Python Tkinter grid_location()和grid_size()方法 _grid_size

本文概述

grid_location()方法–
grid_size()方法–

Tkinter用于开发GUI(图形用户界面)应用程序。它支持各种小部件以及各种小部件方法或通用小部件方法。
grid_location()方法– 此方法返回一个包含(列, 行)任何指定小部件的元组。由于此方法是窗口小部件方法, 因此无法将其与主对象一起使用(或Tk()目的)。为了使用此方法, 你首先应创建一个帧并将其视为父母(或主人)。

语法：widget.grid_location(x, y)参数：x和y是相对于小部件(父小部件)左上角的位置。

在下面的示例中, grid_location()用于获取小部件在帧小部件。

# This imports all functions in tkinter module from tkinter import * from tkinter.ttk import *# creating master window master = Tk()# This method is used to get the position # of the desired widget available in any # othet widget def click(event):# Here retrieving the size of the parent # widget relative to master widget x = event.x_root - f.winfo_rootx() y = event.y_root - f.winfo_rooty()# Here grid_location() method is used to # retrieve the relative position on the # parent widget z = f.grid_location(x, y)# printing position print (z)# Frame widget, wil work as # parent for buttons widget f = Frame(master) f.pack()# Button widgets b = Button(f, text = "Button" ) b.grid(row = 2 , column = 3 )c = Button(f, text = "Button2" ) c.grid(row = 1 , column = 0 )# Here binding click method with mouse master.bind( "< Button-1> " , click)# infinite loop mainloop()

grid_size()方法– 此方法用于获取任何父窗口小部件中存在的网格总数。这是一种窗口小部件方法, 因此无法将其与主对象一起使用。一个必须创建一个帧小部件。

语法：(列, 行)= widget.grid_size()返回值：返回列和行(网格)的总数。

以下是Python代码-

# This imports all functions in tkinter module from tkinter import * from tkinter.ttk import *# creating master window master = Tk()# This method is used to get the size # of the desired widget i.e number of grids # available in the widget def grids(event):# Here, grid_size() method is used to get # the total number grids available in frame # widget x = f.grid_size()# printing (columns, rows) print (x)# Frame widget, will work as # parent for buttons widget f = Frame(master) f.pack()# Button widgets b = Button(f, text = "Button" ) b.grid(row = 1 , column = 2 )c = Button(f, text = "Button2" ) c.grid(row = 1 , column = 0 )# Here binding click method with mouse master.bind( "< Button-1> " , grids)# infinite loop mainloop()

输出如下：
每次单击鼠标按钮时, 它将返回相同的值, 直到未添加更多小部件或行数和列数未增加。
