[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. Pyqt4 Signals And Slots Tutorial. pyqt4 signals and slots tutorial In this part of the PyQt4 tutorial, we work with events and signals. We connect a signal to a slot, reimplement an event handler, and emit a custom WOWMONEY.EU introduction to creating PySide/PyQt signals and slots, using QObject. This signal does nothing, by itself; it must be connected to a slot, which is an object that acts as a recipient for a signal and, given one, acts on it. Connecting Built-In PySide/PyQt Signals Qt widgets have a number of signals built in.

I am writing my first Python app with PyQt4. For each star drawn, we send the main thread information about where it should be placed along with the star's image by emitting our custom output signal: QAbstractButton has the following signal:.

Unfortunately, slot is not invoked. I tried with no arguments as well, different styles of emitting signal. No errors, no warnings in the code. What might be the problem? Signals must have the same signature. By the way, if you are defining your own signals, don't define parametres. Check, if this helps: Hence there are four cases to emits a signal to a slot:.

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. These points are made in Summerfield's article on Signals and Slots. As Idan K suggested there is an alternative new-style to do the things, especially for the Python signal. Refer to here for more. I checked your code and it looks like the problem is in the way how you're connecting your signal.

As noted by gruszczy you have to use the same QtCore. Also I think you should use Qt types in the arguments list of signal function. I haven't used PyQT4 but take a look at here.

Details

One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components. A signal is emitted when something of potential interest happens.

A slot is a Python callable. If a signal is connected to a slot then the slot is called when the signal is emitted. The code or component that emits the signal does not know or care if the signal is being used. A signal specifically an unbound signal is an attribute of a class that is a sub-class of QObject. When a signal is referenced as an attribute of an instance of the class then PyQt4 automatically binds the instance to the signal in order to create a bound signal.

This is the same mechanism that Python itself uses to create bound methods from class functions. A bound signal has connect , disconnect and emit methods that implement the associated functionality.

A signal may be overloaded, ie. A signal may be indexed with a signature in order to select the one required. A signature is a sequence of types. New signals can be defined as class attributes using the pyqtSignal factory. New signals should only be defined in sub-classes of QObject. They must be part of the class definition and cannot be dynamically added as class attributes after the class has been defined. The following is an example of this:.

Signals are connected to slots using the connect method of a bound signal. Signals are disconnected from slots using the disconnect method of a bound signal. Disconnect one or more slots from a signal. An exception will be raised if the slot is not connected to the signal or if the signal has no connections at all. Signals are emitted from using the emit method of a bound signal. The following code demonstrates the definition, connection and emit of a signal without arguments:.

They were trained by their anthropomorphic rat sensei in the art of ninjutsu. From their home in the sewers of New York City , they battle petty criminals, evil overlords, mutated creatures, and alien invaders while attempting to remain hidden from society. They were created by Kevin Eastman and Peter Laird.

The characters originated in comic books published by Mirage Studios and expanded into cartoon series, films, video games, toys, and other merchandise. The concept arose from a humorous drawing sketched out by Eastman during a casual evening of brainstorming and bad television with Laird. The Turtles started their rise to mainstream success when a licensing agent, Mark Freedman, sought out Eastman and Laird to propose wider merchandising opportunities for the franchise.

In , Dark Horse Miniatures produced a set of mm approximately 0. In January , Eastman and Laird visited the offices of Playmates Toys , a small California toy company that wanted to expand into the action-figure market. Development was undertaken by a creative team of companies and individuals: Jerry Sachs, advertising agent of Sachs-Finley Agency, brought together the animators at Murakami-Wolf-Swenson headed by Fred Wolf.

Aaronian brought on several designers and concepteur and writer John C. Schulte , and worked out the simple backstory that would live on toy packaging for the entire run of the product and show.

The sense of humor was honed with the collaboration of the Murakami-Wolf-Swenson animation firm's writers. Playmates and their team essentially served as associate producers and contributing writers to the miniseries that was first launched to sell-in the toy action figures. Phrases like "Heroes in a half shell" and many of the comical catch phrases and battle cries "Turtle power!
