you made me confused about what you need - you can have many classes that emit the very same name signal (like readyread - in qtcpsocket, qabstractsocket, qudpsocket and so on...) but you make the difference between them when you use connect... - you have to select the sender.. so how can it be any confusions at all?? Qt.ConnectionType If the signal is emitted from the thread in which the receiving object lives, the slot is invoked directly, as with Qt::DirectConnection ; otherwise the signal is queued, as with Qt::QueuedConnection . static Qt.ConnectionType: BlockingQueuedConnection Same as QueuedConnection , except that the current thread blocks until the slot has been ... c++ - Using Qt signals and slots vs calling a method ... Using Qt signals and slots vs calling a method directly. Ask Question 10. 2. ... If you use a Qt signal, now any other object can connect to receive the event whenever it occurs. ...

Checking the Qt signal slot connect calls at runtime is a worry for me. I should be possible to run a static check of the connect statements.I want to use a signals/slots library in a project that doesn't use QT. I have pretty basic requirements: Connect two functions with any number of parameters.

Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part thatThe same is true whenever you do a system call in a slot; or indirectly call more than ten functions. On an i586-500, you can emit around 2,000,000... How Qt Signals and Slots Work The Qt signals/slots and property system are based on the ability to introspect the objects at runtime. Introspection means being able to list the methodsThe first thing Qt does when doing a connection is to find out the index of the signal and the slot. Qt will look up in the string tables of the meta object to...

If the receiver is in the same thread, the event will be processed later, as the event loop iterates. The event will be deleted right after being processed in the thread that processes it. An event posted using a QueuedConnection is a QMetaCallEvent. When processed, that event will call the slot the same way we call them for direct connections.

Support for Signals and Slots — PyQt 5.10.1 Reference Guide Support for Signals and Slots¶ One of the key features of Qt is its use of signals and slots to communicate between objects.
