Overview of this book

Elegantly-built GUI applications are always a massive hit among users. PySide is an open source software project that provides Python bindings for the Qt cross-platform UI framework. Combining the power of Qt and Python, PySide provides easy access to the Qt framework for Python developers and also acts as an excellent rapid application development platform. This book will take you through everything you need to know to develop UI applications. You will learn about installing and building PySide in various major operating systems as well as the basics of GUI programming. The book will then move on to discuss event management, signals and slots, and the widgets and dialogs available with PySide. Database interaction and manipulation is also covered. By the end of this book, you will be able to program GUI applications efficiently and master how to develop your own applications and how to run them across platforms.

A simple text editor

The following is the implementation of a simple text editor that is extended from the previous examples in its building version. This code contains some new features, such as QFontDialog, QFileDialog, and so on, which are discussed in Chapter 5, Dialogs and Widgets. Otherwise, the following code is self explanatory:

# Import required modules
import sys, time
from PySide.QtGui import *

# Our main window class
class MainWindow(QMainWindow):
    # Constructor function
    def __init__(self, fileName=None):

    def initGUI(self):
        self.setWindowTitle("A Simple Text Editor")
        self.setGeometry(100, 100, 800, 600)

        self.textEdit = QTextEdit()
        self.fileName = None

        self.filters = "Text files (*.txt)"

    # Function to setup...
