Transmit extra data with signals in PyQt 13.01.2014

Signals are a neat feature of Qt that allow message-passing between different areas of your program. To use a signal you attach a function to be called in the event of the signal firing, usually accepting a small item of data about the signal state. However, there is a limitation: the signal can only emit the data it was designed to do. So for example, a QAction has a .triggered that fires when that particular action has been activated. Unfortunately the receiving connected function only receives one thing: checked=True or False. In other words, the receiving function has no way of knowing which action triggered it. This is usually fine. You can tie a particular action to a particular function. However, sometimes you want to trigger multiple actions off the same type of action, and treat them differently. Here’s a neat trick to do just that.
