I using tkinter and tkinterdnd2 to make a drag and drop GUI (I am using the below code). How do I return the value of the path name to use later? When I try to print(get_path) it returns this <function get_path at 0x10cfa10d0> or if I set a global varible = event I get <tkinterdnd2.TkinterDnD.DnDEvent object at 0x164cef0d0>
def get_path(event):
pathLabel.configure(text=event.data)
root = TkinterDnD.Tk()
root.geometry("350x100")
root.title("Get file path")
nameVar = StringVar()
entryWidget = Entry(root)
entryWidget.pack(side=TOP, padx=5, pady=5)
pathLabel = Label(root, text="Drag and drop file in the entry box")
pathLabel.pack(side=TOP)
entryWidget.drop_target_register(DND_ALL)
entryWidget.dnd_bind("<<Drop>>", get_path)
Button(root, text="Close", command=root.destroy).pack()
root.mainloop()

I am attempting to open a new window when the New Window button is pressed in the main "root" window. This currently works and does indeed open a second window. In the second window I want to ask the user for an input and then this input will be turned into a list of strings.
An example input would be "Amy, Bob, Carl". The expected output would be ['Amy', 'Bob', 'Carl'] but currently the program just returns [''].
My current code is:
from tkinter import *
root = Tk()
root.title("Welcome screen")
root.geometry("300x300")
def open_new_window():
top = Toplevel()
top.title("second window")
entities = Entry(top)
entries = entities.get().split(", ")
entities.pack()
entities.focus_set()
print(entries)
sub_button = Button(top, text="Submit", command= ?)
sub_button.pack(pady=20)
close_btn = Button(top, text="Close", command=top.destroy)
close_btn.pack()
open_button = Button(root, text="New Window", command=open_new_window)
open_button.pack(pady=20)
exit_button = Button(root, text="Close", command=root.destroy)
exit_button.pack(pady=20)
root.mainloop()
I am new to Tkinter and I am unsure why this is happening. I'm sure it's a simple silly mistake but I can't find where I am going wrong. I also am unsure as to whether I need a Submit button as I don't know what command should be passed to it.
Any advice is appreciated. Please let me know if any additional information is required.
First, we will understand why you got a empty list: your code is executed sequentially, so when you do the entities.get() you haven't yet written anything nor pressed "Submit", i.e., you want to read the entry box once you press the "Submit", not earlier, for that reason, you have the command = ?.
As I am aware, you have mainly 2 options:
Get the text from the button itself
Create a variable linked to the entry box and read this
Method 1: read the data from the entry
from tkinter import *
root = Tk()
root.title("Welcome screen")
root.geometry("300x300")
def do_stuff(entry):
print(entry.get())
def open_new_window():
top = Toplevel()
top.title("second window")
entities = Entry(top)
entities.pack()
entities.focus_set()
sub_button = Button(top, text="Submit", command= lambda: do_stuff(entities))
sub_button.pack(pady=20)
close_btn = Button(top, text="Close", command=top.destroy)
close_btn.pack()
open_button = Button(root, text="New Window", command=open_new_window)
open_button.pack(pady=20)
exit_button = Button(root, text="Close", command=root.destroy)
exit_button.pack(pady=20)
root.mainloop()
Method 2: link a variable
from tkinter import *
root = Tk()
root.title("Welcome screen")
root.geometry("300x300")
def do_stuff(text_entry):
print(text_entry.get())
def open_new_window():
top = Toplevel()
top.title("second window")
text_entry = StringVar()
entities = Entry(top, textvariable = text_entry)
entities.pack()
entities.focus_set()
sub_button = Button(top, text="Submit", command= lambda: do_stuff(text_entry))
sub_button.pack(pady=20)
close_btn = Button(top, text="Close", command=top.destroy)
close_btn.pack()
open_button = Button(root, text="New Window", command=open_new_window)
open_button.pack(pady=20)
exit_button = Button(root, text="Close", command=root.destroy)
exit_button.pack(pady=20)
root.mainloop()
The main advantage in this last approach is that you can play with the text before and after the entry is built.
def entering(a):
value=entry1.get() #entry1.get()is used to get values which entered in entry box
label1=Label(root, text =value, height=10)
label1.pack()
entry1.delete(0, END) # used to clear entry box
root.bind('<Return>',entering)
how do I remove the widget that I created in the function call entering?
I know about the destroy function. I don't want to destroy it after a particular time.
I want to destroy it or overwrite it into the widget when I call the function again
I think this is what you expect:
import tkinter as tk
root = tk.Tk()
myentry = tk.Entry(root)
myentry.pack()
var = tk.StringVar(root)
mylabel = tk.Label(root, textvariable= var)
mylabel.pack()
def entering(event):
text = myentry.get()
var.set(text)
myentry.bind('<Return>', entering)
root.mainloop()
I'm trying to build a very simple program in Python and Tkinter that allows the user to input people's names by keyboard and then a button is commanded to select a person from the list at random and show it in a tk.Label object.
My problem is once I run the root.mainloop(), I can add names to the list but the list does not update with the new names.
This is the main code for the Tkinter to initialize
import tkinter as tk
from tkinter import filedialog, Text
import random
root = tk.Tk()
root.title('Millor persona del moment')
root.geometry("500x200")
root.configure(bg='black')
peopleList = []
tk.Label(root, text="Insertar participante: ",fg="#ff007f", bg='black').grid(row=0)
e1 = tk.Entry(root)
e1.grid(row=0, column=1)
addButton = tk.Button(root, text='Añadir', padx=10, pady=5, fg="#ff007f", bg='black', command=addPerson)
addButton.grid(row=0, column=2)
while peopleList:
turnButton = tk.Button(root, text='Saca Tema', padx=10, pady=5, fg="#ff007f", bg='black', command=wordTurn(peopleList))
turnButton.grid(row=1, column=0)
nom = tk.StringVar()
nom.set('Comencem')
personSpeaking = tk.Label(root, textvariable=nom,fg="#ff007f", bg='black')
personSpeaking.grid(row=1, column=1)
root.mainloop()
And these are the functions I use
def addPerson():
peopleList.append(e1.get())
e1.delete(0,'end')
def wordTurn(peopleList):
person = random.choice(peopleList)
peopleList.remove(person)
nom.set(person)
command=wordTurn(peopleList)) calls the return value of wordTurn when the button is pressed, which is None and should raise an error. Use command=lambda peopleList=peopleList: wordTurn(peopleList)) instead.
I'm trying to add a file path to my application using an entry, but every time the entry returns an empty string
def command1(event):
if entry1.get() == 'localhost' and entry2.get() == 'amine' and entry3.get()=='aze123qsd' and entry4.get()=='GTFS':
top = Toplevel()
top.title("Add a file")
top.geometry("600x300")
text=Label(top ,text="Add the file path")
text.place(relx=0.3 ,rely=0.3)
entry=Entry(top)
entry.place(relx=0.5 ,rely=0.3)
paths=entry.get()
entry.bind('<Return>', commnad3)
button1 = Button(top, text="show the last window")
button1.place(relx=0.55 ,rely=0.7)
button2 =Button(top ,text="Use old data", command=old)
button2.place(relx=0.3 ,rely=0.7)
Your problem is due to creating entry at the same time you are performing get() on that entry. All you will have at that moment is an empty entry field.
You need to grab that entry information after something has been put into it.
Take this example and let me know if you have any questions.
import tkinter as tk
root = tk.Tk()
def print_entry(e):
print(e.get())
def command1():
top = tk.Toplevel()
entry = tk.Entry(top)
entry.pack()
tk.Button(top, text="Print Entry", command=lambda: print_entry(entry)).pack()
tk.Button(root, text="TOPLEVEL", command=command1).pack()
root.mainloop()
below is my code for creating a tool that takes a file path, stores the value, and then opens the specific file path selected by the user.
Currently, I'm looking to take the user entry mypathEntry that is stored in the mypathList listbox after clicking the Save button and add a command to it. The command will open that selected file path. My current code returns an error message regarding mypathList.add_command(command=Open) stating that Listbox instance has no attribute 'add_command'.
What is the syntax for adding a command to a listbox item?
from Tkinter import *
import os
root = Tk()
def Save():
fp = mypathEntry.get()
scribe = open('filepath.txt', 'w')
scribe.write(fp)
mypathEntry.delete(0, 'end')
mypathList.insert(1, fp)
def Open():
path = fp
menu = Menu(root)
##root.config(menu=menu)
##subMenu = Menu(menu)
##menu.add_cascade(label="Filepaths", menu=subMenu)
##subMenu.add_command(command=Save)
mypathLabel = Label(root, text="Copy and Paste your filepath here:")
mypathEntry = Entry(root, bg="black", fg="white", relief=SUNKEN)
mypathSaveButton = Button(root, text="Save Path", bg="black", fg="white", command=Save)
mypathList = Listbox(root, bg="black", fg="white")
mypathList.add_command(command=Open)
mypathLabel.pack()
mypathEntry.pack()
mypathSaveButton.pack()
mypathList.pack()
root.mainloop()
According to this,
http://effbot.org/tkinterbook/listbox.htm
The listbox item does not have a command option. So what you need to do instead is to bind an event to it. Here is a complete working example.
from tkinter import *
import os
root = Tk()
class MainGui:
def __init__(self, master):
self.mypathLabel = Label(master, text="Copy and Paste your filepath here:")
self.mypathEntry = Entry(master, bg="black", fg="white", relief=SUNKEN)
self.mypathSaveButton = Button(master, text="Save Path", bg="black", fg="white", command=self.save_path)
self.mypathList = Listbox(master, bg="black", fg="white")
self.mypathLabel.pack()
self.mypathEntry.pack()
self.mypathSaveButton.pack()
self.mypathList.pack()
self.mypathList.bind("<Double-Button-1>", self.open_path)
def save_path(self):
fp = self.mypathEntry.get()
self.mypathEntry.delete(0, 'end')
self.mypathList.insert(1, fp)
def open_path(self, event):
list_item = self.mypathList.curselection()
fp = self.mypathList.get(list_item[0])
print(fp)
try:
with open(fp, 'r') as result:
print(result.read())
except Exception as e:
print(e)
MainGui(root)
root.mainloop()
