python checkbox 用法详解

python checkbox 用法,我用举了很多实例来检测表单的各种状态，下面一个个实现带图给大参考吧。

检测表单是否disabled了，代码如下

from Tkinter import *

class Dummy: pass
var = Dummy()

root = Tk()
root.title('Checkbutton')
for castmember, row, col, status in [
    ('A', 0,0,NORMAL), ('B', 0,1,NORMAL),
    ('C', 1,0,DISABLED), ('D', 1,1,NORMAL),
    ('E',2,0,NORMAL), ('F', 2,1,NORMAL)]:
    setattr(var, castmember, IntVar())
    Checkbutton(root, text=castmember, state=status, anchor=W,
      variable = getattr(var, castmember)).grid(row=row, column=col, sticky=W)
root.mainloop()

检测表单的状态

# check buttons, the easy way

from Tkinter import *     
root = Tk()
states = []                
for i in range(10):
    var = IntVar()
    chk = Checkbutton(root, text=str(i), variable=var)
    chk.pack(side=LEFT)
    states.append(var)
root.mainloop()                              
print map((lambda var: var.get()), states) 

保存表单状态

from Tkinter import *     
states = []
def onPress(i):                      
    states[i] = not states[i]  

root = Tk()
for i in range(10):
    chk = Checkbutton(root, text=str(i), command=(lambda i=i: onPress(i)) )
    chk.pack(side=LEFT)
    states.append(0)
root.mainloop()
print states 

检测一个表单

from Tkinter import *

class AllTkinterWidgets:
    def __init__(self, master):
        frame = Frame(master, , , bd=1)
        frame.pack()

        iframe1 = Frame(frame, bd=2, relief=SUNKEN)
        Button(iframe1, text='Button').pack(side=LEFT, padx=5)
        Checkbutton(iframe1, text='CheckButton').pack(side=LEFT, padx=5)

        v=IntVar()
        Radiobutton(iframe1, text='Button', variable=v,
                    value=3).pack(side=RIGHT, anchor=W)
        Radiobutton(iframe1, text='Dio', variable=v,
                    value=2).pack(side=RIGHT, anchor=W)
        Radiobutton(iframe1, text='Ra', variable=v,
                    value=1).pack(side=RIGHT, anchor=W)
        iframe1.pack(expand=1, fill=X, pady=10, padx=5)

   
root = Tk()
#root.option_add('*font', ('verdana', 10, 'bold'))
all = AllTkinterWidgets(root)
root.title('Tkinter Widgets')
root.mainloop()

增加一个对话框

from Tkinter import *
import tkSimpleDialog

class MyDialog(tkSimpleDialog.Dialog):

    def body(self, master):
        Label(master, text="First:").grid(row=0, sticky=W)
        Label(master, text="Second:").grid(row=1, sticky=W)
   
        self.e1 = Entry(master)
        self.e2 = Entry(master)
   
        self.e1.grid(row=0, column=1)
        self.e2.grid(row=1, column=1)
   
        self.cb = Checkbutton(master, text="Hardcopy")
        self.cb.grid(row=2, columnspan=2, sticky=W)
   
    def apply(self):
        first = self.e1.get()
        second = self.e2.get()
        print first, second

root = Tk()
d = MyDialog(root)
print d.result
