grid(row = 0, column = 1)
        
        #Label 2 --> User Input address
        self.addressLabel = Label(self.mainWindow, text = "Enter address: ")
        self.addressTextBox = Entry(self.mainWindow, width = 25)
        self.addressLabel.grid(row = 1, column = 0)
        self.addressTextBox.grid(row = 1, column = 1)
        
        #Label 3 --> User Input phone number
        self.phoneNumberLabel = Label(self.mainWindow, text = "Enter phone number: ")
        self.phoneNumberTextBox = Entry(self.mainWindow, width = 25)
        self.phoneNumberLabel.grid(row = 2, column = 0)
        self.phoneNumberTextBox.grid(row = 2, column = 1)
        
        #Label 4 --> User input college major
        self.collegeMajorLabel = Label(self.mainWindow, text = "Enter your college major: ")
        self.collegeMajorTextBox = Entry(self.mainWindow, width = 25)
        self.collegeMajorLabel.grid(row = 3, column = 0)
        self.collegeMajorTextBox.grid(row = 3, column=1)
        
        #Create Buttons for event handling
        self.displayInfo = Button(self.mainWindow, text = "Display Information", bg = "#BB8FCE", command = self.openNewWindow)
        self.exitButton = Button(self.mainWindow, text = "Exit", bg = "#F1948A", command = self.mainWindow.destroy)
        self.displayInfo.grid( row = 5, column = 0, padx = 15, pady = 15)
        self.exitButton.grid ( row = 5, column=  1)
        #Loop
        self.mainWindow.mainloop()
        
    def openNewWindow(self):
        newWindow = Toplevel(self.mainWindow)
        newWindow.title("Display Info")
        newWindow.geometry("350x150")

        #Display User Info
        self.displayName = Label(text = self.nameTextBox.get(), row = 1)
        self.displayAddress = Label(text = self.addressTextBox.get(), row = 2)
        self.displayNumber = Label(text = self.phoneNumberTextBox.get(), row = 3)
        self.displayMajor = Label(text = self.collegeMajorTextBox.get(), row = 4)
            
            
def main():
    callGUI = peronalInfo_GUI()

main()

Answer 1

您似乎沒有在控制台中運行代碼，因為您會看到錯誤

_tkinter.TclError: unknown option "-row"

這可以部分解決問題

我看到兩個問題：

第一的：

你用

var = Label(..., row=1)

但它必須是

var = Label(...)
var.grid(row=1)

這會產生錯誤。

第二：

您創建Label而沒有parent項作為第一個值 - 因此它將使用mainWindow作為parent項並且它將在第一個 window 而不是新的 window 中顯示Label 。

你需要：

Label(newWindow, ...)

    def openNewWindow(self):
        newWindow = Toplevel(self.mainWindow)
        newWindow.title("Display Info")
        newWindow.geometry("350x150")

        #Display User Info
        self.displayName = Label(newWindow, text=self.nameTextBox.get())
        self.displayName.grid(row=1)
        
        self.displayAddress = Label(newWindow, text=self.addressTextBox.get())
        self.displayAddress.grid(row=2)
        
        self.displayNumber = Label(newWindow, text=self.phoneNumberTextBox.get())
        self.displayNumber.grid(row=3)
        
        self.displayMajor = Label(newWindow, text=self.collegeMajorTextBox.get())
        self.displayMajor.grid(row=4)
