Using "Add" button, I want takes values from combobox into writen into entry. I also keep track of the existing values from on each click rather than allowing the user to select multiple names. For example:
When user select g from combobox and click add button, in textbox wroten "Selected letter: g"
After user select Q and click add button, in textbox wroten "Selected letter g,Q"
After user select p and click add button, in textbox wroten "Selected letter g,Q,p"
I think I confused on defining function "Add" button. Thanks.
import tkinter as tk
from tkinter.ttk import Combobox
form=tk.Tk()
form.title("Pi Theorem")
form.geometry("300x300")
x=tk.StringVar()
def Add():
textbox.insert(x)
#buton
buton=tk.Button(form,text='EKLE',fg='black',command=Add)
buton.place(x=200,y=50,height=20)
#entry - textbox
textbox=tk.Entry(fg='black',bg='white')
textbox.pack(ipady=10)
textbox.place(width=150,height=20,x=20,y=100)
#combobox
degiskenler=['g','Q','p','H','M']
combobox=Combobox(form, values=degiskenler,textvariable=x,height=3)
combobox.pack()
combobox.place(width=150,height=20,x=20,y=50)
form.mainloop()
CodePudding user response:
To get the value of the combobox in tkinter just use this command:
combobox.get()
Here is the final code:
import tkinter as tk
from tkinter.ttk import Combobox
form=tk.Tk()
form.title("Pi Theorem")
form.geometry("300x300")
def Add():
textbox.insert(END, combobox.get())
#buton
buton=tk.Button(form,text='EKLE',fg='black',command=Add)
buton.place(x=200,y=50,height=20)
#entry - textbox
textbox=tk.Entry(fg='black',bg='white')
textbox.pack(ipady=10)
textbox.place(width=150,height=20,x=20,y=100)
#combobox
degiskenler=['g','Q','p','H','M']
combobox=Combobox(form, values=degiskenler,height=3)
combobox.pack()
combobox.place(width=150,height=20,x=20,y=50)
form.mainloop()
There is no text variable in this. Simply take the value and put it in the end of the entrybox.
Thank You!
