You should pass a widget pointer to this.

I was reading the code to check for the callbacks of the Bonobo
component but I didn't found them.

I also tryied to find the menu dialog creation invocation and also was
unable to found it. Well, I'm doing it quite quickly because I'm a bit
busy so may be I'm missing something.

Can you change the dialog creation signature to something like this ?
GtkWidget* create_dialog (PanelApplet* applet, int type, char * message)

Then you can - on dialog construction - use the functions:

BonoboUIComponent* 
panel_applet_get_popup_component  (PanelApplet *applet);

void        
bonobo_ui_component_freeze      (BonoboUIComponent *component,
                                CORBA_Environment *opt_ev);

And on destruction:

void        
bonobo_ui_component_thaw        (BonoboUIComponent *component,
                                 CORBA_Environment *opt_ev);


I suppose it should fix your problem.

This won't work.
