[Kde-bindings] Qyoto. How to declare and to pass a signal as method parameter?

[alex]

Hi. Please help me with signals.

I am trying to migrate code from C++ to C#. This is an example from Qt 
(Qt/4.8.2/examples/animation/animatedtiles/main.cpp)
In C++ has the following code:

class Button : public QGraphicsWidget
{
...
signals:
     void pressed();
...
}

Then a signal "pressed()" is passed as a parameter to the function 
rootState->addTransition

Button *ellipseButton = new Button(QPixmap(":/images/ellipse.png"), 
buttonParent);
QState *rootState = new QState;
QAbstractTransition *trans = rootState->addTransition(ellipseButton, 
SIGNAL(pressed()), ellipseState);

I can't understand how to write it to C#.

class Button: QGraphicsWidget
{
...
protected pressed() <-- ??? How to properly declare a signal?
...
}
At first I thought do not use signals, and instead use the C# events:
event EventHandler pressed;
But in any case, don't know that I need to pass to the function :(
rootState->addTransition(ellipseButton, SIGNAL("<--??? What to write 
here?"), ellipseState);

Please help me with a problem.

With best regards
