Traditional syntax: SIGNAL and SLOT() QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton. The connect method has a non python-friendly syntax. QThreads general usage - Qt Wiki While this Worker class doesn't do anything special, it nevertheless contains all the required elements.

20 ways to debug Qt signals and slots | Sam Dutton’s blog Below are some suggestions for troubleshooting signals and slots in the Qt C++ library. 1. Check for compiler warnings about non-existent signals and/or slots. 2. Use break points or qDebug to check that signal and slot code is definitely reached: – the connect statement – code where the signal is fired – the slot code. 3. Signals and Slots in Qt5 - Woboq As you might have seen in the previous example, the slot was just declared as public and not as slot. Qt will indeed call directly the function pointer of the slot, and will not need moc introspection anymore.

Qt signals and slots in different classes - Stack Overflow Qt signals and slots in different classes. ... Then, if I call that method from class X, signal is emitted, and slot is executed.

This pseudo-code tries to explain what I want: [solved] Qt Signal/Slots in one class but emitted from ... So the GUI class defines slots and signals, the signals are emitted in the implemented interface functions. The signals and slots are connected using: @"connect(this, SIGNAL(xyz), this SLOT(xyz));"@ I think the problem is that the intface functions that emit the signals are running in thread a but the GUI runs in thread b.
