Python Tkinter Button

Introduction to Python Tkinter button

Python Tkinter button is one of the most popularly used graphical user interface in python to design buttons in GUI’s. Here, the button widget in Tkinter is used to build various types of buttons in the GUI interfaces that are being developed.

Syntax:

Button(master,option=value,)

Attributes of Python Tkinter Button

Following are the list of attributes:

Examples 0f Python Tkinter Button

Given below are some of the examples of Tkinter:

Example #1

Code:

import tkinter as tk
Object creation for tkinter
parent = tk.Tk()
button = tk.Button(text="QUIT",
bd=10,
bg="grey",
fg="red",
command=quit,
activeforeground="Orange",
activebackground="blue",
font="Andalus",
height=2,
highlightcolor="purple",
justify="right",
padx=10,
pady=10,
relief="groove",
)
pack geometry manager for organizing a widget before palcing them into the parent widget.
possible options "Fill" [X=HORIZONTAL,Y=VERTICAL,BOTH] "side" [LEFT,RIGHT,TOP,UP] "expand" [YES,NO] button.pack(fill=tk.BOTH,side=tk.LEFT,expand=tk.YES)
kick the program
parent.mainloop()

Output:

Explanation:

For implementing the GUI functions using tkinter, the tkinter library needs to be installed. It can be installed using pip or any other standard python install technique. The program starts with the import of the tkinter library with the reference name of tk. an object for the tkinter class is created in the name of the parent. Next, a button variable is declared with the listed attribute values,

• Width of the border: 10
• Background-color: grey
• Foreground color: red,
• Operation Command: quit
• Active Foreground color: Orange
• Active background-color: blue
• Font: Andalus
• Height: 2
• Highlight color: purple
• Justification for Alignment: right
• Padding for x-axis: 10
• Padding for the y-axis: 10
• Relief Value: groove

Initiating the above-given arguments generates a button accordingly; from the generated button being a widget, it is packed into the parent widget using the pack command. Technically, the pack command is in the form of the method pack(). Applying this method to the variable button initiates a widget with the mentioned properties over the base widget. the base widget which is being used here could be a panel or any other graphical user interface. the pack() method is associated with three major arguments when encapsulating the button variable.

They are as below:

• Fill: X=HORIZONTAL, Y=VERTICAL, BOTH
• side: LEFT,RIGHT,TOP,UP
• expand: YES, NO

At last, the mainloop() function of the Tkinter object is triggered for setting up the GUI creation program into execution. We can notice an active button being prompted on the execution of the program being placed on a sophisticated GUI panel.

Example #2

Code:

import tkinter as tk
Object creation for tkinter
parent = tk.Tk()
button = tk.Button(text="QUIT",
bd=10,
bg="black",
fg="white",
command=quit,
activeforeground="Orange",
activebackground="blue",
font="calibri",
height=2,
highlightcolor="purple",
justify="left",
padx=2,
pady=2,
relief="ridge",
)
pack geometry manager for organizing a widget before palcing them into the parent widget.
button.pack()
kick the program
parent.mainloop()

Output:

Explanation:

This program is very much similar to the above one functionally, nut the properties of the widget which has been created are widely modified here. First, let us discuss the various display properties which are nicely associated with this button widget,

• Width of the border: 10
• Background-color: black
• Foreground color: white,
• Operation Command: quit
• Active Foreground color: Orange
• Active background-color: blue
• Font: calibri
• Height: 2
• Highlight color: purple
• Justification for Alignment: left
• Padding for x-axis: 2
• Padding for the y-axis: 2
• Relief Value: ridge

Again here initiating the over mentioned arguments creates a button accordingly like before, And also here the packing of the widget is carried on more precisely to mention the application is considered to be destroyed without the packing operation in its position. Hence, being packed is a default operation to take place, but on different terms here, the packing is achieved by placing zero arguments. Still, on different terms here, the packing is achieved by means of placing zero arguments. This means all the argument value for the packing process is settled with its default association.

At last, the mainloop() function of the Tkinter object is triggered for setting up the GUI creation program into execution. We can notice an active button being prompted on the execution of the program being placed on a sophisticated GUI panel.

Conclusion

Tkinter offers some among the cool options for graphical user interface design, and the predominant form of button design and executions are covered in a detailed manner.
