Last Updated :

Tkinter is used to develop GUI (Graphical User Interface) applications. It supports a variety of widgets as well as a variety of widgets methods or universal widget methods.
grid_location() method –
This method returns a tuple containing (column, row) of any specified widget. Since this method is a widget method you cannot use it with master object ( or Tk() object). In order to use this method, you should first create a Frame and treat it as a parent (or master).
Syntax: widget.grid_location(x, y)
Parameters:
x and y are the positions, relative to the upper left corner of the widget (parent widget).
In below example, grid_location() is used to get the location of the widget in the Frame widget.
Python3
from tkinter import * from tkinter.ttk import *
master = Tk()
def click(event):
x = event.x_root - f.winfo_rootx()
y = event.y_root - f.winfo_rooty()
z = f.grid_location(x, y)
print (z)
f = Frame(master)
f.pack()
b = Button(f, text = "Button" )
b.grid(row = 2 , column = 3 )
c = Button(f, text = "Button2" )
c.grid(row = 1 , column = 0 )
master.bind( "<Button-1>" , click)
mainloop()

grid_size() method –
This method is used to get the total number of grids present in any parent widget. This is a widget method so one cannot use it with master object. One has to create a Frame widget.
Syntax: (columns, rows) = widget.grid_size()
Return Value: It returns total numbers of columns and rows (grids).
Below is the Python code-
Python3
from tkinter import * from tkinter.ttk import *
master = Tk()
def grids(event):
x = f.grid_size()
print (x)
f = Frame(master)
f.pack()
b = Button(f, text = "Button" )
b.grid(row = 1 , column = 2 )
c = Button(f, text = "Button2" )
c.grid(row = 1 , column = 0 )
master.bind( "<Button-1>" , grids)
mainloop()
|
Output:
Every time you click the mouse button it will return the same value until more widgets are not added OR number of rows and columns are not increased.
