Keyboard enter key to function as a submit button

I
Captureh
want to enable keyboard enter key to function as a submit button in Python gui for a simple windows desktop application.

I’ve not built many Tkinter apps, but I do have some notes about such, so, from my notes, I have this:

import tkinter as tk

app = tk.Tk()
app.geometry("200x100")


def key_return(event):
    label["text"] = "You pressed Enter"


def key_h(event):
    label["text"] = "You pressed h"


app.bind('<Return>', key_return)
app.bind('<h>', key_h)

label = tk.Label(app, text="")
label.pack()

app.mainloop()

… which demonstrates what (I think) you’re trying to do.

from tkinter import *
import pandas as pd
import tkinter.messagebox
from tkinter import ttk # for treeview
import tkinter as tk
from tkinter import Tk, BOTH, Menu
root = tk.Tk()
root.geometry(“550x400” ) # width x height
root.title(“Dispatch Assist”) # Adding a title
root.configure(background=‘#ccccff’)
root.minsize(540, 300)
root.maxsize(650, 450)

trv = ttk.Treeview(root)

df = pd.read_excel(“C:\Users\fr\pythonProject7\data\data.xlsx”) # create DataFrame

trv.column(“#0”, minwidth=650)
l1 = tk.Label(root, text=“Enter Word”, background=‘#ccccff’, width=10, font=(‘georgia 14’)) # add one Label
l1.place(x=50,y=35)
e1 = tk.Entry(root, width=25, font=18 ) # added one Entry box

e1.place(x=165,y=40)

b1 = tk.Button(root, text=“Search”, width=7, background=“#b3b3ff”, font=('georgia 14 bold '), command=lambda: my_search())
b1.place(x=400,y=30)

#text = tk()

def pop_menu(event):
menu.tk_popup(event.x_root, event.y_root)

def copy():
e1.event_generate(“<>”)

def cut():
e1.event_generate(“<>”)

def paste():
e1.event_generate(“<>”)

def select_all():
e1.event_generate(“<>”)
#Right Click Menu
menu = Menu(e1, tearoff=0, bg=“black”, fg=“white”)
#options
menu.add_command(label=“Copy”, command=copy)
menu.add_command(label=“Cut”, command=cut)
menu.add_separator()
menu.add_command(label=“Paste”, command=paste)
menu.add_separator()
menu.add_command(label=“Select All”, command=select_all)

#Make the menu pop up
e1.bind(“<Button - 3>”, pop_menu)

def ex() :
tkinter.messagebox.showinfo(“Program”,‘Exit’)
exit()

def hel():
help(“C:\Users\fr\pythonProject7\help.txt”)
def my_search():
#file_menu = Menu(menubar, tearoff=False)
l1 = list(df) # List of column

root.bind(‘’, my_search)

# names as headers
query= e1.get().strip().lower() # get user entered string


if query.isdigit():  # if query is number
    str1 = df["id"] == int(query)  #

else:
    str1 = df.Key_Word.str.contains(query, na=False)  # name column value matching

df2 = df[(str1)]  # combine all conditions using | operator
r_set = df2.to_numpy().tolist()  # Create list of list using rows
trv = ttk.Treeview(root, selectmode="browse")  # selectmode="browse" or "extended"
trv.grid(row=10, column=2, columnspan=2, padx=20, pady=110)  #
trv["height"] = 10  # Number of rows to display, default is 10
trv["show"] = "headings"
# column identifiers
trv["columns"] = l1
for i in l1:
    trv.column(i, width=250, anchor="c")

#Headings of respective columns
trv.heading(i, text=i)
for dt in r_set:
v = [r for r in dt] # creating a list from each row
trv.insert( “”, “end”,iid=v[0], values=v) # adding row

del df[‘list’] #delete ‘list’ column
#keyboard.press(‘enter’)

menu = Menu(root)
root.config(menu=menu)

subm = Menu(menu)
menu.add_cascade(label=“File”, menu=subm)

subm.add_command(label=“Exit”, command=ex)

subml1 = Menu(menu)
menu.add_cascade(label=“Tools”,menu=subml1)
subml1.add_command(label=" Help", command=hel)

root.mainloop()
