如何獲取tkinter中按鈕的狀態？

from tkinter import *
import time

def checkTime():
    if len(hourInput.get()) != 0 and len(minuteInput.get()) != 0 and len(secondInput.get()) != 0:
        if hourInput.get() == time.strftime("%H"):
            print("good")
    
    window.after(500, checkTime)

def pressButton(button):
        button.config(relief=SUNKEN)

if __name__=='__main__':

    window = Tk()

    window.geometry("1920x1080")

    canvas = Canvas(window, width = 1980, height = 1020)
    
    canvas.pack()

    hourInput = StringVar()
    minuteInput = StringVar()
    secondInput = StringVar()

    setHour = Entry(window, text = hourInput, font = (20))
    setHour.place(x = 100, y = 20, width = 100, height = 40)

    setMinute = Entry(window, text = minuteInput, font = (20))
    setMinute.place(x = 300, y = 20, width = 100, height = 40)


    setSecond = Entry(window, text = secondInput, font = (20))
    setSecond.place(x = 500, y = 20, width = 100, height = 40)
    
    canvas.create_text(60, 40, text = "Hour: ", font = (20))

    canvas.create_text(260, 40, text = "Minute: ", font = (20))

    canvas.create_text(460, 40, text = "Second: ", font = (20))

    submit = Button(text = "Submit", height = 2, width = 10, font = (10))
    submit.config(command = lambda submit=submit:pressButton(submit))

    submit.place(x = 100, y = 100)
    
    checkTime()

    window.mainloop()   

我希望在按下按鈕時呼叫函式 checkTime()。但是如何獲取我的按鈕的狀態并進行比較？我想僅在按下按鈕作為用戶同意其輸入的測驗時才使用該功能

uj5u.com熱心網友回復：

您可以按如下方式修改按鈕宣告，以便在checkTime()按下按鈕時觸發。

submit = Button(text = "Submit", height = 2, width = 10, font = (10), relief=SUNKEN)
submit['command'] = checkTime  # no parentheses here

還要確保洗掉了底部的 checkTime() 方法呼叫

我將函式 checkTime() 放在 pressButton() 函式中，現在程式運行良好。

from tkinter import *
import time

def checkTime():
    if len(hourInput.get()) != 0 and len(minuteInput.get()) != 0 and len(secondInput.get()) != 0:
        if hourInput.get() == time.strftime("%H"):
            print("good")
    window.after(500, checkTime)

def pressButton(button):
        button.config(relief = SUNKEN)
        checkTime()

if __name__== '__main__':

    window = Tk()

    window.geometry("1920x1080")

    canvas = Canvas(window, width = 1980, height = 1020)
    
    canvas.pack()

    hourInput = StringVar()
    minuteInput = StringVar()
    secondInput = StringVar()

    setHour = Entry(window, text = hourInput, font = (20))
    setHour.place(x = 100, y = 20, width = 100, height = 40)

    setMinute = Entry(window, text = minuteInput, font = (20))
    setMinute.place(x = 300, y = 20, width = 100, height = 40)


    setSecond = Entry(window, text = secondInput, font = (20))
    setSecond.place(x = 500, y = 20, width = 100, height = 40)
    
    canvas.create_text(60, 40, text = "Hour: ", font = (20))

    canvas.create_text(260, 40, text = "Minute: ", font = (20))

    canvas.create_text(460, 40, text = "Second: ", font = (20))

    submit = Button(text = "Submit", height = 2, width = 10, font = (10))
    submit.config(command = lambda submit=submit:pressButton(submit))

    submit.place(x = 100, y = 100)

    window.mainloop()
