Signals and Slots. PySide and PyQt are Python bindings to the Qt GUI and application framework. One killer feature of Qt is the signal & slot system, which is a way for widgets and objects to communicate events to one another. An object in Qt can send a signal to other subscribed objects. Signals are used to inform other objects that an event ... QThread — PySide 1.2.1 documentation However, you are free to connect the Worker’s slots to any signal, from any object, in any thread. It is safe to connect signals and slots across different threads, thanks to a mechanism called queued connections. Another way to make code run in a separate thread, is to subclass PySide.QtCore.QThread and reimplement PySide.QtCore.QThread.run ... Qt — PySide v1.0.7 documentation The slot is invoked immediately, when the signal is emitted. Qt.QueuedConnection: The slot is invoked when control returns to the event loop of the receiver’s thread. The slot is executed in the receiver’s thread. Qt.BlockingQueuedConnection: Same as QueuedConnection, except the current thread blocks until the slot returns. This connection ...

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 ... PySide Signals not being sent to Slot, from QThread object. I'm working with a multi-threading application, where a worker thread gets created, that emits a signal. After creating the thread, I connect the signal with an object slot, that will perform some action. The problem, is the object slot, is not called, can someone help to figure out what's wrong ? PySide: Connecting Multiple Widgets to the Same Slot - The ... As I learn PyQt and PySide, I am writing some tutorials to help my fellow travelers. Today we’ll be looking at how to connect multiple widgets to the same slot. In other words, we’ll be binding the widgets signals (basically events) to slots (i.e. callables like functions, methods) which are better known as “event handlers”. … Tkinter and PySide side-by-side - GitHub Pages
