I want to make my application use dynamic unity quicklists. For building my application I am using C++ and the QtCreator IDE. When a menu action is triggered I want to be able to have access to a non-static function of my MainWindow class so as to be able to update the Graphical User Interface which can be accessed from inside 'normal' MainWindow's functions.

I have a function already implemented in cpp with prototype. MyFunction(int size, int ( callback)(UINT16* arg1, UINT16 arg2)); Second argument is a function pointer which must be implemented in java. How can i implement that function? Also how can i call MyFunction in JNI?

This is the #GObject based object that represents a menu item. It gets created the same on both the client and the server side and libdbusmenu-glib does the work of making this object model appear on both sides of DBus. Simple really, though through updates and people coming on and off the bus it can lead to lots of fun complex scenarios.

If you’re using JNI, you may wish to callback a java method asynchronously. For example event handling from a win32 message pump.

The aim of this JNI tutorial is to use the Java Native Interface JNI to call a pure java callback from a native C++ function. It is slightly more complicated that just calling a native function, but will better demonstrate some of the JNI functionality. We will be using the Visual C++ cl.exe without the IDE to compile the C++ DLL that will contain the JNI implementations. Leave any questions or problems as comments and I will endeavour to answer them.
