Get the location and total number of grids in Tkinter

To get the location and total number of grids in a tkinter widget (like a Frame), you can use the grid_slaves() method and some grid-related methods such as grid_info().

Let's create a tutorial to demonstrate how to do this:

Get Location and Total Number of Grids in `tkinter` Tutorial:

1. Import Required Libraries:

import tkinter as tk

2. Initialize Main Application Window:

root = tk.Tk()
root.title("Grid Location Tutorial")

3. Create Widgets and Use Grid Layout:

frame = tk.Frame(root)
frame.pack(padx=20, pady=20)

for i in range(3):
    for j in range(3):
        btn = tk.Button(frame, text=f"Button {i*3+j+1}")
        btn.grid(row=i, column=j, padx=5, pady=5)

Here, we've added a 3x3 grid of buttons in a frame.

4. Function to Display Grid Information:

Now, let's create a function that displays the total number of grid locations and the location (row and column) of each grid.

def show_grid_info():
    grid_widgets = frame.grid_slaves()  # Get list of widgets in grid
    total_grids = len(grid_widgets)  # Get total number of grid locations
    print(f"Total grids: {total_grids}")
    
    for widget in grid_widgets:
        info = widget.grid_info()
        row, col = info["row"], info["column"]
        print(f"Widget {widget['text']} is at row {row}, column {col}")

show_info_button = tk.Button(root, text="Show Grid Info", command=show_grid_info)
show_info_button.pack(pady=20)

5. Mainloop to Run the Application:

root.mainloop()

Complete Code:

import tkinter as tk

def show_grid_info():
    grid_widgets = frame.grid_slaves()  # Get list of widgets in grid
    total_grids = len(grid_widgets)  # Get total number of grid locations
    print(f"Total grids: {total_grids}")
    
    for widget in grid_widgets:
        info = widget.grid_info()
        row, col = info["row"], info["column"]
        print(f"Widget {widget['text']} is at row {row}, column {col}")

root = tk.Tk()
root.title("Grid Location Tutorial")

frame = tk.Frame(root)
frame.pack(padx=20, pady=20)

for i in range(3):
    for j in range(3):
        btn = tk.Button(frame, text=f"Button {i*3+j+1}")
        btn.grid(row=i, column=j, padx=5, pady=5)

show_info_button = tk.Button(root, text="Show Grid Info", command=show_grid_info)
show_info_button.pack(pady=20)

root.mainloop()

Run the provided code. Once you click the "Show Grid Info" button, it will print the total number of grids in the frame and the location (row and column) of each button in the console.

How to find the grid coordinates of a widget in Tkinter:

Description: You can find the grid coordinates of a widget in Tkinter by using the grid_info() method.

Code:

import tkinter as tk

def get_coordinates(widget):
    info = widget.grid_info()
    return info['row'], info['column']

root = tk.Tk()

# Create widgets in a grid layout
label1 = tk.Label(root, text="Widget 1")
label2 = tk.Label(root, text="Widget 2")
button = tk.Button(root, text="Click Me")

label1.grid(row=0, column=0)
label2.grid(row=1, column=1)
button.grid(row=2, column=2)

# Get coordinates of Widget 1
row, column = get_coordinates(label1)
print("Widget 1 coordinates:", f"Row: {row}, Column: {column}")

root.mainloop()

Finding the total number of rows and columns in Tkinter grid:

Description: You can find the total number of rows and columns in a Tkinter grid by using the grid_size() method.

Code:

import tkinter as tk

root = tk.Tk()

# Create widgets in a grid layout
label1 = tk.Label(root, text="Widget 1")
label2 = tk.Label(root, text="Widget 2")
button = tk.Button(root, text="Click Me")

label1.grid(row=0, column=0)
label2.grid(row=1, column=1)
button.grid(row=2, column=2)

# Get total number of rows and columns in the grid
total_rows, total_columns = root.grid_size()
print("Total Rows:", total_rows)
print("Total Columns:", total_columns)

root.mainloop()

Locating widgets within the Tkinter grid:

Description: The grid() method in Tkinter allows you to locate and adjust the position of widgets within the grid layout.

Code:

import tkinter as tk

root = tk.Tk()

# Create widgets in a grid layout
label1 = tk.Label(root, text="Widget 1")
label2 = tk.Label(root, text="Widget 2")
button = tk.Button(root, text="Click Me")

# Place widgets in specific grid locations
label1.grid(row=0, column=0)
label2.grid(row=1, column=1)
button.grid(row=2, column=2)

# Move Widget 2 to a different location
label2.grid(row=0, column=1)

root.mainloop()
