我有2個窗戶。圖形用戶界面和資訊
我想在 GUI 上創建一個按鈕來打開視窗資訊，但我不知道該怎么做。
我嘗試使用 TopLevel 小部件，但我不知道如何正確實作它。
這是GUI的代碼
from tkinter import *
from automata.fa.dfa import DFA
from DFA import arranca
def btn_clicked():
print("Button Clicked")
def submit():
canvas.itemconfig(Canv, text="\t" arranca(entry1.get()))
window = Tk()
window.geometry("880x550")
window.configure(bg = "#ffffff")
canvas = Canvas(
window,
bg = "#ffffff",
height = 550,
width = 880,
bd = 0,
highlightthickness = 0,
relief = "ridge")
canvas.place(x = 0, y = 0)
這是資訊的代碼
from tkinter import *
window = Tk()
window.title("Information")
window.geometry("700x400")
window.configure(bg = "#ffffff")
canvas = Canvas(
window,
bg = "#ffffff",
height = 400,
width = 700,
bd = 0,
highlightthickness = 0,
relief = "ridge")
canvas.place(x = 0, y = 0)
background_img = PhotoImage(file = f"background_1.png")
background = canvas.create_image(
350.0, 188.0,
image=background_img)
window.resizable(False, False)
window.mainloop()
uj5u.com熱心網友回復：
此代碼演示了如何創建Tk帶有按鈕和Toplevel子視窗的視窗。
您所要做的就是使用您喜歡的小部件填充這些視窗。
import tkinter as tk
class GUI:
def __init__(self):
self.parent = tk.Tk()
self.parent.title("GUI Window")
# Button control
button = tk.Button(
self.parent, text = "New window", command = self.window)
button.grid(sticky = tk.NSEW)
# Define window size
self.parent.geometry("278x26")
def window(self):
try:
self.information.winfo_viewable()
except AttributeError as err:
self.information = tk.Toplevel(self.parent)
# Make Toplevel a child of parent
self.information.transient( self.parent )
self.information.title("Information Window")
# place all your widgets here
else:
self.information.focus_force()
if __name__ == "__main__":
app = GUI()
app.parent.mainloop()
