Message and Entry组件

from tkinter import *
msg = Message(text="Oh by the way, which one‘s Pink?")
msg.config(bg=‘pink‘, font=(‘times‘, 16, ‘italic‘))
msg.pack(fill=X, expand=YES)
mainloop()

from tkinter import *
import sys
def fetch():
    print(‘Input => "%s"‘ % ent.get()) # get text
def quit():
    sys.exit()
root = Tk()
ent = Entry(root)
ent.insert(0, ‘Type words here‘) # set text 插入一个原始默认的文本
ent.pack(side=TOP, fill=X) # grow horiz 获得水平增大
ent.focus() # save a click 保存单击事件
ent.bind(‘<Return>‘, (lambda event: fetch())) # on enter key  当按下回车键时触发
btn = Button(root, text=‘Fetch‘, command=fetch) # and on button 当按下按钮时触发
btn.pack(side=LEFT)
btn1 = Button(root,text=‘QUIT‘,command=quit)
btn1.pack(side=RIGHT)
root.mainloop()

ent.insert(0, ‘some text‘) # set value 保存值
value = ent.get() # fetch value (a string) 获取值
ent.delete(0, END) # first, delete from start to end 清空值
ent.insert(0, ‘some text‘) # then set value 插入值

用entry设计表单

from tkinter import *
fields = ‘Name‘, ‘Job‘, ‘Pay‘
def fetch(entries):
    for entry in entries:
        print(‘Input => "%s"‘ % entry.get()) # get text
def quit():
    sys.exit()
def makeform(root, fields):
    entries = []
    for field in fields:
        row = Frame(root) # make a new row
        lab = Label(row, width=5, text=field) # add label, entry
        ent = Entry(row)
        row.pack(side=TOP, fill=X) # pack row on top
        lab.pack(side=LEFT)
        ent.pack(side=RIGHT, expand=YES, fill=X) # grow horizontal
        entries.append(ent)
    return entries
if __name__ == ‘__main__‘:
    root = Tk()
    ents = makeform(root, fields)
    root.bind(‘<Return>‘, (lambda event: fetch(ents)))
    Button(root, text=‘Fetch‘,command= (lambda: fetch(ents))).pack(side=LEFT)
    Button(root,text=‘QUIT‘,command=quit).pack(side=RIGHT)
    root.mainloop()
