Tkinter（一）

本篇介绍一下几个知识点：
（1）Label与Button
（2）Entry与Text

（1）Label与Button

import tkinter as tk

window = tk.Tk() #对象，object
window.title('my window')
window.geometry('500x300') #geometry译为几何。

var = tk.StringVar() #是tkinter里面类似字符串的类型
l = tk.Label(window,textvariable = var,bg = 'green',font = ('Arial',12),width = 15,height = 2)
l.pack() #可以用pack放置，也可以明确一个坐标放置


on_hit = False
def hit_me():
    global on_hit
    if on_hit == False:
        on_hit = True
        var.set('you hit me')
    else:
        on_hit = False
        var.set('')


b = tk.Button(window,text = 'hit me',width = 15,height = 2,command = hit_me)
b.pack()

window.mainloop()# 更新窗口数据

自己编写的程序，业余练习01

import tkinter as tk

pingcha = tk.Tk()
pingcha.title('北斗导航系统')
pingcha.geometry('700x500')

#设置两个字符串
var1 = tk.StringVar()
var2 = tk.StringVar()

#设置两个label
l = tk.Label(pingcha,textvariable = var1,bg = 'blue',font = ('Arial',15),width = 20,height = 3)
l.pack()
m = tk.Label(pingcha,textvariable = var2,bg = 'green',font = ('Arial',15),width = 20,height = 3)
m.pack()

#不仅可以放置字符串，也可以放置数字
def LvBoTuiGu():
    a1 = 45
    a2 = 98
    a3 = a1-a2
    a4 = a1+a2
    if a1>a2:
        var2.set(a3)
    else:
        var2.set(a4)


var1.set('近代平差理论')
anniu1 = tk.Button(pingcha,text = '最小二乘与滤波',width = 25,height = 3,command = LvBoTuiGu)
anniu1.pack()

（2）Entry与Text

import tkinter as tk

window = tk.Tk() #对象，object
window.title('my window')
window.geometry('500x300')

e = tk.Entry(window,show = '6')#show = '*'
e.pack()

def insert_point():
    var = e.get()
    t.insert('insert',var)

def insert_end():
    var = e.get()
    t.insert('end',var)#t.insert(1.1,var),第一行，第一位


b1 = tk.Button(window,text = 'insert point',width = 15,height = 2,command = insert_point)
b1.pack()
b2 = tk.Button(window,text = 'insert end',width = 15,height = 2,command = insert_end)
b2.pack()


t = tk.Text(window,height = 2)
t.pack()

window.mainloop()# 更新窗口数据
# entry text

自己编写的程序，业余练习02

import tkinter as tk
import string

w1 = tk.Tk()

w1.title('北斗导航系统')
w1.geometry('500x300')

e1 = tk.Entry(w1,show = '')
e1.pack()

e2 = tk.Entry(w1,show = '')
e2.pack()


def plus():
    var1 = float(e1.get()) #接受两个数字，转换为数字型
    var2 = float(e2.get())

    var3 = var1-var2
    var4 = var3*var1

    t.insert('insert',var4) #将最终的计算结果，插入到t里面

b1 = tk.Button(w1,text = '最小二乘配置解',width = 15,height = 2,command = plus)
b1.pack()

t = tk.Text(w1,height = 2)
t.pack()
