我正在使用 tkinter 創建多個視窗 GUI。我沒有收到任何錯誤。第一個視窗運行成功，但是當我單擊按鈕時，第二個視窗沒有運行。
我不明白哪里有錯誤，如果我打包Entry小部件和Buttons 它們不會顯示在視窗中。
import tkinter as tk
import pywhatkit
import pyautogui
class automation(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.geometry("842x510")
self.configure(bg="#ffffff")
self.resizable(False, False)
self.container = container = tk.Frame(self, background="#ffffff")
container.grid(row=0, column=0, sticky='nesw')
container.configure(background="#ffffff")
container.pack(side="top", fill="both")
self.frames = {}
for F in (MainWindow, SecondWindow):
page_name = F.__name__
frame = F(parent=container, controller=self)
frame.grid(row=0, column=0, sticky="nsew")
self.frames[page_name] = frame
self.show_frame('MainWindow')
def show_frame(self, page_name):
if page_name not in self.frames:
self.frames[page_name] = page_name(self.container, self)
frame = self.frames[page_name]
frame.tkraise()
def btn_clicked():
print("Button Clicked")
第一個視窗的代碼。
class MainWindow(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
self.frame = tk.Frame(self, background="#ffffff")
self.canvas = tk.Canvas(self, bg="#ffffff", height=510, width=391, bd=0,
highlightthickness=0, relief="ridge")
self.canvas.place(x=0, y=0)
self.canvas.pack(side='left')
self.background_img = tk.PhotoImage(file="background.png")
self.canvas.create_image(0, 0, image=self.background_img, anchor="nw")
self.img1 = tk.PhotoImage(file="img1.png")
self.b1 = tk.Button(self, image=self.img1, borderwidth=0, highlightthickness=0,
command=lambda: controller.show_frame(SecondWindow),
relief="flat")
self.b1.place(x=392, y=100, width=348, height=62)
self.b1.pack(padx=10, pady=125)
self.b1.pack()
# creating third button
self.img3 = tk.PhotoImage(file="img3.png")
self.b3 = tk.Button(self, image=self.img3, borderwidth=0, highlightthickness=0,
command=btn_clicked, relief="flat")
self.b3.place(x=392, y=200, width=348, height=62)
self.b3.pack(padx=10, pady=0)
self.b3.pack()
self.canvas.pack()
def send(num, msg, hour, minute):
pywhatkit.sendwhatmsg(f" 91{num}", msg, hour, minute, 36)
print("hello")
pyautogui.click()
pyautogui.press("enter")
第二個視窗的代碼：
class SecondWindow(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
a = tk.StringVar()
b = tk.StringVar()
c = tk.IntVar()
d = tk.IntVar()
self.controller = controller
self.frame = tk.Frame(self, background="#ffffff")
self.canvas = tk.Canvas(self, bg="#ffffff", height=510, width=842, bd=0,
highlightthickness=0, relief="ridge")
self.canvas.place(x=0, y=0)
self.canvas.pack(side='left')
# set image in background
self.background_img = tk.PhotoImage(file="background2.png")
self.canvas.create_image(0, 0, image=self.background_img, anchor="nw")
# enter a number
self.entry1_img = tk.PhotoImage(file="textBox1.png")
self.canvas.create_image(570, 112, image=self.entry1_img)
self.entry1 = tk.Entry(self, bd=0, bg="#c4c4c4", highlightthickness=0, textvariable=a)
self.entry1.place(x=423, y=90, width=280, height=45)
#self.entry1.pack()
# enter a massage
self.entry2_img = tk.PhotoImage(file="textBox2.png")
self.canvas.create_image(570, 225, image=self.entry2_img)
self.entry2 = tk.Entry(self, bd=0, bg="#c4c4c4", highlightthickness=0, textvariable=b)
self.entry2.place(x=423, y=203, width=280, height=45)
#self.entry2.pack()
# enter a time -> Hour
self.entry3_img = tk.PhotoImage(file="textBox3.png")
self.canvas.create_image(470, 329, image=self.entry3_img)
self.entry3 = tk.Entry(self, bd=0, bg="#c4c4c4", highlightthickness=0, textvariable=c)
self.entry3.place(x=423, y=312, width=80.0, height=35)
#self.entry3.pack()
# minute
self.entry4_img = tk.PhotoImage(file="textBox4.png")
self.canvas.create_image(676, 329, image=self.entry4_img)
self.entry4 = tk.Entry(self, bd=0, bg="#c4c4c4", highlightthickness=0, textvariable=d)
self.entry4.place(x=630, y=312, width=80.0, height=35)
#self.entry4.pack()
# Go home
self.img4 = tk.PhotoImage(file="img4.png")
self.b4 = tk.Button(self, image=self.img4, borderwidth=0, highlightthickness=0,
command=lambda: controller.show_frame(MainWindow), relief="flat")
self.b4.place(x=418, y=400, width=100, height=37)
#self.b4.pack()
# Send message
self.img5 = tk.PhotoImage(file="img5.png")
self.b5 = tk.Button(self, image=self.img5, borderwidth=0, highlightthickness=0,
command=lambda: send(a.get(), b.get(), c.get(), d.get()),
relief="flat")
self.b5.place(x=642, y=400, width=100, height=37)
#self.b5.pack()
self.canvas.pack()
if __name__ == '__main__':
app = automation()
app.mainloop()
uj5u.com熱心網友回復：
command=lambda: controller.show_frame(SecondWindow),正在將類 ID 作為引數傳遞，因此page_name找不到。
建議
command=lambda: controller.show_frame('SecondWindow')
