I am a newbie, working on developing a GUI with PyQT. I tried your exercise. ^ ^
But somehow the slot doesn’t work, and the text on my pushbutton does not even change, let alone toggle. > <

from PyQt4.QtCore import SIGNAL, SLOT
from PyQt4.QtGui import QApplication, QWidget, QPushButton, QLabel, QVBoxLayout
import sys

if __name__==’__main__’:
App = QApplication(sys.argv)
Window = QWidget()
Window.setWindowTitle(“PushButton Toggle Exercise”)
Layout = QVBoxLayout(Window)
Button = QPushButton()
Button.setText(‘Default’)
Layout.addWidget(Button)
MyString = ‘Welcome!’
Button.connect(Button, SIGNAL(“pressed()”), Button, SLOT(“setText(MyString)”))
Window.show()
App.exec_()

Nice. The article itself is pretty good. The diagrams are self explanatory and help a lot. At the risk of sounding like a n00b i would suggest at u put up a list of packages to get he PyQt devel environment up and running. Sometimes this can be a pain. Sometimes. Keep the articles coming. :) I had done a bit of GTK+ coding a few months back and the flow of things that you are following are pretty much the same that i followed then. Nice.
