A few months ago I wrote about passing extra arguments to slots in PyQt.Here, I want to briefly discuss how the same effect can be achieved with Qt itself. C++ is not as dynamic as Python, so Python's approaches of using lambda or functools.partial won't work .Fortunately, the Qt folks provided a solution that can make passing extra arguments to slots relatively simple.

The old method allows you to connect that slot to a signal that does not have arguments. But I cannot know with template code if a function has default arguments or not. So this feature is disabled. There was an implementation that falls back to the old method if there are more arguments in the slot than in the signal. c++ - Pass multiple arguments to slot - Stack Overflow We need to pass two arguments to a slot. I want to use one slot for two buttons, and one of the buttons will be used for adding, and the other one for subtracting.

Though the functionality of QtSignalForwarder can be mostly achieved in Qt 5 using the new signal/slot syntax, this may be useful for creating code which can work with either version or for porting.
