Introduction to PyQt4 Part 1

Overview

Here, we will give a rudimentary explanation of PyQt4. Basically, proceed with reference to [this site](http://myenigma.hatenablog.com/entry/2016/01/24/113413 #Create Window). The execution environment is as follows.

--OS: Ubuntu (running in BashOnUbuntuOnWindow) --Python: 2.7 series

If you don't know how to display GUI on BashOnUbuntuOnWindow, please refer to this site to build the environment.

Part 1 explains ** how to make a main window **

How to make a main window

makeWindow.py


#coding:utf-8
"""
A program to display a window with the smallest program
"""
import sys
from PyQt4 import QtGui

def main():
	app = QtGui.QApplication(sys.argv)	
	w = QtGui.QWidget()					#Creating a window
	w.resize(250,150)					#Resize window
	w.setWindowTitle('QtSample')
	w.show()
	sys.exit(app.exec_())				#app.exec_()Points to the cross button on the upper right

if __name__ == "__main__":
	main()

makeWindow.py is a program for creating windows.

w = QtGui.QWidget()

Create a window by

w.show()

Displays a window by.

When makeWindow.py is executed, the following screen will be displayed.
