Send data on a signal_button_press_event

[Iker Perez de Albeniz <ialbeniz cbt es>]

I'am creating DrawingAreas and i want to add an action when i clik on
them..

**********************************************************************

(*nDrawingArea).set_events(Gdk::BUTTON_PRESS_MASK);

(*nDrawingArea).signal_button_press_event
().connect(sigc::mem_fun(*this, &colorSelectorWindow::setColor1)); 


bool colorSelectorWindow::setColor1(GdkEventButton* event){
	
	int Color = 65535;
	std::ostringstream o;
	
	o << "00";
			for (int k=2*sizeof(int) - 7; k>=0; k--) {
            	o << "0123456789ABCDEF"[((Color/257 >> k*4) & 0xF)]; 
        	}
	o << "FF";
	m_ColorHex.set_text(o.str());
	aux_Color.set_rgb(0,Color,65535);
	m_SelectedColor.modify_bg(Gtk::STATE_NORMAL,
Gdk::Color(aux_Color));
	
return true;
}
****************************************************************************

The problem is that i want to send an int on the event so i have tried
this..

***********************************************************

(*nDrawingArea).signal_button_press_event
().connect(sigc::bind<int>( sigc::mem_fun(*this,
&colorSelectorWindow::setColor1), colour_p)); 

void colorSelectorWindow::setColor1(int Color){
	
std::ostringstream o;
	
o << "00";
for (int k=2*sizeof(int) - 7; k>=0; k--) {
     o << "0123456789ABCDEF"[((Color/257 >> k*4) & 0xF)]; 
 }
	o << "FF";
	m_ColorHex.set_text(o.str());
	aux_Color.set_rgb(0,Color,65535);
	m_SelectedColor.modify_bg(Gtk::STATE_NORMAL, Gdk::Color(aux_Color));
	
return true;
}
