Python Tkinter | grid_location() 和 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任何指定小部件的 (column, row) 的元组。由于此方法是一个小部件方法，因此您不能将其与主对象（或 Tk() 对象）一起使用。为了使用此方法，您应该首先创建一个 Frame 并将其视为父级（或主控）。

Syntax: widget.grid_location(x, y)
Parameters: 
x and y are the positions, relative to the upper left corner of the widget (parent widget). 
 

在下面的示例中，grid_location() 用于获取框架小部件中小部件的位置。

Python3

# 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
# other 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("", 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。这是一种小部件方法，因此不能将其与主对象一起使用。必须创建一个 Frame 小部件。

Syntax: (columns, rows) = widget.grid_size()
Return Value: It returns total numbers of columns and rows (grids). 
 

下面是Python代码——

Python3

# 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("", grids)
 
# infinite loop
mainloop()

输出：
每次单击鼠标按钮时，它将返回相同的值，直到不添加更多小部件或不增加行数和列数。
