【python】tkinter 设置ico和调整背景颜色_tkinter设置背景颜色默认

•  设置ico

首先生成一个ico文件，可以通过https://www.bitbug.net在线通过图片生成

其次将ico文件通过base64编码，转成一个ico.py资源文件

import base64
 
open_icon = open("ico.ico","rb") 
b64str = base64.b64encode(open_icon.read()) 
open_icon.close()
write_data = 'img=%s' % b64str
f = open("ico.py","w")  
f.write(write_data)
f.close() 

再次在程序中引用ico.py，并解码图片并展示，从而达到编译时有ico

from tkinter import *
from tkinter.ttk import *
import os
from ico import img
import base64
 
def app_gui_start():
    init_window = Tk() 
    # 设置窗口最大化按钮不可用
    init_window.resizable(0,0)
    #程序运行时在屏幕中间打开
    sw = init_window.winfo_screenwidth()
    sh = init_window.winfo_screenheight()
    ww = 600
    wh = 400
    x = (sw-ww) / 2
    y = (sh-wh) / 2
    init_window.title("app client")
    init_window.geometry("%dx%d+%d+%d" %(ww,wh,x,y))   
    # 设置窗口的图标和编译exe的图标
    tmp = open("tmp.ico","wb+")  
    tmp.write(base64.b64decode(img))
    tmp.close()
    init_window.iconbitmap("tmp.ico")
    os.remove("tmp.ico") 
    # 窗口其他属性初始化
    # api_PORTAL = app_GUI(init_window)
    # api_PORTAL.set_init_window()
    init_window.mainloop()
 
app_gui_start()
