I've toyed with QT connections trying to create anonymous function when connecting a slot to a signal. For instance, I am trying to do the following:
So far so good, but sometime I find it cumbersome to define all the slots. Create a declaration, a definition, etc…
Connecting in Qt 5. There are several ways to connect a signal in Qt 5. Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget). Qt's signal and slot mechanism makes sure that if the signal is connected to a slot, the slot is automatically called with the signal's parameters. One signal can be connected to as many slots as needed. If more than one slot is connected, they are called when the signal is emitted one after another in the same order they were connected.
I would like to declare the body right there! Here's what I would like to do using std::function or a c++ lambda:
I've achieved that by creating a global object named _Q which is responsible to maintained the QT meta object information about all connection that needs to be called.

The idea here is that we maintain the QMetaObject needed to dispatch the call, when qt_metacall is called, to the proper anonymous functions. The magic is done in FillMetaStructs() to maintain the meta object structure each time a new connection is made when Call(..) is called.
