modify Button attribute

python tkinter Of Button Components

Tkinter There are three ways to lay out

python tkinter Button Button Use Create and set up windows

from tkinter import *# Create window objects root = Tk()# Window property settings root.title (' Window title ')root.geometry('300x400')root.configure(bg='blue')root.iconbitmap(r'C:\Users\Administrator\Desktop\iVista 2 OS X Icons ico\ico\Burn.ico')

Mark： With windows iconbitmap Function changes the icon .

Button Button attribute 1

def print1(): print(' Hello ')button = Button(root,text=' Print ', font=(' Regular script ',20),fg='red',bg='black', anchor='center',command=print1, #command It means command height=1,width=5,bd=6)button.pack()root.mainloop()

Effect diagram

Mark：Button Many properties of buttons and Label Similar labels .

For example, the text (text)、 Text Fonts (font)、 font size 、 Color (fg)、 The text is in Button Position in the button (anchor)、 Alignment of different lines of text (justify)、 The height and width of the button (height、width)、 The background color of the button (bg) wait . and Lable The label compares ,Button The button has a callback function ,command= Function name , When the button is clicked , Will execute the code block of the callback function .

Button Button attribute 2

def hello(): print(' Hello ')im = PhotoImage(file=r'C:\Users\Administrator\Desktop\ picture PNG Format \ Magpie peach blossom folding fan .png')button = Button(root,text='button',command = hello, height=500,width=500,image=im, relief= SUNKEN)button.pack()root.mainloop()

Effect diagram

Mark： It can also be in Button A picture is displayed on the button .

First convert the picture you want to display into image object (PhotoImage(file=‘ Picture path ’)), And then use image attribute ,image=image object . If you do not set the height and width of the button (height,width), Then the size of the display button is the size of the image . If you set the height and width of the button , Only a part of the picture will be displayed . here ,height、width The unit of is the pixel unit .

modify Button attribute

Dynamic modification button Button Properties of

def print1(): #button['text']='Now you see me' button.configure(text='Now you see me')button = Button(root,text=' Print ', font=(' Regular script ',30),fg='red',bg='black', anchor='center',command=print1, height=1,width=20,bd=6)button.pack()root.mainloop()

Effect diagram

Click on Button After button , The text content becomes

Mark：Button Properties can be modified .

If the effect you want to render is already set Button After clicking the button, the attribute changes , It can be modified in the callback function Button Properties of ：Button object [‘ The key parameters ’]= The value to modify or Button object .comfigure( The key parameters = Value to modify ).

Summary ： adopt Button object , We can set buttons with different appearance in the window . and , Click on Button Button , You can execute code blocks in functions .

python tkinter Of Button Components

This place is not very difficult , Just remember the parameters .

Tkinter There are three ways to lay out Geometric methods describe pack() packing ;grid() grid ;place() Location ;

The code is as follows ：

# coding:utf8import tkinter as tkclass APP: def __init__(self, master): frame = tk.Frame(master) frame.pack(side=tk.RIGHT, padx=70, pady=100) b4 = tk.Button(frame, text=" test command Click to call the function ", bd="4", bg="yellow", command=lambda: self.Newtk("x")) b4.pack() @staticmethod def Newtk(x): if x != "x": return 0 win1 = tk.Tk() win1.title(" Prompt information ") frame1 = tk.Frame(win1) frame1.pack(side=tk.RIGHT, padx=70, pady=100) l1 = tk.Label(frame1, text=" Oh , You click on the . Play a box for you ") l1.pack()admin = tk.Tk()admin.title(" test Button")win = APP(admin)admin.mainloop()

w = Button ( master, option=value, ... ) Sn optional & describe 1

activebackground

When the mouse is up , The background color of the button

activeforeground

When the mouse is up , The foreground color of the button

The size of the button border , The default is 2 Pixel

The background color of the button

command

The function associated with the button , When the button is clicked , Execute this function

The foreground color of the button （ The color of the button text ）

font

Text Fonts

height

The height of the button

highlightcolor

The color to highlight

image

The picture to be displayed on the button

justify

When displaying multiple lines of text , Set the alignment between different rows , Options include LEFT, RIGHT, CENTER

padx

Button x The inner margin in the axis direction (padding), It refers to the distance between the button content and the button edge

pady

Button y The inner margin in the axis direction (padding)

relief

Border style , Setting controls 3D effect , Optional ：FLAT、SUNKEN、RAISED、GROOVE、RIDGE. The default is FLAT.

state

Set button component status , Optional NORMAL、ACTIVE、 DISABLED. Default NORMAL.

underline

Underline . The text on the default button is not underlined . The value is the underlined string index , by 0 when , The first character is underlined , by 1 when , The first two characters are underlined , And so on

width

The width of the button , If this item is not set , Its size to fit the contents of the button （ Size of text or picture ）

wraplength

Limit the number of characters displayed on each line of the button

text

The text content of the button

anchor

Anchor options , Controls the position of the text , The default is center

The above is personal experience , I hope I can give you a reference , I also hope you can support the software development network .
