PanedWindow Widget in Tkinter

The PanedWindow widget in tkinter is a container widget that can contain one or more child widgets. Its primary feature is that it provides a handle (or "sash") that users can drag to adjust the relative sizes of the child widgets. This makes it useful for creating resizable panes in a GUI application.

PanedWindow Widget in tkinter Tutorial:

1. Import Required Libraries:

import tkinter as tk
from tkinter import ttk

2. Create the Main Application Window:

root = tk.Tk()
root.title("PanedWindow Example")

3. Creating a PanedWindow:

The PanedWindow can be oriented either horizontally (tk.HORIZONTAL) or vertically (tk.VERTICAL).

# Creating a vertical PanedWindow
pane = tk.PanedWindow(root, orient=tk.VERTICAL)
pane.pack(fill=tk.BOTH, expand=1)

4. Adding Widgets to the PanedWindow:

# First child: A Text widget
text1 = tk.Text(pane, height=5, bg="lightgray")
pane.add(text1)

# Second child: Another Text widget
text2 = tk.Text(pane, height=5, bg="lightblue")
pane.add(text2)

You can add any widget to a PanedWindow, and it doesn't have to be just two. You can add as many as you'd like.

5. (Optional) Configuring the PanedWindow:

• sashrelief: Determines the relief style of the sash. Can be tk.RAISED, tk.SUNKEN, and so on.
• sashwidth: Determines the width of the sash.

pane.config(sashrelief=tk.RAISED, sashwidth=10)

6. Run the Main Loop:

root.mainloop()

Complete Code:

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.title("PanedWindow Example")

# Creating a vertical PanedWindow
pane = tk.PanedWindow(root, orient=tk.VERTICAL)
pane.pack(fill=tk.BOTH, expand=1)

# First child: A Text widget
text1 = tk.Text(pane, height=5, bg="lightgray")
pane.add(text1)

# Second child: Another Text widget
text2 = tk.Text(pane, height=5, bg="lightblue")
pane.add(text2)

# Configuring the PanedWindow
pane.config(sashrelief=tk.RAISED, sashwidth=10)

root.mainloop()

When you run the above code, you'll see a window with two Text widgets separated by a sash. You can click and drag the sash to adjust the relative sizes of the two Text widgets.

1. Python Tkinter create PanedWindow example:

The PanedWindow widget in Tkinter is used to create a container with panes that can be resized using a separator called a sash.

Example Code:

import tkinter as tk

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="horizontal")

frame1 = tk.Frame(paned_window, background="lightblue", width=100)
frame2 = tk.Frame(paned_window, background="lightgreen", width=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

root.mainloop()

2. How to use the PanedWindow widget in Tkinter:

The PanedWindow widget is used to create a container that can hold multiple panes. The panes can be arranged horizontally or vertically, and a separator (sash) allows users to resize the panes.

3. Tkinter PanedWindow options and configuration:

The PanedWindow widget has options like orient, sashwidth, sashrelief, and more for configuring its behavior. These options determine the orientation of the panes and appearance of the sash.

Example Code:

import tkinter as tk

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="vertical", sashwidth=8, sashrelief="raised")

frame1 = tk.Frame(paned_window, background="lightblue", height=100)
frame2 = tk.Frame(paned_window, background="lightgreen", height=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

root.mainloop()

4. Creating resizable panes in Tkinter:

The PanedWindow widget enables the creation of resizable panes. Users can drag the sash to adjust the size of the panes dynamically.

Example Code:

import tkinter as tk

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="horizontal")

frame1 = tk.Frame(paned_window, background="lightblue", width=100)
frame2 = tk.Frame(paned_window, background="lightgreen", width=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

root.mainloop()

5. Python Tkinter PanedWindow sash positions:

The position of the sash in a PanedWindow can be set or retrieved using the sashposition() method. This allows you to programmatically control the initial position of the sash.

Example Code:

import tkinter as tk

def move_sash():
    paned_window.sash_position(0, 150)  # Set the position of the sash for the first pane

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="horizontal")

frame1 = tk.Frame(paned_window, background="lightblue", width=100)
frame2 = tk.Frame(paned_window, background="lightgreen", width=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

move_button = tk.Button(root, text="Move Sash", command=move_sash)
move_button.pack()

root.mainloop()

6. Customizing PanedWindow appearance in Tkinter:

The appearance of the PanedWindow can be customized by setting options like sashwidth, sashrelief, and configuring the panes with background colors, sizes, etc.

Example Code:

import tkinter as tk

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="horizontal", sashwidth=8, sashrelief="raised")

frame1 = tk.Frame(paned_window, background="lightblue", width=100)
frame2 = tk.Frame(paned_window, background="lightgreen", width=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

root.mainloop()

7. Managing resizable panes with PanedWindow:

The PanedWindow widget provides a simple way to manage resizable panes in Tkinter. Panes can be added or removed dynamically to create a flexible layout.

Example Code:

import tkinter as tk

root = tk.Tk()

paned_window = tk.PanedWindow(root, orient="horizontal")

frame1 = tk.Frame(paned_window, background="lightblue", width=100)
frame2 = tk.Frame(paned_window, background="lightgreen", width=100)

paned_window.add(frame1)
paned_window.add(frame2)

paned_window.pack(fill="both", expand=True)

def add_pane():
    new_frame = tk.Frame(paned_window, background="lightcoral", width=100)
    paned_window.add(new_frame)

add_button = tk.Button(root, text="Add Pane", command=add_pane)
add_button.pack()

root.mainloop()

8. Tkinter horizontal and vertical PanedWindow:

The PanedWindow can be configured to have either horizontal or vertical orientation. This allows you to create layouts with resizable panes in both directions.

Example Code:

import tkinter as tk

root = tk.Tk()

# Horizontal PanedWindow
paned_window_horizontal = tk.PanedWindow(root, orient="horizontal")
frame1 = tk.Frame(paned_window_horizontal, background="lightblue", width=100)
frame2 = tk.Frame(paned_window_horizontal, background="lightgreen", width=100)
paned_window_horizontal.add(frame1)
paned_window_horizontal.add(frame2)
paned_window_horizontal.pack(fill="both", expand=True)

# Vertical PanedWindow
paned_window_vertical = tk.PanedWindow(root, orient="vertical")
frame3 = tk.Frame(paned_window_vertical, background="lightcoral", height=100)
frame4 = tk.Frame(paned_window_vertical, background="lightyellow", height=100)
paned_window_vertical.add(frame3)
paned_window_vertical.add(frame4)
paned_window_vertical.pack(fill="both", expand=True)

root.mainloop()
