How To Create GUI Layouts With Python Tkinter Separator?

In this tutorial, I will explain how to create GUI layouts with Python Tkinter Separator. As a developer, I often faced the challenge of designing GUI layouts. Then I explored more about this topic and I will share my findings with suitable examples and screenshots of executed example code.

Tkinter Separator Widget in Python

The Tkinter Separator widget is a thin horizontal or vertical line that helps divide and group related widgets in a GUI layout. It is part of the ttk module in Tkinter, which provides themed widgets for a modern and consistent look across different platforms. By using separators, we can make our GUI designs more attractive and intuitive for users.

Create a Horizontal Separator

To create a horizontal separator, we can use the ttk.Separator widget with the orient parameter set to "horizontal". Here’s an example:

from tkinter import *
from tkinter import ttk

root = Tk()
root.title("Employee Management System")

# Create a horizontal separator
separator = ttk.Separator(root, orient="horizontal")
separator.pack(fill="x", pady=40)

# Add widgets above and below the separator
label_above = Label(root, text="Employee Details")
label_above.pack()

separator.pack()

label_below = Label(root, text="Contact Information")
label_below.pack()

root.mainloop()

You can see the output in the screenshot below.

Create GUI Layouts with Python Tkinter Separator

In this example, we create a simple GUI for an employee management system in the USA. We use a horizontal separator to visually divide the employee details section from the contact information section. The separator is created ttk.Separator(root, orient=”horizontal”) and is packed fill="x" to stretch it horizontally across the window. We add padding (pady=10) to create some space around the separator.

Create a Vertical Separator

Similarly, we can create a vertical separator by setting the orient parameter to "vertical". Here’s an example:

from tkinter import *
from tkinter import ttk

root = Tk()
root.title("Sales Dashboard")

# Create a vertical separator
separator = ttk.Separator(root, orient="vertical")
separator.pack(side="left", fill="y", padx=40)

# Add widgets on the left and right of the separator
left_frame = Frame(root)
left_frame.pack(side="left")

label_left = Label(left_frame, text="Product Categories")
label_left.pack()

right_frame = Frame(root)
right_frame.pack(side="right")

label_right = Label(right_frame, text="Sales Report")
label_right.pack()

root.mainloop()

You can see the output in the screenshot below.

How to Create GUI Layouts with Python Tkinter Separator

In this example, we create a sales dashboard GUI with a vertical separator. The separator is created using ttk.Separator(root, orient="vertical") and is packed to the left side of the window with side="left" and fill="y" to stretch it vertically. We add horizontal padding (padx=10) to create space around the separator.

Combine Horizontal and Vertical Separators

We can combine horizontal and vertical separators to create more complex and visually appealing GUI layouts. Here’s an example:

from tkinter import *
from tkinter import ttk

root = Tk()
root.title("Customer Relationship Management")

# Create a horizontal separator
separator_h = ttk.Separator(root, orient="horizontal")
separator_h.grid(row=1, column=0, columnspan=3, sticky="ew", pady=10)

# Create vertical separators
separator_v1 = ttk.Separator(root, orient="vertical")
separator_v1.grid(row=0, column=1, rowspan=3, sticky="ns", padx=10)

separator_v2 = ttk.Separator(root, orient="vertical")
separator_v2.grid(row=0, column=3, rowspan=3, sticky="ns", padx=10)

# Add widgets in the grid layout
label_customer = Label(root, text="Customer Details")
label_customer.grid(row=0, column=0, padx=10, pady=10)

label_interactions = Label(root, text="Customer Interactions")
label_interactions.grid(row=0, column=2, padx=10, pady=10)

label_notes = Label(root, text="Notes")
label_notes.grid(row=2, column=0, padx=10, pady=10)

label_timeline = Label(root, text="Timeline")
label_timeline.grid(row=2, column=2, padx=10, pady=10)

root.mainloop()

You can see the output in the screenshot below.

Create GUI Layouts with Python Tkinter Separator Combine Horizontal and Vertical

In this example, we create a customer relationship management (CRM) GUI using a combination of horizontal and vertical separators. We use the grid layout manager to arrange the widgets in a tabular structure.

The horizontal separator (separator_h) is placed in row 1 and spans across all columns using columnspan=3. It stretches horizontally with sticky="ew".
The vertical separators (separator_v1 and separator_v2) are placed in columns 1 and 3, respectively, and span across all rows using rowspan=3. They stretch vertically with sticky="ns".

Separator Color

Python Tkinter Separator provides an option style using which we can change the color of the separator line.

from tkinter import *
from tkinter import ttk

root = Tk()
root.title("Customer Relationship Management")
root.geometry("500x300")

# Create a horizontal colored separator
separator_h = Frame(root, height=2, bg="red")  # Change color here
separator_h.grid(row=1, column=0, columnspan=3, sticky="ew", pady=10)

# Create vertical colored separators
separator_v1 = Frame(root, width=2, bg="green")  # Change color here
separator_v1.grid(row=0, column=1, rowspan=3, sticky="ns", padx=10)

separator_v2 = Frame(root, width=2, bg="blue")  # Change color here
separator_v2.grid(row=0, column=3, rowspan=3, sticky="ns", padx=10)

label_customer = Label(root, text="Customer Details")
label_customer.grid(row=0, column=0, padx=10, pady=10)

label_interactions = Label(root, text="Customer Interactions")
label_interactions.grid(row=0, column=2, padx=10, pady=10)

label_notes = Label(root, text="Notes")
label_notes.grid(row=2, column=0, padx=10, pady=10)

label_timeline = Label(root, text="Timeline")
label_timeline.grid(row=2, column=2, padx=10, pady=10)

root.mainloop()

You can see the output in the screenshot below.

Best Practices for Using Tkinter Separators

When using Tkinter separators in your GUI layouts, consider the following best practices:

Use separators sparingly and only when necessary to avoid cluttering the interface.
Choose the appropriate orientation (horizontal or vertical) based on the layout requirements.
Adjust the padding around separators to create proper spacing and visual balance.
Combine separators with appropriate layout managers (pack, grid, or place) to achieve the desired layout.
Maintain consistency in separator usage throughout your GUI for a cohesive look and feel.

Conclusion

In this tutorial, I helped you learn how to create GUI layouts with Python Tkinter Separator. I discussed how to create a horizontal separator , a vertical separator and we combined both horizontal and vertical separators. I also discussed how to apply color to a separator and some best practices for using Tkinter separator.
