What is correct: widget.rowconfigure or widget.grid_rowconfigure in Tkinter?

When working with Tkinter's Grid geometry manager, you'll encounter two similar methods: widget.rowconfigure() and widget.grid_rowconfigure(). Both methods configure how rows behave in the grid layout, particularly for weight distribution and resizing behavior.

The Answer: Both Are Correct

widget.rowconfigure() and widget.grid_rowconfigure() are identical methods. The rowconfigure() method is simply an alias for grid_rowconfigure(). You can use either one − they produce exactly the same result.

Syntax

widget.rowconfigure(row_index, weight=value)
# OR
widget.grid_rowconfigure(row_index, weight=value)

Parameters

• row_index: The row number to configure (starting from 0)
• weight: How much extra space this row should take when the window is resized (default is 0)
• minsize: Minimum size of the row in pixels
• pad: Extra padding around the row

Example

Here's a practical example showing both methods work identically ?

import tkinter as tk

# Create main window
root = tk.Tk()
root.geometry("400x300")
root.title("Row Configure Example")

# Create two frames
frame1 = tk.Frame(root, bg="lightblue", height=100)
frame2 = tk.Frame(root, bg="lightgreen", height=100)

# Place frames in grid
frame1.grid(row=0, column=0, sticky="ew", padx=5, pady=5)
frame2.grid(row=1, column=0, sticky="ew", padx=5, pady=5)

# Using rowconfigure (shorter alias)
root.rowconfigure(0, weight=1)
# Using grid_rowconfigure (full method name)
root.grid_rowconfigure(1, weight=2)

# Configure column to expand horizontally
root.columnconfigure(0, weight=1)

root.mainloop()

In this example, row 1 (frame2) gets twice the extra space compared to row 0 (frame1) when you resize the window vertically.

Common Use Cases

Best Practice

Most developers prefer the shorter rowconfigure() method for cleaner code. The full grid_rowconfigure() name can be useful when you want to be explicit about using the grid manager.

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

# Create a text widget that should expand
text = tk.Text(root)
text.grid(row=0, column=0, sticky="nsew")

# Make the text widget expand with window
root.rowconfigure(0, weight=1)    # Preferred: shorter
root.columnconfigure(0, weight=1) # Preferred: shorter

root.mainloop()

Conclusion

Both rowconfigure() and grid_rowconfigure() are correct and identical methods. Use rowconfigure() for cleaner code, or grid_rowconfigure() for explicit clarity about the geometry manager being used.
