Python GUI 05----Checkbutton

標籤：python

1.一個簡單的Checkbutton例子

from tkinter import *root = Tk()Checkbutton(root,text = 'python').pack()root.mainloop()

2.設定Checkbutton的回呼函數

from tkinter import *def callCheckbutton():    print ('you check this button')root = Tk()Checkbutton(root,text = 'check python',command = callCheckbutton).pack()  #不管Checkbutton的狀態如何，此回呼函數都會被調用root.mainloop()

3.擷取Checkbuton的On與Off的值。預設預設值分別為1和0

from tkinter import *root = Tk()#將一整數與Checkbutton的值綁定，每次點擊Checkbutton，將列印出當前的值v = IntVar()def callCheckbutton():    print (v.get())Checkbutton(root,            variable = v,            text = 'checkbutton value',            command = callCheckbutton).pack()root.mainloop()

from tkinter import *root = Tk()#將一字串與Checkbutton的值綁定，每次點擊Checkbutton，將列印出當前的值v = StringVar()def callCheckbutton():    print v.get()Checkbutton(root,            variable = v,            text = 'checkbutton value',            onvalue = 'python',                 #設定On的值            offvalue = 'tkinter',               #設定Off的值            command = callCheckbutton).pack()root.mainloop()
