This page describes the use of signals and python @slot in Qt for Python. The examples here below will make it clearer.
It is necessary to inform the object, its signal via macro and more info slot to be connected to.
In addition to that, it can receive also a named argument name that defines the signal name. Signal' python @slot has no attribute 'connect'. Views Read View source View history. If nothing is passed as name then the new slot will have the python @slot name as the function that is being decorated.
Again, to define a signature just pass the types like the QtCore. The connect method has a non python-friendly syntax.
Unlike the Signal class, to overload a function, you don't pass every variation as tuple or list. If you need to overload it just pass the types as tuples or lists. This is the old way of using signals and slots.
Namespaces Page Discussion. Instead, you have to define a new decorator for every different signature. QPushButton 'Say hello! The new-style uses a different syntax to create and to connect signals and slots.

Slots are assigned and overloaded using the decorator QtCore. The main goal of this new-style is to provide a more Pythonic syntax to Python programmers. QApplication sys. Signals can be defined using the QtCore. As 'int' is the default 21 we have to specify the str when connecting the 22 second signal 23 someone. Python types and C types can be passed as parameters to it. This way the signal information is added to the class QMetaObject structure. The result keyword defines the type that will be returned and can be a C or Python type. The previous example could be rewritten as:. Navigation Main page Recent changes Random page Help. The emphasis is on illustrating the use of so-called new-style signals and slots, although the traditional syntax is also given as a reference. Another difference is about its keywords. Slot accepts a name and a result. If nothing is passed as name then the new signal will have the same name as the variable that it is being assigned to. The example below uses the well known clicked signal from a QPushButton. Note: Signals should be defined only within classes inheriting from QObject. The examples below illustrate how to define and connect signals and slots in PySide2. Signal class.
