Python PanedWindow

The PanedWindow widget in Python is a container widget that is used to organize the layout of other widgets within a window. A PanedWindow is a horizontal or vertical pane that contains two or more subpanes or widgets, separated by divider lines or "sashes". These sashes can be dragged by the user to adjust the size of each pane or widget.

Syntax

w = PanedWindow(master, **options)

Example

from tkinter import *

root = Tk()
root.geometry("500x500")

paned_window = PanedWindow(root)
paned_window.pack(fill=BOTH, expand=True)

frame1 = Frame(paned_window, bd=1, relief=SUNKEN, bg="red")
paned_window.add(frame1)

frame2 = Frame(paned_window, bd=1, relief=SUNKEN, bg="blue")
paned_window.add(frame2)

root.mainloop()

Output

The above example will create a window with a PanedWindow widget that has two subpanes (frames) in it - one with a red background and one with a blue background - separated by a divider line.

Explanation

• In the above example, we first import the tkinter module.
• Then, we create a root window with a size of 500x500 pixels using the geometry() method.
• We create a PanedWindow widget with the PanedWindow() method and pack it into the root window using the pack() method with fill=BOTH and expand=True parameters.
• We create two Frame widgets as subpanes for the PanedWindow widget, one with a red background and one with a blue background. We add these frames to the PanedWindow widget using the add() method.
• Finally, we enter the main loop using the mainloop() method, which runs the application until the window is closed.

Use

The PanedWindow widget in Python is primarily used for organizing the widgets within a window. It can be used to create complex layouts in which the user can adjust the size of different panes and widgets to suit their preferences or needs. This widget is useful for creating applications such as text editors, IDEs, file managers, and other types of applications that require a flexible layout.

• The add() method is used to add subpanes or widgets to the PanedWindow.

Summary

In this tutorial, we learned about the PanedWindow widget in Python, its syntax, different parameters used in the syntax, how to create a PanedWindow widget, its important methods, and a few important points to keep in mind while working with this widget. We also went over a code example to illustrate the usage of this widget in a practical scenario.
