Help: Registering C++ Callback

["Jay J. Williams" <jjw ece nwu edu>]

Hi,

I'm having some problems using gtk+1.0.5 with g++.  I'm trying to register 
C++ callback functions within my code.  When I compile the program I get
the following warning for all the callbacks I register with 
gtk_signal_connect:

	warning: converting from `int (KevVideo::*)(_GtkWidget *,
		_GdkEvent *,void *)' to `void(*)()'

All of the c++ callbacks have the following prototype,

gint KevVideo::CB_widgetName(GtkWidget *widget,GdkEvent *event,
	gpointer data);

My program seems to run; the callbacks routines are called.  However, the
callback functions produce incorrect results when they accessing the
class's data members:( Does this appear to be an error on my part or is
there something special I should be doing in order to use C++ callbacks
with gtk+?


Cheers,
Jay
