QState addTransition doesn't work in c++/clr environment

Because of using dll, I changed Common Language Runtime Support in my QT project into Common Language Runtime Support (/clr).

i used: stateExploring->addTransition(ui.startExperiment, &QPushButton::clicked, stateRunning); to change from state "stateExploring" into "stateRunning" when button is clicked, it seems that this function doesn't work.

I tried connect a slot for button event function, it worked well ( it shows message box when button clicked)

for debugging, I changed into No Common language support, this function worked well.
