Pyqt New Style Signals And Slots

1. This section describes the new style of connecting signals and slots introduced in PyQt4 v4.5. One of the key features of Qt is its use of signals and slots to communicate Their use encourages the development of reusable components.
2. Source Codes: PyQt5 Signal And Slots Basics Pyhton GUI Programming Graphical applications (GUI) are event-driven, unlike.
3. Sending Python values with signals and slots. On the #pyqt channel on Freenode, Khertan asked about sending Python values via Qt's signals and slots mechanism. The following example uses the PyQtPyObject value declaration with an old-style signal-slot connection, and again when the signal is emitted, to communicate a Python dictionary.

There are some concepts to be clarified

[QT signal & slot] VS [Python signal & slot]

All the predefined signals & slots provided by pyqt are implemented by QT's c++ code. Whenever you want to have a customized signal & slot in Python, it is a python signal & slot. Hence there are four cases to emits a signal to a slot:

• from a QT signal to a QT slot
• from a QT signal to a Python slot
• from a Python signal to a QT slot
• from a Python signal to a Python slot

The code below shows how to connect for these four different scnarios

Conclusion is --

Signals And Slots Pyqt5

Signal signature for Python signal differentiate from that of QT signal in that it doesn't have the parenthesis and can be passed any python data types when you emit it. The Python signal is created when you emit it.

For slot, there are three forms of signatures.

• s.connect(w, SIGNAL('signalSignature'), functionName)
• s.connect(w,SIGNAL('signalSignature'), instance.methodName)
• s.connect(w,SIGNAL('signalSignature'), instance, SLOT('slotSignature'))

Number 1 & 2 are available for Python slot, while number 2 & 3 are available for QT slot. It is clear that besides QT predefined slot, any python callable function/methods is qulified to be a Python slot.

Well, all the description above is based on the old style pyqt signal & slot. As @Idan K suggested there is an alternative new-style to do the things, especially for the Python signal. Refer to here for more.
