Python基础入门学习笔记 066 GUI的终极选择：Tkinter3

实例1：Checkbutton 组件 1 fr tkinter import * 2 3 root = Tk() 4 #需要一个Tkinter变量，用于表示该按钮是否被选中 5 v = IntVar() 6 c = Checkbutton(root,text="测试一下",variable = v) 7 8 c.pack() 9 #如果被选中，那么变量v被赋值为1，否则为0 10 #可以用个Label标签动态地给大家展示： 11 lable = Label(root,textvariable = v) 12 lable.pack() 13 14 mainloop()

实例2：

1 fr tkinter import * 2 3 root = Tk() 4 5 GIRLS = ["貂蝉","王昭君","西施","杨玉环"] 6 v = [] 7 for girl in GIRLS: 8 v.append(girl) 9 c = Checkbutton(root,text = girl,variable = v[1])#1表示每次取v列表中最后一个元素，即刚加入的那个元素 10 c.pack(anchor = W)#W(western)向左对齐 11 12 mainloop()

实例3：Radiobutton 组件

1 fr tkinter import * 2 3 root = Tk() 4 5 v = IntVar()#如果被选中，v被赋值为1，否则为0 6 Radiobutton(root,text = "One",variable = v,value = 1).pack(anchor = W) 7 #value表示第一个按钮被选中时，v的值赋值给variable 8 9 Radiobutton(root,text = "Two",variable = v,value = 2).pack(anchor = W) 10 11 Radiobutton(root,text = "Three",variable = v,value = 3).pack(anchor = W) 12 13 Radiobutton(root,text = "Four",variable = v,value = 4).pack(anchor = W) 14 15 mainloop()

实例4：循环处理

1 fr tkinter import * 2 3 root = Tk() 4 5 LANGS = [ 6 ("Python",1), 7 ("Perl",2), 8 ("Ruby",3), 9 ("Lua",4)] 10 11 12 v = IntVar()#如果被选中，v被赋值为1，否则为0 13 v.set(1)#将1设置为默认值 14 for lang,num in LANGS: 15 b= Radiobutton(root,text = lang,variable = v,value = num) 16 b.pack(anchor = W) 17 #value表示第一个按钮被选中时，v的值赋值给variable 18 19 mainloop()

实例5：改成按钮形式

1 fr tkinter import * 2 3 root = Tk() 4 5 LANGS = [ 6 ("Python",1), 7 ("Perl",2), 8 ("Ruby",3), 9 ("Lua",4)] 10 11 12 v = IntVar()#如果被选中，v被赋值为1，否则为0 13 v.set(1)#将1设置为默认值 14 for lang,num in LANGS: 15 b= Radiobutton(root,text = lang,variable = v,value = num,indicatoron = False) 16 b.pack(fill = X)#表示横向填充 17 #value表示第一个按钮被选中时，v的值赋值给variable 18 19 mainloop()

实例6：LabelFrame 组件

1 fr tkinter import * 2 3 root = Tk() 4 5 group = LabelFrame(root,text = "最好的脚本语言是？",padx = 10,pady = 10)#按钮相对边框的偏移 6 group.pack(padx = 10,pady = 10)#框架相对边框的偏移 7 8 LANGS = [ 9 ("Python",1), 10 ("Perl",2), 11 ("Ruby",3), 12 ("Lua",4)] 13 14 15 v = IntVar()#如果被选中，v被赋值为1，否则为0 16 v.set(1)#将1设置为默认值 17 for lang,num in LANGS: 18 b= Radiobutton(group,text = lang,variable = v,value = num,indicatoron = False) 19 b.pack(fill = X) 20 #value表示第一个按钮被选中时，v的值赋值给variable 21 22 mainloop()
