Python Tkinter中的grid()方法用法示例 _GUI

Grid几何图形管理器将小部件放在一个二维表中。主小部件被分成若干行和列，结果表中的每个“单元格”都可以包含一个小部件。
网格管理器是Tkinter中最灵活的几何管理器。如果你不想学习如何以及何时使用这三种管理方式，你至少应该学习这一种。
考虑以下示例–

使用包管理器是可能的, 但是它需要大量额外的框架小部件, 并且需要做很多工作才能使外观看起来更好。如果改为使用网格管理器, 则每个小部件只需要调用一次即可正确布置所有内容。
【Python Tkinter中的grid()方法用法示例】使用网格管理器很容易。只需创建小部件，并使用grid方法告诉管理器将它们放在哪一行和哪一列中。你不必预先指定网格的大小; 管理器从其中的小部件自动确定。
代码1：

# import tkinter module from tkinter import * from tkinter.ttk import *# creating main tkinter window/toplevel master = Tk()# this wil create a label widget l1 = Label(master, text = "First:" ) l2 = Label(master, text = "Second:" )# grid method to arrange labels in respective # rows and columns as specified l1.grid(row = 0 , column = 0 , sticky = W, pady = 2 ) l2.grid(row = 1 , column = 0 , sticky = W, pady = 2 )# entry widgets, used to take entry from user e1 = Entry(master) e2 = Entry(master)# this will arrange entry widgets e1.grid(row = 0 , column = 1 , pady = 2 ) e2.grid(row = 1 , column = 1 , pady = 2 )# infinite loop which can be terminated by keyboard # or mouse interrupt mainloop()

创建上面显示的布局。

# import tkinter module from tkinter import * from tkinter.ttk import *# creating main tkinter window/toplevel master = Tk()# this will create a label widget l1 = Label(master, text = "Height" ) l2 = Label(master, text = "Width" )# grid method to arrange labels in respective # rows and columns as specified l1.grid(row = 0 , column = 0 , sticky = W, pady = 2 ) l2.grid(row = 1 , column = 0 , sticky = W, pady = 2 )# entry widgets, used to take entry from user e1 = Entry(master) e2 = Entry(master)# this will arrange entry widgets e1.grid(row = 0 , column = 1 , pady = 2 ) e2.grid(row = 1 , column = 1 , pady = 2 )# checkbutton widget c1 = Checkbutton(master, text = "Preserve" ) c1.grid(row = 2 , column = 0 , sticky = W, columnspan = 2 )# adding image (remember image should be PNG and not JPG) img = PhotoImage( file = r "C:\Users\Admin\Pictures\capture1.png" ) img1 = img.subsample( 2 , 2 )# setting image with the help of label Label(master, image = img1).grid(row = 0 , column = 2 , columnspan = 2 , rowspan = 2 , padx = 5 , pady = 5 )# button widget b1 = Button(master, text = "Zoom in" ) b2 = Button(master, text = "Zoom out" )# arranging button widgets b1.grid(row = 2 , column = 2 , sticky = E) b2.grid(row = 2 , column = 3 , sticky = E)# infinite loop which can be terminated # by keyboard or mouse interrupt mainloop()
