Hello, I have two classes that I create instances of during run time. I am trying to connect a signal and a slot of the two instances, however I am not sure how to do this because upon initialization the instances point to nothing and only get created somewhere in the middle of my application running. Qt for Python Signals and Slots - Qt Wiki Traditional syntax: SIGNAL and SLOT() QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton.The connect method has a non python-friendly syntax.

Meta-object System - Wikipedia Meta Object System is a part of Qt framework core provided to support Qt extensions to C++ like signals/slots for inter-object communication, run-time type information, and the dynamic property system.

2009-11-2 · In the class's private section, we declare two slots. To implement the slots, we will need to access most of the dialog's child widgets, so we keep pointers to them as well. The slots keyword is, like signals, a macro that expands into a construct that the C++ compiler can digest.
Signals and slots - Wikipedia Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots. This is similar to C/C++ function pointers, but Dynamic language tricks in C++, using Qt - EPx Signals and slots: implementation. After having worked with languages like Python and Objective C, it is kind of instinctive to search for dynamic features in Qt, to the point that it feels impossible to do something with bare C++ (without Qt Core at least).
