Select all the values from a drag and drop Listbox in python

Question

I am trying to create a gui in tkinter where I will have a Listbox and be able to drag and drop files into it. How can I store all the items inside this listbox in a list with a command on the button?

lb = tk.Listbox(root, height=8)
lb.drop_target_register(DND_FILES)
lb.dnd_bind("<<Drop>>", lambda e: lb.insert(tk.END, e.data))
lb.grid(row=1, column=0, sticky="ew")

btn = ttk.Button(root, text="Submit")
btn.grid(row=2,column=0)

Answer 1

Without using button.

Try this:

from tkinter import *
from TkinterDnD2 import *

def path_listbox(event):
    listbox.insert("end", event.data)

window = TkinterDnD.Tk()
window.title('Delftstack')
window.geometry('400x300')
window.config(bg='gold')
frame = Frame(window)
frame.pack()

listbox = Listbox(
    frame,
    width=50,
    height=15,
    selectmode=SINGLE,
    )
listbox.pack(fill=X, side=LEFT)
listbox.drop_target_register(DND_FILES)
listbox.dnd_bind('<<Drop>>', path_listbox)

scrolbar= Scrollbar(
    frame,
    orient=VERTICAL
    )
scrolbar.pack(side=RIGHT, fill=Y)
# displays the content in listbox
listbox.configure(yscrollcommand=scrolbar.set)
# view the content vertically using scrollbar
scrolbar.config(command=listbox.yview)

window.mainloop()
