参数说明:
注意:pack() 和 grid() 是不能同时使用的
参数说明:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
from tkinter import * from tkinter import messagebox # python3.0的messagebox,属于tkinter的一个组件
top = Tk() #。生成窗口 top.title("grid test") # 窗口标题 top.geometry('300x400') #。窗口大小
def box(): return messagebox.askyesno(title='弹窗', message='内容')
Popup1 = Button(top, text="按钮1", fg="blue", bd=2, width=5, command=box, state="normal") Popup1.grid(row=1, column=1, sticky='E')
Popup2 = Button(top, text="按钮2", fg="yellow", bd=2, width=5, command=box, state="normal") Popup2.grid(row=2, column=2, sticky='NE') |
效果:
:不选yes,不给通过!
这里需要改一下messagebox内的源代码!
1 2 3 4 |
if s == CANCEL or s == NO: return None elif s == YES: return YES |
代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 |
