What I've done
- Italian e-book - Introduzione a PyQt4 2 Edizione, 15 pages!
- github.com/Mte90/PyQT-Boilerplate - Create a PyQt4/5 software pretty easy!
- github.com/Mte90/QAsana - Asana client with hotkey and auto position on multimonitor screen
- github.com/Mte90/Plessc - Gui frontend for lessc
- github.com/Mte90/PenMode-QT - [Abandoned] Frontend for Penmode (wrapper for various hacking tools)

Interface
Interface to Python code
- *.ui are XML files generated by QtDesigner
- pyuic4 -x mainWindow.ui -o MainWindow.py - for PyQt4
- pyuic5 -x mainWindow.ui -o MainWindow.py - for PyQt5
- Why?
- Better integration with IDE/Editor
- Better to read instead of a XML file
Time to try the interface with the boilerplate!
What are the Slots and Signals?
One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components.
Signal is emitted when something of potential interest happens.
Slot is a Python callable.
self.ui.newQuestionButton.clicked.connect(self.new_question)
Time to code!
