Python Tkinter | grid_location() and grid_size() method (original) (raw)
Last Updated : 21 Jun, 2022
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("", 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("", 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.
