(A Python signal is one that is emitted in Python code; a Qt signal is one emitted from an underlying C++ object.) We can use this syntax both to emit Python and Qt signals, and to connect to them. These signals can be connected to any callable, that is, to any function or method, including Qt slots; they can also be connected using the SLOT In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. 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. These points are made in Summerfield's article on Signals and Slots.

Python is a powerful, easy-to-use scripting language suitable for use in the enterprise, although it is not right for absolutely every use. Python expert Martin Aspeli identifies when Python is the right choice, and when another language mi

Functions or methods are executed in response to user’s actions like clicking on a button, selecting an item from a collection or a mouse click etc., called events.

Some also offer gaming in dozens of other currencies as well. Používám Qt a C++. Jsou tam potřeba dvě vlákna -- jedno pro GUI a jedno pro čtení vstupu. Z toho vlákna pro čtení nemůžu pracovat s GUI komponentami a plnit do nich hodnoty, to je jasné. Dočetl jsem se, že nejsnazší způsob, jak tahle dvě vlákna propojit jsou signály a sloty. To jsem udělal a funguje mi to.

Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity. I'm assuming you're talking about QT's signals and slots. It's very simple. An instance of a class can fire a signal and another instance of perhaps another class can catch that signal in a slot. It's sort of like a function call only that the guy that calls the function doesn't need to know who wants to receive the call.
