Tkinter之Radiobutton篇
Radiobutton为单选按钮,即在同一组内只能有一个按钮被选中,每当选中组内的一个按钮时,其它的按钮自动改为非选中态,与其他控件不同的是:它有组的概念

#回调函数
def callRadiobutton():
print('python is good!')
def callRadobuttonPrint(v):
print(v)
if __name__ == '__main__':
root = tk.Tk()
root.wm_title('Radiobutton')
root.geometry("1800x800+120+100") #设置窗口大小 并初始化桌面位置
root.resizable(width = True,height = True) #宽不可变 高可变 默认True
#不指定绑定变量,每个Radiobutton自成一组
fram = Frame(root)
Radiobutton(fram,text = 'python').pack(side = LEFT)
Radiobutton(fram,text = 'python1').pack(side = LEFT)
Radiobutton(fram,text = 'python2').pack(side = LEFT)
fram.pack(side = TOP)
#1、不指定绑定变量,每个Radiobutton自成一组
fram1 = Frame(root)
v = IntVar()
v.set(1)
for i in range(3):
Radiobutton(fram1,variable = v,text = 'python',value = i).pack(side = LEFT)
fram1.pack(side = TOP)
#2、创建两个不同的组
fram2 = Frame(root)
v1 = IntVar()
v2 = IntVar()
v1.set(1)
v2.set(2)
for v in [v1,v2]: #创建两个组
for i in range(3): #每个组含有3个按钮,不同的组,各个按钮互不影响。
Radiobutton(fram2,variable = v,
text = 'python',
value = i,
command = callRadiobutton).pack(side = LEFT)

#3、如果同一个组中的按钮使用相同的value,则这两个按钮的工作方式完全相同
fram3 = Frame(root)
v = IntVar()
v.set(1)
for i in range(3):
Radiobutton(fram3,variable = v,
text = 'value值是:' + str(1),

Radiobutton(fram3,variable = v,
text = 'value值是:' + str(i),
value = i).pack(side = LEFT)
#上述的例子中共有4个value为1的值,当选中其中的一个时,其他三个也会被选中;选中除了这四个只外的按钮时,四个按钮全部取消
fram3.pack(side = TOP)
#4、与Checkbutton类似,每个Radiobutton可以有自己的处理函数,每当点击按钮时,系统会调用相应的处理函数
fram4 = Frame(root)
v = IntVar()
v.set(1)
for i in range(3):
Radiobutton(fram4,variable = v,
text = 'python' + str(i),

v = IntVar()
v.set(0)
def r1():
print('call r1')
def r2():
print('call r2')
def r3():
print('call r3')
def r4():
print('call r4')
i = 0
# 创建8个按钮,其中两个两个的value值相同
# 注意虽然同时可以选中两个按钮,但每次点击按钮,执行的代码只有一次
for r in [r1,r2,r3,r4]:
for i in range(3):
Radiobutton(fram5,variable = v,
text = 'python' + str(i),
value = i,
bg = 'green',
command = r).pack(side = LEFT)
for i in range(3):
Radiobutton(fram5,variable = v,
text = 'python' + str(i),
value = i,
fg = 'red',
command = r).pack(side = LEFT)
i += 1
fram5.pack(side = TOP)
#6、Radiobutton另一个比较实用的属性是indicatoron,缺省情况下为1,如果将这个属性改为0,则其外观是Sunken
# Radiobutton表示按钮的弹起或按下两种状态
fram6 = Frame(root)
Radiobutton(fram6,indicatoron = 1,
text = 'python1').pack(side = LEFT)
Radiobutton(fram6,indicatoron = 0,
text = 'python1').pack(side = LEFT)
Radiobutton(fram6,indicatoron = 1,
text = 'python1',
width = 10,height = 5).pack(side = LEFT)
fram6.pack(side = TOP)
