哈囉大家好想請問一個問題就是我用tk做了兩頁frame(StartPage, ThreePage) 然後我做了兩個按鈕一個從StartPage換到ThreePage 另一個是在StartPage貼一張圖我希望當我按了貼圖的按鈕後再換到ThreePage時圖會消失接著再按home按鈕返回時圖會直接再出現但現在這個寫法是當我按了按鈕以後圖就永遠在那裡換到ThreePage也依舊在那我覺得應該是label那邊不能用root 但我用self他會錯誤想請問該怎麼做呢? 謝謝 import os import sys import matplotlib matplotlib.use("TkAgg") import tkinter as tk import numpy as np import matplotlib.pyplot as plt from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg from matplotlib.figure import Figure from PIL import Image, ImageTk #### Change working dir #### pathProg = os.getcwd() os.chdir(pathProg) def on_Plot(): global img1 global La img1 = ImageTk.PhotoImage(file='Hey.jpg') La = tk.Label(root, text="abc", image=img1, bg='gray') La.place(x=200, y=150, width=100, height=100) La.update_idletasks() class Application(tk.Tk): def __init__(self): super().__init__() self.wm_title('Hello') self.geometry('500x500') container = tk.Frame(self) container.pack(side="top", fill="both", expand = True) container.grid_rowconfigure(0, weight=1) container.grid_columnconfigure(0, weight=1) self.frames = {} for F in (StartPage, PageThree): frame = F(container, self) self.frames[F] = frame frame.grid(row=0, column=0, sticky="nsew") self.show_frame(StartPage) def show_frame(self, cont): frame = self.frames[cont] frame.tkraise() class StartPage(tk.Frame): def __init__(self, parent, root): super().__init__(parent) butt3 = tk.Button(self, text="Page3", command = lambda: root.show_frame(PageThree)) butt3.place(x=100, y=400, width=150, height=80) butt4 = tk.Button(self, text="Plot", command = on_Plot) butt4.place(x=300, y=400, width=150, height=80) class PageThree(tk.Frame): def __init__(self, parent, root): super().__init__(parent) button1 = tk.Button(self, text="Home", command=lambda: root.show_frame(StartPage)).pack() root = Application() root.mainloop() -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 123.195.194.74 ※ 文章網址: https://www.ptt.cc/bbs/Python/M.1536933748.A.BBE.html
