![]() It turns out that C++ did not support callbacks in a very comfortable way until C++11, so easy to handle solutions are relatively new, and not easy to find on the World Wide Web. So, I turned to the World Wide Web, and tried to find that one good solution. How hard could that be? Well, hard enough. The idea is to provide the objects of the native classes with a pointer or reference to the method in the code behind, so they can invoke that method and thus update the log. The XAML user interface has a method in its C++ code behind class that updates a TextBlock, and thus may inform the user about significant events in the program. I wanted native C++ classes to report status updates to a XAML user interface. It is not that I invented these techniques, but it seems helpful to spread the good word. In this blog post we will see a few ways to do it well, and also mention deprecated facilities. Using a class member function as a callback is a possible source of confusion in C++, not in the least because C++11 brings considerable changes at this point.
