Hi,
I'm trying to teach myself GUI programmming with the help of the new
PyQt book and the examples from the PyQt package. Although I've been
doing Python for five years I have a hard time doing OOP stuff.
Frankly, I never know when and where to put this "self" thing.
My script (see below) works (no wonder, it's cut down from the
application.pyw example). But as soon as I wanted to add a help action
it doesn't work. The help action is ripped from Mark Summerfield's
sandbox.pyw and calculate.pyw.
Can anyone help me with the help function?!

from PyQt4 import QtGui, \
QtCore
class MainWindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
# create actions
self.aboutAct = QtGui.QAction(self.tr('&About'), self)
self.aboutAct.setStatusTip(self.tr('Show the application\'s About box'))
self.connect(self.aboutAct, QtCore.SIGNAL('triggered()'), self.about)
self.helpAct = QtGui.QAction(self.tr('&Help'), self)
self.helpAct.setStatusTip(self.tr('Online help'))
self.connect(self.helpAct, QtCore.SIGNAL('triggered()'), self.help)
# create menus
self.helpMenu = self.menuBar().addMenu(self.tr('&Help'))
self.helpMenu.addAction(self.helpAct)
self.helpMenu.addAction(self.aboutAct)
# create status bar
self.statusBar().showMessage(self.tr('Ready'))
def about(self):
QtGui.QMessageBox.about(self, self.tr('About Application'),
self.tr('Application does something\n'
'This software comes without
warranty, liability or support!'))
def help(self):
browser = QtGui.QTextBrowser()
browser.append('Help')
layout = QtGui.QVBoxLayout()
layout.addWidget(browser)
app = QtGui.QApplication(sys.argv)
mainWin = MainWindow()
mainWin.show()
app.exec_()
