Python Tkinter iconphoto()用法及代碼示例

iconphoto()方法用於設置任何tkinter /頂層窗口的標題欄圖標。但是要將任何圖像設置為標題欄的圖標，圖像應該是PhotoImage類的對象。

用法:

iconphoto(self, default = False, *args)

設置圖標圖像的步驟-

from tkinter import Tk
master = Tk()

photo = PhotoImage(file = "Any image file")
master.iconphoto(False, photo)

根據通過的命名照片圖像為此窗口設置標題欄圖標args。如果default為True，這也將應用於將來創建的所有頂級。圖像中的數據在調用時作為快照。如果以後更改圖像，則不會在標題欄圖標中反映出來。該函數還可以將提供的圖標縮放到適當的大小。

代碼1：提供PhotoImage時。

# Importing Tkinter module 
from tkinter import * from tkinter.ttk import *
  
# Creating master Tkinter window 
master = Tk() 
  
# Creating object of photoimage class 
# Image should be in the same folder 
# in which script is saved 
p1 = PhotoImage(file = 'info.png') 
  
# Setting icon of master window 
master.iconphoto(False, 'info.png') 
  
# Creating button 
b = Button(master, text = 'Click me !') 
b.pack(side = TOP) 
  
# Infinite loop can be terminated by 
# keyboard or mouse interrupt 
# or by any predefined function (destroy()) 
mainloop()

輸出：

異常：如果直接提供圖像而不是PhotoImage對象，則它將顯示以下錯誤。

代碼2：未提供PhotoImage對象時。

# Importing Tkinter module 
from tkinter import * from tkinter.ttk import *
  
# Creating master Tkinter window 
master = Tk() 
  
# Setting icon of master window 
master.iconphoto(False, 'info.png') 
  
# Creating button 
b = Button(master, text = 'Click me !') 
b.pack(side = TOP) 
  
# Infinite loop can be terminated by 
# keyboard or mouse interrupt 
# or by any predefined function (destroy()) 
mainloop()

輸出：
