Question

我正在尝试以用户指定的大小初始化蓝色矩形网格。但是，矩形不会在初始化的画布上绘制。我试图将它们存储在矩阵中以供以后操作。我的代码如下：

import Tkinter
import sys
from math import floor

master = Tkinter.Tk()

xboxes = int(sys.argv[1])
yboxes = int(sys.argv[2])

winx = 800
winy = 600

w = Tkinter.Canvas(master, width=winx, height=winy)

squares = [[None]*5 for i in range(5)]
w.pack()
for i in range(yboxes):
    for j in range(xboxes):
        initx = floor(winx / xboxes * j)
        inity = floor(winy / yboxes * i)
        sizex = floor(winx / xboxes * j)
        sizey = floor(winy / yboxes * i)
        squares[i][j] = w.create_rectangle(initx, inity, sizex, sizey, fill="red")

master.mainloop()

知道它为什么不起作用？任何帮助将不胜感激。

我用# <--评论了更改的部分。

create_rectangle接受x1, y1, x2, y2（不是x, y, xsize, ysize）。

try:
    import Tkinter
except ImportError:
    import tkinter as Tkinter
import sys
from math import floor

master = Tkinter.Tk()

xboxes = int(sys.argv[1])
yboxes = int(sys.argv[2])

winx = 800
winy = 600

w = Tkinter.Canvas(master, width=winx, height=winy)

squares = [[None]*xboxes for i in range(yboxes)] # <-- changed hard-coded 5; to use passed argument
w.pack()
for i in range(yboxes):
    for j in range(xboxes):
        initx = floor(winx / xboxes * j) # <--
        inity = floor(winy / yboxes * i) # <--
        endx = floor(winx / xboxes * (j+1)) # <-- with `j`, It draw dot instead of rectangle.
        endy = floor(winy / yboxes * (i+1)) # <--
        squares[i][j] = w.create_rectangle(initx, inity, endx, endy, fill="red")

master.mainloop()

Tkinter不会在Canvas上绘制矩形
