Tkinter GUI编程——pack

环境安装：

sudo apt-get install python-t

python tkinter 窗口居中对齐：

     from Tkinter import *
     def center_window(w=300, h=200):
         # get screen width and height
         ws = root.winfo_screenwidth()
         hs = root.winfo_screenheight()
         # calculate position x, y
         x = (ws/2) - (w/2)
         y = (hs/2) - (h/2)
         root.geometry('%dx%d+%d+%d' % (w, h, x, y))
     root = Tk()
     center_window(500, 300)
     root.mainloop()

A ScrolledFrame, with several bugs. 

python使用Tk时固定窗口大小：

 from Tkinter import *
 root=Tk()
 root.minsize(50,50)
 root.maxsize(150,150)
 Label(root,text="I'm lly365").pack()
 root.mainloop()

python使用Tkinter做Gui如何显示用forget隐藏的控件:

创建控件
bt=tkinter.Button(root,text='button')
bt.place(x=5,y=5)
bt.place_forget()  #隐藏控件

再次bt.place() 还有传入x=5,y=5 不然不会显示

Python：tkinter-Parent获取弹出窗口的返回值
http://blog.sina.com.cn/s/blog_ac9fdc0b0101naol.html

Tkinter里没有messagebox,
在Python2.5里，要从 tkMessageBox导入
from tkMessageBox import * 然后直接用showinfo()来实现输出 showinfo(message=“hello”) 这个时候不需要使用任何窗口路径来调用它,直接调用它就可以了。
