Set the dimensions of the Tkinter window

Setting the dimensions (i.e., width and height) of a tkinter window is fundamental when you want to control the initial size of your application. You may also want to position the window at a specific location on the screen.

Here's a tutorial on how to set the dimensions and position of a tkinter window:

Setting Dimensions of the Tkinter Window Tutorial:

1. Import Required Libraries:

import tkinter as tk

2. Create the Main Application Window:

root = tk.Tk()
root.title("Window Dimensions")

3. Set Window Size: You can set the window size using the geometry() method of the window. The format is "widthxheight".

For example, to set the width to 300 pixels and height to 200 pixels:

root.geometry("300x200")

4. Set Window Position: If you also want to control where the window appears on the screen, you can extend the geometry string to "widthxheight+x+y". The "x" and "y" values determine the top-left corner's position of the window relative to the screen.

For instance, to place the window 100 pixels from the left edge and 50 pixels from the top:

root.geometry("300x200+100+50")

5. Keep Window Size Fixed (Optional): If you want to prevent the user from resizing the window, you can use the resizable() method. The two arguments to this method determine whether the window can be resized horizontally and vertically.

For a completely non-resizable window:

root.resizable(False, False)

6. Run the Main Loop:

root.mainloop()

Complete Code:

import tkinter as tk

root = tk.Tk()
root.title("Window Dimensions")

root.geometry("300x200+100+50")

root.resizable(False, False)

root.mainloop()

After running the complete code, you'll get a window with the specified dimensions and position, and the user won't be able to resize it. Adjust the numbers in the geometry() method as needed to fit your specific requirements.

Python Tkinter window size example: In Tkinter, you can set the initial size of a window using the geometry() method.

import tkinter as tk

root = tk.Tk()

# Set window size to 400x300 pixels
root.geometry("400x300")

root.mainloop()

Setting window dimensions in Tkinter: Use the geometry() method to set the initial dimensions of a Tkinter window.

import tkinter as tk

root = tk.Tk()

# Set window size to 400x300 pixels
root.geometry("400x300")

root.mainloop()

How to resize Tkinter window: You can dynamically resize a Tkinter window by using the geometry() method and updating the dimensions.

import tkinter as tk

def resize_window():
    root.geometry("500x400")

root = tk.Tk()

# Set initial window size
root.geometry("400x300")

# Button to resize the window
resize_button = tk.Button(root, text="Resize Window", command=resize_window)
resize_button.pack()

root.mainloop()

Changing window size in Tkinter: Adjust the window size by calling the geometry() method with the desired dimensions.

import tkinter as tk

def resize_window():
    root.geometry("500x400")

root = tk.Tk()

# Set initial window size
root.geometry("400x300")

# Button to resize the window
resize_button = tk.Button(root, text="Resize Window", command=resize_window)
resize_button.pack()

root.mainloop()

Setting width and height of Tkinter window: You can set the width and height of a Tkinter window by specifying them in the geometry() method.
```
import tkinter as tk

root = tk.Tk()

# Set window width to 500 and height to 400 pixels
root.geometry("500x400")

root.mainloop()
```

Python Tkinter resize window programmatically: Programmatically resize the Tkinter window by updating the dimensions with the geometry() method.

import tkinter as tk

def resize_window():
    root.geometry("500x400")

root = tk.Tk()

# Set initial window size
root.geometry("400x300")

# Button to resize the window
resize_button = tk.Button(root, text="Resize Window", command=resize_window)
resize_button.pack()

root.mainloop()

Adjusting Tkinter window dimensions: Adjust the dimensions of a Tkinter window by calling the geometry() method with the desired width and height.
```
import tkinter as tk

root = tk.Tk()

# Set window width to 500 and height to 400 pixels
root.geometry("500x400")

root.mainloop()
```
