add items to toolbar

[Hairy_Palms]

im writing a program, using GTK, mainly as a learning exercise, im trying to create a toolbar and add items to it, but im having problems with the code,

GtkWidget *label;
	GtkWidget *piccy;
	GtkWidget *holder;
	GtkWidget *eventbox;
	GtkWidget *dropdown;
	GtkWidget *dropdownbutton;

dropdown = gtk_toolbar_new (); 
dropdownbutton = gtk_tool_item_new();
label = gtk_label_new ("Menu");
gtk_toolbar_insert (dropdown, dropdownbutton, 0);
gtk_container_add (GTK_CONTAINER (dropdownbutton), label);

when compiling it, i get a warning

my_applet.c:67: warning: passing argument 1 of ‘gtk_toolbar_insert’ from incompatible pointer type
my_applet.c:67: warning: passing argument 2 of ‘gtk_toolbar_insert’ from incompatible pointer type

which refers to the lines above, can anyone tell me what im doing wrong?

you need to cast it using GTK_TOOLBAR(dropdown)
