Python Tkinter | grid_location() and grid_size() method

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

# 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, will 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() 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

# 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()

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.
