[英]Displaying an image in only its own frame with tkinter
我正在嘗試使用帶有按鈕和圖像的tkinter創建一個簡單的GUI。 我有一個帶有圖像和按鈕的首頁,可以將您帶到其他頁面(框架)。 問題是我的起始頁中的圖像仍然存在並顯示在其他框架中。
編碼:
import tkinter as tk
LARGE_FONT = ("Verdana", 12)
class SeaofBTCapp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
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, PageOne, PageTwo):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.geometry("800x480")
self.show_frame(StartPage)
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="Start Page", font=LARGE_FONT)
label.pack(pady=10, padx=10)
#canvas1 = tk.Canvas(width=600, height=300, bg="gray")
#self.img = tk.PhotoImage(file="mario.png")
#canvas1.create_image(20, 20, image=self.img)
#canvas1.pack()
photo = tk.PhotoImage(file="mario.png")
labelimg = tk.Label(image=photo)
labelimg.image = photo # keep a reference!
labelimg.pack()
button = tk.Button(self, text="Visit Page 1",
command=lambda: controller.show_frame(PageOne))
button.pack()
button2 = tk.Button(self, text="Visit Page 2",
command=lambda: controller.show_frame(PageTwo))
button2.pack()
class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="Page One!!!", font=LARGE_FONT)
label.pack(pady=10, padx=10)
button1 = tk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(StartPage))
button1.pack()
class PageTwo(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="Page Two!!!", font=LARGE_FONT)
label.pack(pady=10, padx=10)
button1 = tk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(StartPage))
button1.pack()
button2 = tk.Button(self, text="Page One",
command=lambda: controller.show_frame(PageOne))
button2.pack()
app = SeaofBTCapp()
app.mainloop()
問題是您尚未指定labelimg
的父級,因此默認情況下它是主窗口。 因此,標簽被包裝在容器下方,因此始終可見。
更改
labelimg = tk.Label(image=photo)
成
labelimg = tk.Label(self, image=photo)
在類StartPage
應該可以解決您的問題。
