The following example writes "Hello, World!" using signals and slots. First, we create a signal sig, a signal that takes no arguments and has a void return value.Next, we connect the hello function object to the signal using the connect method. Finally, use the signal sig like a function to call the slots, which in turns invokes HelloWorld::operator() to print "Hello, World!". PyQt/Sending Python values with signals and slots - Python ...
