Python | PanedWindow Widget in Tkinter

Last Updated : 07 Jun, 2019

Tkinter supports a variety of widgets to make GUI more and more attractive and functional. The

PanedWindow

widget is a geometry manager widget, which can contain one or more child widgets

panes

. The child widgets can be resized by the user, by moving separator lines

sashes

using the mouse.

Syntax: PanedWindow(master, **options) Parameters: master: parent widget or main Tk() object options: which are passed in config method or directly in the constructor

PanedWindow can be used to implement common 2-panes or 3-panes but multiple panes can be used.

Code #1:

PanedWindow with only two panes

Python3 1==


 # Importing everything from tkinter module
from tkinter import * from tkinter import ttk

# main tkinter window
root = Tk()

# panedwindow object
pw = PanedWindow(orient ='vertical')

# Button widget
top = ttk.Button(pw, text ="Click Me !\nI'm a Button")
top.pack(side = TOP)

# This will add button widget to the panedwindow
pw.add(top)

# Checkbutton Widget
bot = Checkbutton(pw, text ="Choose Me !")
bot.pack(side = TOP)

# This will add Checkbutton to panedwindow
pw.add(bot)

# expand is used so that widgets can expand
# fill is used to let widgets adjust itself
# according to the size of main window
pw.pack(fill = BOTH, expand = True)

# This method is used to show sash
pw.configure(sashrelief = RAISED)

# Infinite loop can be destroyed by
# keyboard or mouse interrupt
mainloop()

Output: Code #2:

PanedWindow with multiple panes

Python3 1==


 # Importing everything from tkinter module
from tkinter import * from tkinter import ttk

# main tkinter window
root = Tk()

# panedwindow object
pw = PanedWindow(orient ='vertical')

# Button widget
top = ttk.Button(pw, text ="Click Me !\nI'm a Button")
top.pack(side = TOP)

# This will add button widget to the panedwindow
pw.add(top)

# Checkbutton Widget
bot = Checkbutton(pw, text ="Choose Me !")
bot.pack(side = TOP)

# This will add Checkbutton to panedwindow
pw.add(bot)

# adding Label widget
label = Label(pw, text ="I'm a Label")
label.pack(side = TOP)

pw.add(label)

# Tkinter string variable
string = StringVar()

# Entry widget with some styling in fonts
entry = Entry(pw, textvariable = string, font =('arial', 15, 'bold'))
entry.pack()

# Focus force is used to focus on particular
# widget that means widget is already selected for operations
entry.focus_force()

pw.add(entry)

# expand is used so that widgets can expand
# fill is used to let widgets adjust itself
# according to the size of main window
pw.pack(fill = BOTH, expand = True)

# This method is used to show sash
pw.configure(sashrelief = RAISED)

# Infinite loop can be destroyed by
# keyboard or mouse interrupt
mainloop()
