我认为这是问题所在:
aList 不是全局列表
aListchangecolour()每次运行子程序时都作为本地列表创建
这意味着当你这样做i[1] = 1或i[1] = 0它只改变本地列表时 aList。当子程序再次运行时,aList会创建一个新的作为新的本地列表。
解决aList主程序中定义的问题并使其成为全局列表:
from tkinter import *
class GUI(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
master.title("Window") #Window title
self.pack()
master.geometry("1280x720") #Window size
self.button={}#Dictionary for buttons
self.create_button()
def create_button(self):
indexList =[i for i in range(1000)]
self._button = Button(self, bg='white')
print(self._button.cget('bg'))
xPos = 0
yPos = 0
for index in indexList:
if(yPos == 40):
xPos = xPos + 20
yPos = 0
if(xPos == 10):
yPos = 8
self._button = Button(self, height=2, width=4, command = lambda
i = index: self.changecolour(i))
self.button[index] = self._button
self._button.grid(row=xPos, column =yPos)
yPos = yPos + 1
def changecolour(self,index):
#aList IS NO LONGER CREATED HERE
for i in range(1000):
aList.append([i,0])
for i in aList:
if index == i[0]:
if 0 == i[1]:
self.button[index].configure(bg = 'black')
i[1] = 1
else:
self.button[index].configure(bg = 'white')
i[1] = 0
global aList #MAKE IT A GLOBAL LIST
aList = [] #CREATE THE EMPTY aList LIST
root = Tk()
game_gui = GUI(master=root)
game_gui.mainloop()
