【问题描述】:
我尝试将 Tkinter 库用于我在 python 中的小项目。我创建了一个 500 x 500 的正方形,里面有 10000 个小正方形。
并且我希望每个小方块在用户点击时变黑。有人可以告诉我为什么,我真的很感激。这是图形代码:
from Tkinter import *
from button import *
class AppFrame(Frame):
def __init__(self):
self.root = Tk()
self.root.geometry = ("1000x1000")
self.f = Frame(self.root, relief = 'sunken', width = 600, height = 600)
self.w = Canvas(self.f,width = 505, height =505)
##get the x, y value whenever the user make a mouse click
self.w.bind("<Button-1>", self.xy)
self.bolist = []
for k in range(1,101):
for i in range(1, 101):
button = Buttons(self.w, i * 5, k * 5, i * 5 + 5, k * 5 + 5)
self.bolist.append(button)
self.f.grid(column =0, columnspan = 4)
self.w.grid(column = 0)
self.root.mainloop()
def xy (self, event):
self.x, self.y = event.x, event.y
print (self.x, self.y)
##check each button if it's clicked
for hb in self.bolist:
if hb.clicked(self.x, self.y):
print ("hurry")
hb.activate()
还有
##button.py
from Tkinter import *
class Buttons:
def __init__(self,canvas,bx,by,tx,ty):
self.canvas = canvas
self.rec = canvas.create_rectangle((bx,by,tx,ty),fill = "lightgray",
activefill= 'black', outline = 'lightgray')
self.xmin = bx
self.xmax = tx
self.ymin = by
self.ymax = ty
##print (bx, by, tx, ty)
def clicked(self, px, py):
return (self.active and self.xmin <= px <= self.xmax and
self.ymin <= py <= self.ymax)
def activate(self):
self.canvas.itemconfigure(slef.rec, fill = 'black')
self.active = True

-
你得到什么错误?
-
你的代码缩进不对。
