Next question: how to create new instances?

constant LIB = open_dll("libgtk-3.so.0") 
constant  
 P = C_PTR, 
 I = C_INT 
  
integer init_rid = define_c_func(LIB,"gtk_init_check",{P,P},P)  
if init_rid < 1 or c_func(init_rid,{0,0})=0 then  
  crash("Failed to initialize GTK library!")  
end if  
 
class Window  
  public atom handle = c_func(define_c_func(LIB,"gtk_window_new",{I},P),{0}) 
  procedure show() 
    c_proc(define_c_proc(LIB,"gtk_widget_show",{P}),{handle}) 
  end procedure 
end class 
 
procedure main()  
c_proc(define_c_proc(LIB,"gtk_main",{}))  
end procedure  
 
Window w1 = new()  
Window w2 = new() 
 
? w1 ? w1.handle 
? w2 ? w2.handle -- same as w1 
 
w1.show()  
w2.show() -- already shown 
 
main() 

{"struct","Window",2,1} 
30917232 
{"struct","Window",2,2} 
30917232 

Both windows have the same "handle". How can I change my code so each call to new() will call the "gtk_window_new" function again to get a new unique handle?
