PySide: Standard Dialogs and Message Boxes

The PySide GUI toolkit for Python has several standard dialogs and message boxes that you can use as-is. You can also create custom dialogs, but we’ll be saving that for a future article. In this post, we will cover the following dialogs: Color Dialog File Dialog Font Dialog Input Dialog Print & Print Preview Dialogs

PySide: Connecting Multiple Widgets to the Same Slot

As I learn PyQt and PySide, I am writing some tutorials to help my fellow travelers. Today we’ll be looking at how to connect multiple widgets to the same slot. In other words, we’ll be binding the widgets signals (basically events) to slots (i.e. callables like functions, methods) which are better known as “event handlers”.

PySide: Creating a Currency Converter

I am currently reading through Mark Summerfield’s book on PyQt, Rapid GUI Programming with Python and Qt and thought it would be fun to take some of the example applications in it and convert them to PySide. So I’ll be creating a series of articles where I’ll show the original PyQt examples from the book

wxPython: How to Double-click an Item in an ObjectListView Widget

This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks

Real Python for Web Development Book on Kickstarter

Last week I was contacted about a cool sounding book project on Kickstarter: Real Python for Web Development, featuring web2py by Michael Herman. I have to admit that I’m not familiar with Mr. Herman or the person who originally contacted me about the book, but since I enjoy reading Python books and this one sounded

Python 101: Exception Handling

Python provides robust exception handing baked right into the language. Exception handing is something every programmer will need to learn. It allows the programmer to continue their program or gracefully terminate the application after an exception has occurred. Python uses a try/except/finally convention. We’ll spend some time learning about standard exceptions, how to create a
