Show a label with a message...

[Jose Luis Alarcon <jlalarcon tiggerfan com>]

  Hi gtk-list.

  I am very newbie in graphical programming. I have a short and simple program
based in the Gale-Main Tutorial examples, but something must be wrong, cos it don't
work like i wait. this is my program:

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

/*
 * Using GTK.
 */

#include <gtk/gtk.h>

void salute();
void salute_hide();

GtkWidget *ventana;
GtkWidget *caja1;
GtkWidget *caja2;
GtkWidget *caja3;
GtkWidget *message;
GtkWidget *boton1;
GtkWidget *boton2;

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

	caja1 = gtk_hbox_new(TRUE, 0);
	caja2 = gtk_hbox_new(TRUE, 0);
	caja3 = gtk_vbox_new(TRUE, 0);
	gtk_box_pack_start(GTK_BOX(caja3), caja1, TRUE, TRUE, 0);
	gtk_box_pack_start(GTK_BOX(caja3), caja2, FALSE, FALSE, 0);
	gtk_widget_show(caja1);
	gtk_widget_show(caja2);

	message = gtk_label_new(" ");
	gtk_box_pack_start(GTK_BOX(caja1), message, TRUE, TRUE, 0);
	gtk_widget_show(message);

	boton1 = gtk_button_new_with_label("Show");
  gtk_signal_connect (GTK_OBJECT (boton1), "clicked", GTK_SIGNAL_FUNC (salute), NULL);
    
	boton2 = gtk_button_new_with_label("Hide");
  gtk_signal_connect (GTK_OBJECT (boton2), "clicked", GTK_SIGNAL_FUNC (salute_hide), NULL);

	gtk_box_pack_start(GTK_BOX(caja2), boton1, TRUE, FALSE, 0);
	gtk_box_pack_start(GTK_BOX(caja2), boton2, TRUE, FALSE, 0);
	gtk_widget_show(boton1);
	gtk_widget_show(boton2);

    ventana = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_show(ventana);

	gtk_container_add(GTK_CONTAINER(ventana), caja3);
	gtk_widget_show(caja3);

    gtk_main();

    return 0;
}

void salute (GtkWidget *widget, gpointer data)
{
  message = gtk_label_new("This is GTK programming.");
}

void salute_hide (GtkWidget *widget, gpointer data)
{
  message = gtk_label_new(" ");
}

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

  I'm trying show a label with a message when i click "Show" button, and hide
this label when button "Hide" is clicked.

  Anybody give me a hint?, please. my idea is that i am doing a bad use of
gtk_label_new() or gtk_signal_connect() functions, but......

  Thanks very much, in advance.

  Regards.

  Jose.
