Question

我无法弄清楚如何在选中时复选框填充对象。我知道我可以使用颜色创建它们，但不知道如何使用复选框更改它们。

from tkinter import *

class box:
    def __init__(self):
        window = Tk()
        window.title("Radiobuttons and Checkbuttons")

        self.canvas = Canvas(window, width = 400, height = 100, bg = 'white')
        self.canvas.pack()

        frame = Frame(window)
        frame.pack()
        frame2 = Frame(window)
        frame2.pack()

        self.v1 = IntVar()
        self.v2 = IntVar()
        cbtFilled = Checkbutton(frame2,text= "Filled",variable = self.v2, command = self.processCheckButton).pack(side=RIGHT)
        rbRect = Radiobutton(frame2, text = "Rectangle", variable = self.v1, value = 1, command = self.processRadiobutton).pack(side=LEFT)
        rbOval = Radiobutton(frame2, text = "Oval", variable = self.v1, value = 2, command = self.processRadiobutton).pack(side = RIGHT)

    def processCheckButton(self):
        if self.v2.get() == 1:
            print("Checked")
        else:
            print("unchecked")

    def processRadiobutton(self):
        if self.v1.get() == 1:
            self.drawRectangle()
        else:
            self.drawOval()

    def drawRectangle(self):
        self.clearCanvas()
        self.canvas.create_rectangle(35, 10 ,350,90,tags = 'rect')

    def drawOval(self):
        self.clearCanvas()
        self.canvas.create_oval(50, 10, 350, 100, tags = 'oval')

    def clearCanvas(self):
        self.canvas.delete('rect','oval')

Answer 1

通过将形状分配给变量，我可以使用itemconfigure（）方法对它们进行祭坛。

self.item=self.canvas.create_oval(50, 10, 350, 100, tags = 'oval')
self.item=self.canvas.create_rectangle(35, 10 ,350,90,tags = 'rect')

def processCheckButton(self):
    if self.v2.get() == 1:
        self.canvas.itemconfigure(self.item,fill='black')
    else:

        self.canvas.itemconfigure(self.item,fill='white')

类框： def init （个体经营）： window = Tk（） window.title（＆＃34; Radiobuttons和Checkbuttons＆＃34;） frame =框架（窗口） frame.pack（） self.canvas = Canvas（frame，width = 400，height = 100，bg =＆＃39; white＆＃39;） self.canvas.pack（）

    frame2 = Frame(window)
    frame2.pack()

    self.v1 = IntVar()
    self.v2 = IntVar()
    cbtFilled = Checkbutton(frame2,text= "Filled",variable = self.v2, command = self.processCheckButton).pack(side=RIGHT)
    rbRect = Radiobutton(frame2, text = "Rectangle", variable = self.v1, value = 1, command = self.processRadiobutton).pack(side=LEFT)
    rbOval = Radiobutton(frame2, text = "Oval", variable = self.v1, value = 2, command = self.processRadiobutton).pack(side = RIGHT)

def processCheckButton(self):
    if self.v2.get() == 1:
        self.clearCanvas()
        if self.v1.get() == 1:
            self.drawRectangle1()
        elif self.v1.get()==2:
            self.drawOval1()
       # print("Checked")

    else:

        #print("unchecked")

def processRadiobutton(self):
    if self.v1.get() == 1:
        self.drawRectangle()
    else:
        self.drawOval()

def drawRectangle(self):
