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):
super(MainWindow,self).__init__()
self.initGUI()
def initGUI(self):
self.setWindowTitle("A Simple Text Editor")
self.setWindowIcon(QIcon('appicon.png'))
self.setGeometry(100, 100, 800, 600)
self.textEdit = QTextEdit()
self.setCentralWidget(self.textEdit)
self.fileName = None
self.filters = "Text files (*.txt)"
self.SetupComponents()
self.show()
# Function to setup...
