Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.

Support for Signals and SlotsΒΆ 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.

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.

Events and Signals in PyQt4 In this part of the PyQt4 programming tutorial, we will explore events and signals occurring in applications.
Events All GUI applications are event-driven.
Events are generated mainly by the user slot palace on facebook an application.
But they can be generated by other means as well: e.
The main loop fetches events and sends them to the objects.
The event object event encapsulates the state changes in the event source.
The event target is the object that wants to be notified.
Event source object delegates the task of handling an event to the event target.
PyQt4 has a unique signal and slot mechanism to deal slot palace on facebook events.
Signals and slots are used for communication between objects.
A signal is emitted when a particular event occurs.
A slot can be any Python callable.
A slot is called when a signal connected to it is emitted.
SIGNAL 'clicked 'self.
QSlider to a slot of a QtGui.
QLCDNumber and a QtGui.
We change the lcd number by dragging the slider knob.
The sender is an object that sends a signal.
The receiver is the object that receives slot palace on facebook signal.
The slot is the method that reacts to the signal.
Event sender Sometimes it is convenient to know which widget is the sender of a signal.
For this, PyQt4 has the sender method.
QPushButton "Button 1", self btn1.
QPushButton "Button 2", self btn2.
In the buttonClicked method we determine which button we have clicked by calling the sender method.
In the statusbar of the application, we show the label of the button being pressed.

QObject can emit signals.
In the following example we will see how we can emit custom signals.
This signal is slot palace on facebook during a mouse press event.
The signal is connected to the please click for source slot of the QtGui.

PyQt4 has a special type of signal called a short-circuit Signal. This signal implicitly declares all arguments to be of type PyQt_PyObject. Short-circuited signals do not have argument lists or parentheses. Short-circuited signals can only be connected to python slots. The same example as above, using short-circuited signals.

In Python however, any function can be a slot – we saw this above. For this reason, the distinction between slots and "normal" functions has little relevance for us. Signals are ubiquitous in Qt. And of course, you can also define your own. This however is beyond the scope of this tutorial. Compile your app

Pyqt4 signals and slots tutorial have noticed that there are a lot of users, myself included, who don't quite grasp the concept of signals and slots in Qt.
I was hoping to get some clarification on the following: I have a function that runs as soon as the GUI is built, this takes the information from a list and puts it into a string which is then uploaded to a texbox.
At the bottom of this loop, I want it to call a function in the parent thread via signals and slots, as recommended by other users.
Is this the proper way to do it?
I also get an error that says that the Main Window object has no attribute "trigger",why is this?
The reason you get that error is exactly the reason described by the error message - the signal trigger has not been defined anywhere in your class.
Signals and slots are used to communicate between different objects.
In your example you link trying to do everything from within your MainWindow class and there is no interaction with other objects.
You also only need to make the call to connect once.
You would typically call this either in the class constructor or from your main function after instantiating the objects you want to connect together.
Take a look at for some examples of how to use signals and slots properly in PyQt.
For threading, use QThread rather than threading.
Thread as it is better integrated with the Qt framework.
The second method using moveToThread is considered to be the most correct way to create new threads.
I cannot handle this kind of checking in the main thread because the infinite loop will down the GUI.
The seperate thread unfortunately wont work either, this is because you cannot access certain Qt elements outside of the Parent thread the textEdit.
If you define clearText to be a slot and connect it to a signal in your worker thread, the thread is signalling the main thread to call textEdit.
The first link I posted shows you how to define a signal trigger.
Just use pyqtSignal β€” Jun 26 '14 at 18:04 To add to user3419537 good answer.
A very quick threading example: from PyQt4.
Because I named the signal the same as a function it didn't know what to use.
Please see amended code above.
I don't have access to PyQt environment at the moment so cant test the code properly.
Provide details and share your research!

PyQt4 signals and slots A button click should do something. To do so, you must use signals and slots. If a user does an action such as clicking on a button, typing text in a box – the widget sends out a signal. Signals can be connected with a slot, that acts as a receiver and acts on it.

When a user takes an action β€” clicking on a button, selecting a value in a combo box, typing in a text box β€” the widget in question emits a signal.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.
