1] Signal and Slot Example in PyQt5 - Manash’s blog Signal-Slot is one of the fundamental topics of Qt one should have a firm grasp to write Qt applications. I have been developing Qt C++ application on Windows/Linux platforms about 3 and a half year so I know a bit about signal-slot and how to connect and disconnect them. Differences Between PySide and PyQt - Qt Wiki PyQt provides two different APIs, the first of which provides QStrings, QVariants, etc as is in Python. The new API 2 provides automatic conversion between the Qt classes and respective native Python datatypes and is much more Pythonic in nature. PyQt on Python 2.x defaults to API 1, while PyQt on Python 3 defaults to API 2. PySide/PyQt Tutorial: Creating Your Own Signals and Slots ...

Put any code snippet for PyKDE and PyQt that you find useful here. If the code is longer than one screen at normal point size, it might be better if you provide a rationale and a link, or just put it on a separate page. PyQt 3. Note: PyQt 3 examples have not been transferred from the old PyQt Wiki.
Passing data between classes with Signals in PyQt mysignal = pyqtSignal(str).Python-passing variable between classes. Passing data between controllers with a service. Qt signals and slots passing data.
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 PyQt_PyObject value declaration with an old-style signal-slot connection, and again when the signal is emitted, to communicate a Python dictionary. Development/Tutorials/Python introduction to signals and ... It's possible to send a python object of any type using PyQt_PyObject in the signature. This is recommended when both signal and slot is implemented in python. By using PyQt_PyObject we avoid unnecessary conversions between python objects and C++ types and it is more consistent with python dynamically typed nature.
