我试图让我的程序上的按钮执行操作,但我不是100%如何做到这一点。我已经创建了按钮,希望它们是正确的,但只需要一些关于如何使它们工作的建议!所以当我点击按钮"添加rect"它应该在随机位置添加一个随机矩形,反之亦然,以便删除。
from tkinter import *
import random
root = Tk()
class Recta:
def __init__(self, height, width):
self.height=60
self.width=80
def randomRects(self,canvas):
w = random.randrange(80)
h = random.randrange(60)
canvas.create_rectangle(0,0,h,w,fill='green')
def create_buttons(self,canvas):
frame = Frame(root, bg='grey', width=400, height=40)
frame.pack(fill='x')
frame = Frame(root, bg='grey', width=400, height=40)
frame.pack(fill='x')
button1 = Button(frame, text='Add Rect')
button1.pack(side='left', padx=10)
button2 = Button(frame, text='Remove Rect')
button2.pack(side='left')
def removeRects(self,canvas):
self.myRect = canvas.create_rectangle(0, 0, w, h, fill='green')
canvas.delete(self.myRect)
c = Canvas(root)
c.pack()
tes = Recta(10,20)
tes.randomRects(c)
tes.create_buttons(1)
root.mainloop()
答案 0 :(得分:1)
您的代码需要进行严格的重组。
这是可以添加矩形的东西。你没有提供remove rectangle
方法,所以我让你写出来 - 此时,delete button
来电randomRect
;你可能需要跟踪你在某种集合中创建的矩形,以便能够删除它们。

self.canvas.create_rectangle(0, 0, w, h, fill='green')
