Error in <TQObject::CheckConnectArgs>: slot XX() does not exist

Hello ROOTers,

I am trying to make a GUI class which has a clickable button. But it does not work, while the code seems to be based on p390-391 of the user's guide v5.21.

$ root
root [0] TargetUSB::TEventViewer view
Error in <TQObject::CheckConnectArgs>: slot Play() does not exist

I created a dictionary according to this old thread which was found after googling. http://root.cern.ch/root/roottalk/roottalk02/0697.html

A small example is uploaded here. Could anyone help me in removing this problem, please? http://slac.stanford.edu/~oxon/tmp/TargetUSB.tgz

I am using ROOT 5.27.02 on OS X 10.6 and SL 5.

Regards,
