Priyanshu
Tkinter is a GUI library in Python that is a fast and easy way to create GUI applications.
Initialization
To open Tkinter, follow the following steps:
- Import
Tkintermodule - Initialize an object to it and add required widgets
- Add object
name.mainloop()
The following steps are shown in the code below:
from tkinter import * obj = Tk() obj.mainloop()
Buttons
The Button object is used to display the button on your application:
new_button = Button(text= "button", command ="") new_button.pack()
Entry
The Entry object is used to display a single input text field line:
text_field = Entry() text_field.pack()
Label
The Label object is used to display a single text field line:
main_title = Label(text = "Hello") main_title.pack()
Geometry management
All the widget has to use is a specific geometry method and it is divided into three types. These types are:
Pack: organizes the widgets before placing them in the parent widget.
new_button = Button(text= "button", command ="") new_button.pack(side = BOTTOM) text_field = Entry() text_field.pack(side = LEFT) main_title = Label(text = "Hello") main_title.pack(side= RIGHT)
Place: you can provide an absolute position for where to place the widget.
new_button = Button(text= "button", command ="") new_button.place(height = 100, width = 100)
Grid: displays widgets in Table format.
new_button = Button(text= "button",width = 40, command ="") new_button.grid(row = 1, column = 0,columnspan = 2) text_field = Entry() text_field.grid(row = 0, column =1) main_title = Label(text = "Hello") main_title.grid(row = 0, column = 0)
