[paragui-users] Signals and Slots

[Dimitris Mexis]

clsStartUp::clsStartUp( struct GfxOptions & gfxOptions, PG_Widget * 
parent, PG_Rect r, char * windowtext ):
pgWindow( parent, r, windowtext) <---------Just the constructor, just to 
show you where it lies

this is my line that emits a signal...
{
rdoNation->sigClick.connect( slot( *this, &clsStartUp::handle_selectitem 
) );
   PG_RadioButton & rdm = rdoNation[0];
}

This is the slot...
bool clsStartUp::handle_selectitem( PG_Pointer clientdata )
{
   PG_RadioButton* b = (PG_RadioButton*)clientdata;
   int id = b->GetID();
   player->setNation( id );
}

Why doesn't it work? It gives me :

In the end....HOW can anyone connect a RADIOBUTTON or something that has 
clientdata to a slot!? Please do not send me back to the examples, 
because the signals and slot mechanisms are for....buttons(!) The only 
thing that I saw worth to investigate is building a MyClass, but is this 
the right way ? How could I? In the end is there anyone who used the 
radiobutton and clientdata?  Someone?
