      可以編寫(xiě)出帶頁(yè)面的程序,不過(guò)由于界面不夠美化一般都是安裝程序中用到這些,僅僅對(duì)每個(gè)控件進(jìn)行代碼演示。


      Tkinter主體:

      import tkinter

      # 創(chuàng)建主窗口?

      win = tkinter.Tk()

      # 設(shè)置窗口標(biāo)題?

      win.title("sunck")

      # 設(shè)置窗口大小與位置?

      win.geometry("400x400+200+0")

      # 進(jìn)入消息循環(huán)

      # ??程序運(yùn)行起來(lái)?

      win.mainloop()

      label控件

      import tkinter

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      # win表示主窗體?

      # text:文本內(nèi)容?

      # bg:背景顏色?

      # fg:字體顏色

      # font:字體型號(hào)與大小?

      # anchor:位置  N  NE  E  SE  S  SW  W  NW  CENTER?

      # width:空間寬度?

      # wraplength:指定text中文本多少寬度后開(kāi)始換行

      # justify:text中多行文本的對(duì)齊方式

      l = tkinter.Label(win, text="sunckisagoodman", bg="pink", fg="red", font=("Arial",12), anchor=tkinter.SW, width=10, height=3, wraplength = 30, justify="right")

      # 顯示控件?

      l.pack()

      win.mainloop()

      button控件

      import tkinter

      def func():

           print("sunck is a good man")

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      # 創(chuàng)建按鈕?

      # 顯示窗口?

      # 文本?

      # 點(diǎn)擊按鈕響應(yīng)的方法?

      button=tkinter.Button(win, text="按鈕", width=10, height=10, command=func)

      button.pack()

      button1=tkinter.Button(win, text="按鈕1", command=lambda :print("sunck is a nice man"))

      button1.pack()

      win.mainloop()

      entry控件

      import tkinter

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      # 綁定變量?

      var = tkinter.Variable()

      e = tkinter.Entry(win, textvariable=var, show="*")

      e.pack()

      # 設(shè)置文本框中的值?

      var.set("sunck is a good man")

      # 獲取文本框中的值?

      print(var.get())

      print(e.get())

      win.mainloop()

       

      5、點(diǎn)擊button將entry上的內(nèi)容打印出來(lái)

      import tkinter

      def func():

           print(ve.get())

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      ve = tkinter.Variable()

      e = tkinter.Entry(win, textvariable=ve)

      e.pack()

      button=tkinter.Button(win, text="顯示", command=func)

      button.pack()

      win.mainloop()

      6、text控件

      import tkinter

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      #height:控制顯示行數(shù)

      t = tkinter.Text(win, width=30, height=4)

      t.pack()

      # t.pack(side=tkinter.LEFT, fill=tkinter.Y) #滾動(dòng)條寫(xiě)法

      info = """HAMLET: To be, or not to be--that is the question:

      Whether 'tis nobler in the mind to suffer

      The slings and arrows of outrageous fortune

      Or to take arms against a sea of troubles

      And by opposing end them. To die, to sleep--

      No more--and by a sleep to say we end

      The heartache, and the thousand natural shocks

      That flesh is heir to. 'Tis a consummation

      Devoutly to be wished."""

      #插入

      t.insert(tkinter.INSERT, info)

      win.mainloop()

      7、帶滾動(dòng)條的text

      import tkinter

      win = tkinter.Tk()

      win.title("sunck")

      # win.geometry("400x400+200+0")

      s = tkinter.Scrollbar()

      s.pack(side=tkinter.RIGHT, fill=tkinter.Y)

      t = tkinter.Text(win, width=30, height=4)

      t.pack(side=tkinter.LEFT, fill=tkinter.Y)

      s.config(command=t.yview)

      t.config(yscrollcommand=s.set)

      info = """HAMLET: To be, or not to be--that is the question:

      Whether 'tis nobler in the mind to suffer

      The slings and arrows of outrageous fortune

      Or to take arms against a sea of troubles

      And by opposing end them. To die, to sleep--

      No more--and by a sleep to say we end

      The heartache, and the thousand natural shocks

      That flesh is heir to. 'Tis a consummation

      Devoutly to be wished."""

      t.insert(tkinter.INSERT, info)

      win.mainloop()

      8、CheckButton多選框控件

      from tkinter import *

      def updata():

          message = ""

          if hobby1.get() == 1:

              message += "Your Hobby is 1\n"

          if hobby2.get() == 1:

              message += "Your Hobby is 2\n"

          if hobby3.get() == 1:

              message += "Your Hobby is 3\n"

          txt.delete(0.0, END)#全部刪除txt內(nèi)容

          txt.insert(0.0, message)

      win = Tk()

      win.title("sunck")

      label=Label(win,text = "Please check")

      label.pack()

      hobby1 = BooleanVar()

      checkb1 = Checkbutton(win,text = "hobby1",variable = hobby1,command = updata)

      checkb1.pack()

      hobby2 = BooleanVar()

      checkb2 = Checkbutton(win,text = "hobby2",variable = hobby2,command = updata)

      checkb2.pack()

       

      hobby3 = BooleanVar()

      checkb3 = Checkbutton(win,text = "hobby3",variable = hobby3,command = updata)

      checkb3.pack()

      txt = Text(win,width = 50,height = 5,wrap = WORD)

      txt.pack()

      win.mainloop()

      9、RadioButton單選框控件

      from tkinter import *

      def updata():

          print(v.get())

      win = Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      v = IntVar()

      Radiobutton(win, text="One", variable=v, value=1, command=updata).pack()

      Radiobutton(win, text="Two", variable=v, value=2, command=updata).pack()

      mainloop() 

      10、Listbox控件基本使用

      from tkinter import *

      win = Tk()

      win.title("sunck")

      # win.geometry("400x400+200+0")

      # 1、創(chuàng)建一個(gè)Listbox,向其中添加三個(gè)item

      # lb = Listbox(win, selectmode = BROWSE)

      # for item in ['good', 'nice', 'handsom', "grace", "noble", "sense"]:

      #     #按順序向后添加

      #     lb.insert(END, item)

      # lb.pack()

      # 在開(kāi)始添加

      # lb.insert(ACTIVE, "cool")

      # 只添加一項(xiàng)將[]作為一個(gè)item

      # lb.insert(END,["1","2","3"])

      # 刪除  第一個(gè)為開(kāi)始的索引值;第二個(gè)為結(jié)束的索引值,如果不指定則只刪除第一個(gè)索引項(xiàng)

      # lb.delete(1,3)

      # lb.delete(1)

      # 選中函數(shù),selection_set函數(shù)有兩個(gè)參數(shù)第一個(gè)為開(kāi)始的索引;第二個(gè)為結(jié)束的索引,如果不指定則只選中第一個(gè)參數(shù)指定的索引項(xiàng)

      # lb.select_set(2, 4)

      # 取消選中

      # lb.select_clear(2,4)

      # 得到當(dāng)前Listbox中的item個(gè)數(shù)

      # print(lb.size())

      # 返回指定索引的項(xiàng),參數(shù)第一個(gè)為開(kāi)始的索引;第二個(gè)為結(jié)束的索引,如果不指定則只選中第一個(gè)參數(shù)指定的索引項(xiàng)

      # print(lb.get(1, 3))

      # print(lb.get(1))

      # 返回當(dāng)前返回的項(xiàng)的索引,不是item的值

      # print(lb.curselection())

      # 判斷 一個(gè)項(xiàng)是否被選中,使用索引

      # print(lb.selection_includes(2))

      # print(lb.selection_includes(5))

      # 2、與BROWSE相似 的為SINGLE,但不支持鼠標(biāo)移動(dòng)選中位置

      # v = StringVar()

      # lb = Listbox(win, selectmode = SINGLE, listvariable=v)

      # for item in ['good', 'nice', 'handsom']:

      #     lb.insert(END, item)

      # lb.pack()

      # 打印當(dāng)前列表中的項(xiàng)值

      # print(v.get())

      # 改變v的值,使用tuple可以與item對(duì)應(yīng)

      # v.set(('1000','200'))

      # 事件綁定

      # def printList(event):

      #     print(lb.get(lb.curselection()))

      # lb.bind('<Double-Button-1>',printList)

      # 3、使用selectmode  = EXPANDED使用Listbox來(lái)支持Shift和Control

      # lb = Listbox(win, selectmode = EXTENDED)

      # for item in ['good', 'nice', 'handsom', "grace", "noble", "sense", 1, 2, 3, 4, 5, 6]:

      #     lb.insert(END, item)

      # lb.pack()

      # # 運(yùn)行程序,點(diǎn)中“python",shift + 點(diǎn)擊"widget",會(huì)選中所有的item

      # # 運(yùn)行程序,點(diǎn)中"python",control + 點(diǎn)擊"widget",會(huì)選中python和widget,第二項(xiàng)tkinter處于非選中狀態(tài)

      # # 滾動(dòng)條控件

      # # 當(dāng)內(nèi)容超過(guò)可視化區(qū)域時(shí)使用,如列表框

      # scrl = Scrollbar(win)

      # scrl.pack(side=RIGHT,fill=Y)

      # # 指定Listbox的yscrollbar的回調(diào)函數(shù)為Scrollbar的set,表示滾動(dòng)條在窗口變化時(shí)實(shí)時(shí)更新

      # lb.configure(yscrollcommand=scrl.set)

      # lb.pack(side=LEFT,fill=BOTH)

      # # # 指定Scrollbar的command的回調(diào)函數(shù)是Listbar的yview

      # scrl['command'] = lb.yview

      # 4、創(chuàng)建一個(gè)可以多選的Listbox,使用屬性selectmaod

      lb = Listbox(win, selectmode = MULTIPLE, )

      for item in ['good', 'nice', 'handsom']:

          lb.insert(END, item)

      lb.pack()

      win.mainloop()

      11、Scale控件

      # Tkinter 中的 Scale 控件是一種可供用戶通過(guò)拖動(dòng)指示器改變變量值的控件. 這種控件可以水平放置, 也可以豎直放置

      from tkinter import *

      win = Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      # 豎

      # from起始值

      # to結(jié)束值

      # tickinterval選擇值將會(huì)變?yōu)樵摂?shù)值的倍數(shù)

      # length 豎直時(shí)為高度,水平是為長(zhǎng)度

      scale1 = Scale(win, from_=0, to=40, tickinterval=8, length=300)

      scale1.pack()

      #默認(rèn)值為起始值,可以通過(guò)set賦值

      scale1.set(20)

      # 獲取值

      # def show():

      #     print(scale1.get())

      # Button(win, text="show", command=show).pack()

      #橫 orient=HORIZONTAL

      # scale2 = Scale(win, from_=0, to=200, orient=HORIZONTAL)

      # scale2.pack()

      win.mainloop()

      12、Spinbox控件

      from tkinter import *

      win = Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      def change():

          print(v.get())

      v = StringVar()

      # from_:最小值

      # to:最大值

      # increment:步長(zhǎng)

      # values:每次更新值將使用values指定的值,不要和from_與to同時(shí)使用values=(0,2,4,6,8)

      sp = Spinbox(win, from_=0, to=100, increment=1, textvariable=v, command=change)

      sp.pack()

      #設(shè)置值

      v.set(20)

      #取值

      print(v.get())

      win.mainloop()

      13、Menu頂層菜單

      from tkinter import *

      def callback():

          print("sunck is a good man")

      win = Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      menubar = Menu(win)

      win.config(menu=menubar)

       

      filemenu = Menu(menubar, tearoff=False)

      for item in ['Python', 'PHP', 'CPP', 'C', 'Java', 'JavaScript', 'VBScript', "退出"]:

          if item == "退出":

              filemenu.add_separator()

              filemenu.add_command(label=item, command=win.quit)

          else:

              filemenu.add_command(label=item, command=callback)

      filemenu2 = Menu(menubar, tearoff=False)

      #accelerator快捷鍵

      filemenu2.add_command(label="顏色設(shè)置", command=callback, accelerator='Ctrl+N')

      filemenu2.add_command(label="字體設(shè)置")

      menubar.add_cascade(label="語(yǔ)言", menu=filemenu)

      menubar.add_cascade(label="設(shè)置", menu=filemenu2)

      win.mainloop()

      14、Menu右鍵菜單

      from tkinter import *

      win = Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      menubar = Menu(win)

      def callback():

          print('sunck is a good man')

      filemenu = Menu(menubar, tearoff=0)

      for k in ['Python', 'PHP', 'CPP', 'C', 'Java', 'JavaScript', 'VBScript']:

          filemenu.add_command(label=k, command=callback)

          filemenu.add_separator()

      menubar.add_cascade(label='語(yǔ)言', menu=filemenu)

      def popup(event):

          menubar.post(event.x_root, event.y_root)

      win.bind('<Button-3>', popup)

      win.mainloop()

      15、Frame控件

      import tkinter

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      tkinter.Label(win, text="frame", bg="red", font=("Arial",15)).pack()

      frm = tkinter.Frame(win)

      frm.pack()

      # #left

      frm_L = tkinter.Frame(frm)

      tkinter.Label(frm_L, text="左上", bg="pink", font=("Arial",12)).pack(side=tkinter.TOP)

      tkinter.Label(frm_L, text="左下", bg="green", font=("Arial",12)).pack(side=tkinter.TOP)

      frm_L.pack(side=tkinter.LEFT)

      #right

      tkinter.Label(frm_R, text="右上", bg="yellow", font=("Arial",12)).pack(side=tkinter.TOP)

      tkinter.Label(frm_R, text="右下", bg="purple", font=("Arial",12)).pack(side=tkinter.TOP)

      frm_R.pack(side=tkinter.RIGHT)

      win.mainloop()

      16、Combobox下拉控件

      import tkinter

      from tkinter import ttk

      def func(*args):

          # 當(dāng)前選中的值

          print(comboxlist.get())

      win = tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      var = tkinter.StringVar()

      comboxlist = ttk.Combobox(win, textvariable = var)

      # 設(shè)置下拉數(shù)據(jù)

      comboxlist["value"] = ("1","2","3","4","5")

      # 默認(rèn)現(xiàn)實(shí)的值的下標(biāo)

      comboxlist.current(0)

      # 綁定事件

      comboxlist.bind("<<ComboboxSelected>>", func)

      from tkinter import ttk

      win=tkinter.Tk()

      win.title("sunck")

      win.geometry("400x400+200+0")

      tree=ttk.Treeview(win)

      tree.pack()

      #一級(jí)樹(shù)枝

      treeF1=tree.insert("",0,"中國(guó)",text="中國(guó)CHI",values=("F1"))

      treeF2=tree.insert("",1,"美國(guó)",text="美國(guó)USA",values=("F2"))

      treeF3=tree.insert("",2,"英國(guó)",text="英國(guó)ENG",values=("F3"))
