Python GUI Development Libraries

In this article we are going to introduce Python GUI Development Libraries, so a you know

Python is one of the best programming language, and there are different sections that you

can use Python, one of them is using Python in GUI Development. there are different GUI Libraries

in Python that you can build User Interface applications, we want to introduce the most popular

and powerful Python GUI Development Libraries.

Python Top 5 Game Libraries

1: PyQt5

My first choice on GUI Development with Python is PyQt5, it is one of the best and powerful

libraries in building GUI application,PyQt is a binding of Qt5 C++ a gui framework for c++

developers. you can create program in pyqt5 using coding or a using qt designer a visual dialog

that you can drag and drop UI widgets. PyQt5 is a free Python bindings software open source

widget-toolkit Qt, implemented for cross-platform application development framework. In the free

version, certain features may not be available but if your application is open source then you can use

it under a free license. PyQt is available on Windows, MacOSX, Linux, Android iOS and Raspberry

Pi.

Installation

You can use pip for the installation

pip install pyqt5

1	pip install pyqt5

Creating first window in pyqt5

from PyQt5.QtWidgets import QApplication,  QMainWindow
import sys
from PyQt5 import QtGui


class Window(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setGeometry(300, 300, 500, 400)
        self.setWindowTitle("PyQt5 Window")

        self.show()




App = QApplication(sys.argv)
window = Window()
sys.exit(App.exec())

from PyQt5.QtWidgets import QApplication, QMainWindow

import sys

from PyQt5 import QtGui

class Window(QMainWindow):

def __init__(self):

super().__init__()

self.setGeometry(300, 300, 500, 400)

self.setWindowTitle("PyQt5 Window")

self.show()

App = QApplication(sys.argv)

window = Window()

sys.exit(App.exec())

Run the complete code and this is the result

2: TKinter

If you are looking completely free library for GUI Development in Python, than your choice

will be tkinter. Tkinter is the most popular programming package for graphical user

interface or desktop apps. It is so named because of its simplicity. Tkinter is the combination

of Tk and Python’s standard GUI framework. Tkinter It provides diverse widgets, such as

labels, buttons, and text boxes used in a graphical user interface application. The Button

control also called widgets are used to display buttons in developed application while the

Canvas widget is used to draw shapes (lines, ovals, polygon…) in your application.

It is a built in library for python.

Installation

It is a built in library in python, no need to install

Creating example in TKinter

from tkinter import *



class Root(Tk):
    def __init__(self):
        super(Root, self).__init__()
        self.title("Geekscoders.com - TKinter Window")
        self.minsize(400, 300)






root = Root()
root.mainloop()

from tkinter import *

class Root(Tk):

def __init__(self):

super(Root, self).__init__()

self.title("Geekscoders.com - TKinter Window")

self.minsize(400, 300)

root = Root()

root.mainloop()

Run the complete code and this is the result.

3: Pyside2 (Qt For Python)

Qt for Python offers the official Python bindings for Qt (PySide2), enabling the use

of its APIs in Python applications, and a binding generator tool (Shiboken2) which

can be used to expose C++ projects into Python. Qt for Python is available under

the LGPLv3/GPLv3 and the Qt commercial license.

Installation

pip install PySide2

1	pip install PySide2

Creating first window in PySide2(Qt For Python)

from PySide2.QtWidgets import QApplication,QWidget
import sys
import time



class Window(QWidget):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Pyside2 Simple Application")
        self.setGeometry(300,300,500,400)




myApp = QApplication(sys.argv)
window = Window()
window.show()
myApp.exec_()
sys.exit(0)

from PySide2.QtWidgets import QApplication,QWidget

import sys

import time

class Window(QWidget):

def __init__(self):

super().__init__()

self.setWindowTitle("Pyside2 Simple Application")

self.setGeometry(300,300,500,400)

myApp = QApplication(sys.argv)

window = Window()

window.show()

myApp.exec_()

sys.exit(0)

Run the code and this is the example

4: Kivy

Kivy is Open source Python library for rapid development of applications that make

use of innovative user interfaces, such as multi-touch apps. Kivy runs on Linux, Windows,

OS X, Android, iOS, and Raspberry Pi. you can run the same code on all supported platforms.

It can natively use most inputs, protocols and devices including WM_Touch, WM_Pen,

Mac OS X Trackpad and Magic Mouse, Mtdev, Linux Kernel HID. Kivy is 100% free to use,

under an MIT license, The toolkit is professionally developed, backed and used.

You can use it in a commercial product. the framework is stable and has a well

documented API, plus a programming guide to help you get started.

Installation

Before installing Kivy, you need to install the following dependency and after that you

can install kivy.

pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew

1	pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew

pip install Kivy

1	pip install Kivy

Creating first example in Kivy

from kivy.app import App
from kivy.uix.button import Label


class TestApp(App):
    def build(self):
        return Label(text = "Geekscoders.com - Kivy Window")




TestApp().run()

from kivy.app import App

from kivy.uix.button import Label

class TestApp(App):

def build(self):

return Label(text = "Geekscoders.com - Kivy Window")

TestApp().run()

Run the complete code and this is the result.

5: wxPython

wxPython is a cross-platform GUI toolkit for the Python programming language.

It allows Python programmers to create programs with a robust, highly functional

graphical user interface, simply and easily. It is implemented as a set of Python extension

modules that wrap the GUI components of the popular wxWidgets cross platform library,

which is written in C++.

Like Python and wxWidgets, wxPython is Open Source, which means that it is free

for anyone to use and the source code is available for anyone to look at and modify. And

anyone can contribute fixes or enhancements to the project.

wxPython is a cross-platform toolkit. This means that the same program will run on multiple

platforms without modification. Currently Supported platforms are Microsoft Windows,

Mac OS X and macOS, and Linux.

Installation

pip install wxPython

1	pip install wxPython

Creating first window in wxPython.

import wx


class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title, size = (400,300))


        self.panel = MyPanel(self)





class MyPanel(wx.Panel):
    def __init__(self, parent):
        super(MyPanel, self).__init__(parent)




class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame(parent=None, title="Geekscoders.com - wxPython Window")
        self.frame.Show()
        return True



app = MyApp()
app.MainLoop()

import wx

class MyFrame(wx.Frame):

def __init__(self, parent, title):

super(MyFrame, self).__init__(parent, title=title, size = (400,300))

self.panel = MyPanel(self)

class MyPanel(wx.Panel):

def __init__(self, parent):

super(MyPanel, self).__init__(parent)

class MyApp(wx.App):

def OnInit(self):

self.frame = MyFrame(parent=None, title="Geekscoders.com - wxPython Window")

self.frame.Show()

return True

app = MyApp()

app.MainLoop()

Run the complete code and this is the result

Conclusion

All of them are good libraries, if you want powerful library than you can go with PyQt5 or Pyside2, but they are not free, if you want for commercial purposes than you need to buy the license, if you want free gui library in python than you can go with tkinter or wxPython, also kivy is another choice.
