[Glade-users] GtkCheckButton signal toggled not connected

[mferrero at reer.it (Manuel Ferrero)]

I draw a GtkCheckButton in my application and in its signal tab I wrote 
dummy_callback as signal callback for the toggled event.
In my code I call gtk_builder_connect_signals to automatically connect 
all the signals to the callbacks.
All my other callbacks works as expected, but if I click on the checkbox 
to change its state the dummy_callback isn't executed.
Where am I wrong?

I compile in a Win32 environment with MinGW gcc, passing the following 
parameters: -mms-bitfields `pkg-config --cflags gtk+-win32-2.0 
gmodule-2.0` `pkg-config --libs gtk+-win32-2.0 gmodule-2.0`

GTK+ 2.24.8
Glade 3.8.1
Windows XP
mingw32-gcc 4.6.2


I enclose the checkbox part of the glade file and the callback code.

// struct for callback data
typedef struct _ChData ChData;

struct _ChData
{
GtkWidget *window1;
GtkWidget *checkbutton1;
};

ChData *data;
data = g_slice_new(ChData);


// connects all the signals
gtk_builder_connect_signals(builder_handler, data);


// callback for the checkbox toggled event
G_MODULE_EXPORT void dummy_callback(GtkWidget *widget, ChData *data)
{
     guint dummy1;
     guint dummy2;

     dummy1 = 0;
     dummy2 = 0;
     dummy1++;
     dummy2++;
}   // dummy_callback
