Python self-study-class14(down)-design basis of window interface

1. Basics:
Learn how to call tkinter to create a form and add the required functions (buttons, text boxes, form background, etc.) to the created form

#coding=gbk
import tkinter
from tkinter import ttk
def go():
    print("hello go")
win = tkinter.Tk()  #构造窗体

win.title("hello python")
win.geometry("800x800+300+0")

button=tkinter.Button(win,text="点一下看看撒",command = go)#,width = 10,height=10)
button.pack()   #加载到窗体
button1=tkinter.Button(win,text="点一下看看撒",command =lambda :print("你好呀"))
label = tkinter.Label(win,text = "hello python")  #标签
button1.pack()   #加载到窗体
#button.place(10,10)
newlabel = tkinter.Label(win,#父窗体
                         anchor = tkinter.CENTER,  #位置
                         bg = "blue",   #背景颜色
                         fg = "yellow", #标签颜色
                         text = "gogogi",  #文本
                         width = 10,
                         height = 10)
newlabel.pack()

#文本输入框
entry = tkinter.Entry(win,width=50,bg="red",fg="black")
entry.pack()

#list显示查询数据
mylist = tkinter.Listbox(win,width=50)  #列表框
mylist.pack()
for item in ["1","sasda","sdasd"]:   #内容插入
    mylist.insert(tkinter.END,item)

#数据选择查询
def go1(*args):  #处理事件
    print(comboxlist.get()) #选中当前的值
comvalue = tkinter.StringVar() #窗体自带文本，新建一个值
comboxlist = ttk.Combobox(win,textvariable=comvalue)  #初始化
comboxlist["values"] = ("1","2","3","4")
comboxlist.current(0)  #选择第一个
comboxlist.bind("<<ComboboxSelected>>",go1)  #绑定事件与函数
comboxlist.pack()


win.mainloop()   #进入消息循环

Running effect:

2. Basic application
of the form This part has learned some applications of the form and binding of events

#coding=gbk
import tkinter
import os
from tkinter import ttk
def go():
    print(entry.get())    #返回输入的文本
    if entry.get() == "记事本":
        os.system("notepad")

win = tkinter.Tk()
entry = tkinter.Entry(win)  #input
entry.pack()
button = tkinter.Button(win,text="搜索",command=go)
button.pack()

#文本编辑器
text = tkinter.Text(win)
text.insert(tkinter.INSERT,"hello")#插入文本
text.insert(tkinter.INSERT,"\r\n")#换行
text.insert(tkinter.INSERT,"hello")#插入文本
text.pack()

#树状
tree=ttk.Treeview(win)   #表格
tree.pack()
tree["columns"] = ("姓名","年龄","身高")
tree.column("姓名",width=100)   #表示列,不显示
tree.column("年龄",width=100)
tree.column("身高",width=100)
tree.heading("姓名",text="姓名")  #显示表头
tree.heading("年龄",text="年龄")  #显示表头
tree.heading("身高",text="身高")  #显示表头
txm=tree.insert("",0,text="line1",values=("txm","21","176"))  #插入具体值
tree.insert("",1,text="line2",values=("txm","21","176"))
txm1 = tree.insert(txm,1,text="line1",values=("tmm","21","176"))  #创建树状结构
txm2 = tree.insert(txm,0,text="line2",values=("tmm","21","176"))  #创建树状结构


win.mainloop()

3. Follow the tutorial to complete the advanced use of the form (data search visualization)
1) Because a larger txt data file is needed, I randomly created a

2) main function part (mainClass):

#coding=gbk
import 数据搜索可视化.inputview
import 数据搜索可视化.ListShowdata
import 数据搜索可视化.BigDataFind

myinput = 数据搜索可视化.inputview.InputView()
myinput.show()



'''
bigfind = 数据搜索可视化.BigDataFind.bigdatafind("D:\\Python代码\\class14\\数据搜索可视化\\bigdata.txt")
bigfind.find("tmy")
bigfind.show()

#myinput = 数据搜索可视化.inputview.InputView()
#myinput.show()

myshow = 数据搜索可视化.ListShowdata.showdatainlist()
myshow.adddata("ajskahdja")
myshow.show()
'''

3) Data Find Module (BigDataFind):

#coding=gbk
import codecs
import 数据搜索可视化.ListShowdata
class bigdatafind:
    def __init__(self,path):
        self.file = codecs.open(path,"rb","GBK","ignore")  #打开文件
        self.showdata = 数据搜索可视化.ListShowdata.showdatainlist()
    def find(self,searchstr):
        while True:
            line = self.file.readline()  #按行读入
            if line.find(searchstr) != -1:  #非空则显示
                print(line,end="")  #显示数据
                self.showdata.adddata(line)  #插入
            if not line:  #没有数据即退出
                break

    def show(self):
        self.showdata.show()

4) Form input module (inputview):

#coding=gbk
import tkinter
import 数据搜索可视化.BigDataFind

class InputView:
    def __init__(self):
        self.win = tkinter.Tk()
        self.win.geometry("800x800+300+0")   #设置界面大小及位置

        self.entry = tkinter.Entry(self.win)  #导入文本框
        self.entry.place(x=0,y=0)
        self.button = tkinter.Button(self.win,text = "搜索",command = self.search)  #导入搜索键，command表示绑定search的行为
        self.button.place(x=200,y=0)

    def search(self):
        print("start search",self.entry.get())  #在运行窗口输出搜索的内容
        bigfind = 数据搜索可视化.BigDataFind.bigdatafind(r"D:\Python代码\class14\数据搜索可视化\bigdata.txt") #数据搜索，对象绑定数据
        bigfind.find(self.entry.get())  #find查找符合所搜索的文本
        bigfind.show()

    def show(self):
        self.win.mainloop()

5) Data list display module (ListShowdata):

#coding=gbk
import tkinter
class showdatainlist:
    def __init__(self):
        self.win = tkinter.Tk()
        self.win.geometry("800x800+300+0")   #搜索数据显示窗口
        self.list = tkinter.Listbox(self.win,width=800,height=800)   #控制输出列表大小
        self.list.pack()
    def show(self):
        self.win.mainloop()
    def adddata(self,insertstr):
        self.list.insert(tkinter.END,insertstr)  #插入数据

6) The total function list: The

running effect is as follows:


Summary:
Finally, the data search visualization has made a very good summary of the basics of the previously learned form. Although it is just done by following the tutorial, a careful understanding can be familiar with the application design of the form , It can also strengthen the understanding and application of the relationship between classes;
