Tkinter 中的 Python | grid()方法
原文:https://www . geesforgeks . org/python-grid-method-in-tkinter/
网格几何管理器将小部件放在二维表格中。主小部件被分成许多行和列，结果表中的每个“单元格”可以容纳一个小部件。 格子经理是Tkit中最灵活的几何经理。如果你不想学习如何以及何时使用这三个经理，你至少应该确保学习这一个。
考虑以下示例–
使用 pack 管理器创建这个布局是可能的，但是它需要大量额外的框架小部件，并且需要大量的工作来使事情看起来更好。如果改为使用网格管理器，每个小部件只需要一次调用就可以让一切都布局好。
使用网格管理器很容易。只需创建小部件，并使用网格方法告诉管理人员将它们放置在哪个行和列中。您不必事先指定网格的大小；管理器会根据其中的小部件自动确定这一点。
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()
输出:
代码#2: 创建如上图所示的布局。
# 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()
输出:
警告:不要将格()和包()混在同一个主窗口。
