Radiobutton选择

时间：2016-08-27 07:18:16

标签： python tkinter turtle-graphics

我想通过结合Turtle和Tkinter来制作游戏。我的代码运行良好，但我在选择Radiobutton部分时遇到问题。当我尝试选择“黑色”（彩色）单选按钮时，我无法选择它，但是，其他颜色选择没有问题。另一个问题是我想使用“无颜色”选项，当用户选择它时，必须绘制没有填充的形状。但它不起作用，它会自动填充颜色。我不明白它是如何自动选择的。我该如何解决这个问题？

答案 0 :(得分：2)

对于你的第二个问题：

from tkinter import *
root = Tk()

selvar = StringVar()
selvar.set(' ')

rb1 = Radiobutton(root, variable=selvar, value='a')
rb1.pack()
rb2 = Radiobutton(root, variable=selvar, value='b')
rb2.pack()

这是StringVar。对于IntVar：

from tkinter import *
root = Tk()

selvar = IntVar()
selvar.set(0)

rb1 = Radiobutton(root, variable=selvar, value=1)
rb1.pack()
rb2 = Radiobutton(root, variable=selvar, value=2)
rb2.pack()

更新：我发现如果我不对var.set(0)使用IntVar()，它会正常工作（如果我从1开始不是0.实际上，0是什么在程序开始时选择它。但是如果它没有设置为0就不适合你，那就去做吧。无论如何它实际上是安全的。

对于您的第一个问题：您选择了黑色作为背景，白色选择了前景色。现在，当您单击此单选按钮时，点不会显示，因为根据前景色，点的颜色为白色。前景色不仅适用于单选按钮的文本颜色，还适用于单选按钮的点的颜色。因此无法显示白色+白色。
