it worked.

Here is the code:

#include<gtk/gtk.h>
#include<vte/vte.h>
#include<stdio.h>

void
fork_done(VteTerminal *vte, gpointer udata)
{
	printf("Process died!!\n");
}

gboolean
window_deleted( GtkWidget *w, GdkEvent *ev, gpointer data)
{
	GtkWidget *vte = (GtkWidget*)data;
	char *text = "\n";

	printf("Finish command\n");
	vte_terminal_feed_child(VTE_TERMINAL(vte), text, strlen(text));

	gtk_widget_hide_all(w);

	return TRUE;
}

int main(int argc, char* argv[])
{
	char *params[] = {"/bin/sh", "-c", "ls -l ~/;read",NULL};
	char *env[] = {"PATH=/usr/bin:/bin:./usr/local/bin:/bin", NULL};
	int child;

	gtk_init(&argc, &argv);

	GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
	GtkWidget *table = gtk_table_new (1, 1, TRUE);
	GtkWidget *vte1 = vte_terminal_new ();

	gtk_signal_connect(GTK_OBJECT(vte1), "child-exited",
G_CALLBACK(fork_done), NULL);
	gtk_signal_connect(G_OBJECT(window), "delete_event",
G_CALLBACK(window_deleted), vte1);
	gtk_table_attach_defaults (table, GTK_WIDGET(vte1), 0, 1, 0, 1);
	gtk_container_add (window, table);
	gtk_widget_show_all (window);

	child = vte_terminal_fork_command (VTE_TERMINAL(vte1), "sh", params,
env, "~/", FALSE, FALSE, FALSE);
	printf("Child: %d\n", child);

	gtk_main ();

	return 0;
}
