In python you can use the following method to get the selected element in lisxtbox component.
A listbox shows a list of options. You can then click on any of those options. By default it won’t do anything, but you can link that to a callback function or link a button click.
Output:
python listbox element click

# -*- coding: utf-8 -*- import tkinter as tk def getElement(event): selection = event.widget.curselection() index = selection[0] value = event.widget.get(index) result.set(value) print(index,' -> ',value) root = tk.Tk() root.title("Code4Example.com") # Add a title result =tk.StringVar() tk.Label(root,text="""Click Listbox Element""").grid(row = 0, column = 0) tk.Label(root,text="""result""", textvariable=result).grid(row = 1, column = 0) var2 = tk.StringVar() var2.set(('Apple','Banana','Pear', 'Peach')) lb = tk.Listbox(root, listvariable=var2) lb.grid(row = 0, column = 1) lb.bind('<<ListboxSelect>>', getElement) #Select click root.mainloop() |
Example 2:Select listbox element by double click
