Tkinter的entry组件

Entry组件就是输入框：

例如程序要输入帐号密码，那么它就需要提供两个输入框给你

最简单的输入框显示：

from tkinter import \*

root = Tk()

e = Entry(root)  
e.pack(padx=20, pady=20)

e.delete(0, END)  
e.insert(0, "默认文本...")

mainloop()

运行：

获取输入框中的内容，使用Entry组件的get()方法

看例子，单击按钮时，获得输入框中的内容并打印出来，然后清空输入框：

from tkinter import \*

root = Tk()

Label(root,text="作品：").grid(row=0, column=0)  
Label(root,text="作者：").grid(row=1, column= 0)

e1 = Entry(root)  
e2 = Entry(root)  
e1.grid(row=0, column=1, padx=10, pady=5)  
e2.grid(row=1, column=1, padx=10, pady= 5)

def show():  
print("作品：《%s》" % e1.get())  
print("作品：%s" % e2.get())  
e1.delete(0,END)  
e2.delete(0,END)

Button(root, text="获取信息", width=10, command=show)\\  
.grid(row=3, column=0, sticky=W, padx=10, pady=5)  
Button(root, text="退出", width=10, command=root.quit)\\  
.grid(row=3, column=1, sticky=E, padx=10, pady= 5)

mainloop()

如果想设计一个密码输入框，即需要用\*代替输入的内容，只需要设置show选项

from tkinter import \*

root = Tk()

Label(root, text="账号：").grid(row=0, column=0)  
Label(root, text="密码：").grid(row=1, column=0)

v1 = StringVar()  
v2 = StringVar()

e1 = Entry(root, textvariable=v1)  
e2 = Entry(root, textvariable=v2, show="\*")  
e1.grid(row=0, column=1, padx=10, pady=5)  
e2.grid(row=1, column=1, padx=10, pady=5)

def show():  
print("账号：%s" % e1.get())  
print("密码：%s" % e2.get())

Button(root, text="注册", width=10, command=show)\\  
.grid(row=3, column=0, sticky=W, padx=10, pady=5)  
Button(root, text="退出", width=10, command=root.quit)\\  
.grid(row=3, column=1, sticky=E, padx=10, pady=5)

mainloop()
