import tkinter as tk from tkinter import ttk class Window(tk.Tk): def __init__(self): super(Window, self).__init__() self.title("TextBox") self.minsize(500,400) self.wm_iconbitmap("myicon.ico") self.text_entry() def click_me(self): self.label.configure(text = "Hello " + self.name.get()) self.label.config(font=("Courier", 20)) def text_entry(self): self.name = tk.StringVar() self.label = ttk.Label(self, text = "Enter Your Name") self.label.grid(column = 0, row = 0) self.textbox = ttk.Entry(self, width = 20, textvariable = self.name) #added focus to textbox self.textbox.focus() self.textbox.grid(column=0, row=1) self.button = ttk.Button(self, text = "Click ME", command = self.click_me) self.button.grid(column=0, row=2) #The button is disabled self.button.configure(state = "disabled") window = Window() window.mainloop() |
In here we have used two new line of codes, this is used for giving focus for the textbox or text entry.
|
1 |
self.textbox.focus() |
This is used for disabling the button.
|
1 |
self.button.configure(state = "disabled") |
Run the code and this will be the result, we have focus widget for the textbox and the buttons is disabled.
