Tkinter Module ("Tk interface") is the interface of Python's standard Tk GUI toolkit

As a practice, using Tkinter to do an ASCII code conversion query Table , this article from four point introduction

Interface

　　

Function

• Query for information by entering characters or numbers
• Query for information by selecting the information in the list

First look at how to produce the first window

From Tkinter import *   #引用Tk模块root = Tk ()             #初始化Tk () root.mainloop ()         #进入消息循环

Several common properties

• Title: Setting the window title
• Geometry: Setting the window size
• Resizable (): Sets whether the window can vary in length and width

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry (' 200x100 ')                 #是x not *root. Resizable (Width=false, height=true) #宽不可变, high variable, default = Trueroot.mainloop ()

Describes the use of several controls

1. Label
2. Frame
3. Entry
4. Text
5. Button
6. Listbox
7. Scrollbar

Explains that each control is finally added with a pack (). Otherwise the control cannot be displayed.

1. Label

Description

Label

Usage

Label (Root object, [property list])

Property

• Text to realistic texts
• BG background Color
• font fonts (color, size)
• Width control widths
• Height Control Heights

The controls described below have almost all of these properties, and more detailed Properties view the reference page

Example

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry (' 300x200 ') L = Label (root, Te Xt= "Show", bg= "green", font= ("Arial", "a"), Width=5, height=2) l.pack (side=left)  #这里的side可以赋值为LEFT  rtght TOP  Bottomroot.mainloop ()

Effect

　　

2. Frame

Description

Create a rectangular area on the screen to layout the form as a container

Usage

Frame (Root object, [property list])

Example

to appear in the control, such four words

Motto

Thick German dedicated

Learned Music Group

can be planned as

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry (' 300x200 ') Label (root, text= ' School motto '. Decode (' GBK '). Encode (' UTF8 '), font= (' Arial ')). Pack () frm = frame (root) #leftfrm_L = Frame (frm) Label (frm_l, Text= ' decode (' GBK '). Encode (' UTF8 '), font= (' Arial ', ()). Pack (Side=top) Label (frm_l, text= ' learned '. Decode (' GBK '). Encode (' UTF8 '), font= (' Arial ', ()). Pack (Side=top) frm_l.pack (side=left) #rightfrm_R = Frame (frm) Label (frm_r, text= ' Dedicated '. Decode (' GBK '). Encode (' UTF8 '), font= (' Arial '), "pack" (side=top) Label (Frm_r, text= ' Le Qun '). Decode (' GBK '). Encode (' UTF8 '), font= (' Arial ', ()). Pack (Side=top) frm_r.pack (side=right) Frm.pack () Root.mainloop ()

Effect

　　

3. Entry

Description

Create a single-line text box

Usage

• Create: LB =entry (Root object, [property list])
• Binding variable Var=stringvar () lb=entry (root object, textvariable = var)
• Gets the value in the text box Var.get ()
• Set the value in the text box Var.set (item1)

Example

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry () var = stringvar () e = Entry ( Root, textvariable = var) var.set ("Hello") e.pack ()    Root.mainloop ()

Effect

　　

4. Text

Description

Enter text into the space

Usage

T = Text (Root object)

Insert: T.insert (mark, content)

Deleted: T.delete (Mark1, MARK2)

Where mark can be a line number, or a special identifier, such as

• Insert: The insertion point of the cursor current: The position of the character that corresponds to the position of the mouse
• End: The last character of this textbuffer
• Sel_first: Selects the first character of the text field, and throws an exception if no area is selected
• Sel_last: Selects the last character of the text field and throws an exception if no area is selected

Example

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry (' 300x200 ') T = Text (root) t.in SERT (1.0, ' hello\n ') t.insert (end, ' hello000000\n ') t.insert (end, ' Nono ') T.pack () Root.mainloop ()

Effect

　　

5. Button

Description

Create button

Usage

Button (Root object, [property list])

Example

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry () def Printhello ():    t.in SERT (' 1.0 ', "hello\n")    t = Text () t.pack () Button (Root, text= "Press", command = Printhello). Pack () Root.mainloop ()

Effect

　　

6. Listbox

Description

List control, can contain one or more text to think, can be single-choice or multi-select

Usage

• Create: lb = ListBox (root object, [property list])
• Binding variable Var=stringvar () Lb=listbox (root object, listvariable = var)
• Get all the values in the list var.get ()
• Set all values in the list Var.set ((item1, item2, ...))
• Added: Lb.insert (item)
• Deleted: Lb.delete (item,...)
• Binding event Lb.bind (' <ButtonRelease-1> ', function)
• Get the selected option Lbl.get (Lb.curselection ())

Property

SelectMode can be MULTIPL single for Browse

Example

#-*-coding:cp936-*-from Tkinter Import *root = Tk () root.title ("Hello World") root.geometry () def print_item (event): 
   
    print Lb.get (Lb.curselection ())    var = stringvar () lb = Listbox (root,  listvariable = var) list_item = [1, 2, 3, 4]FO R item in List_item:    lb.insert (END, Item) Lb.delete (2, 4) Var.set ((' A ', ' ab ', ' C ', ' d ')) print var.get () lb.bind (' < Buttonrelease-1> ', Print_item) lb.pack ()    Root.mainloop ()
   

Effect

　　

7. Scrollbar

Description

Create a rectangular area on the screen to layout the form as a container

Usage

Frame (Root object, [property list]), the longest usage is to use with other controls.

Example

From Tkinter Import *root = Tk () root.title ("Hello World") root.geometry () def print_item (event):    print Lb.get ( Lb.curselection ())    var = stringvar () lb = Listbox (root, Height=5, selectmode=browse, listvariable = var) lb.bind (' <ButtonRelease-1> ', print_item) List_item = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]for item in List_item:    lb.insert (END, I TEM)    scrl = Scrollbar (root) scrl.pack (side=right, fill=y) lb.configure (Yscrollcommand = scrl.set) Lb.pack (side= Left, Fill=both) scrl[' command '] = Lb.yviewroot.mainloop ()
