[Glade-users] problems with glade

[albert vorwireless net (Albert)]

Hi all, this is my first message in the list, excuse me for my poor
english.

Now I build my first project in glade. It is a button and a text_view. I
want read a text file using fgets and show in the text_view.

I paste de source:

----- interface.c ------------ 8< ------
#ifdef HAVE_CONFIG_H
#  include <config.h>
#endif

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <string.h>
#include <stdio.h>

#include <gdk/gdkkeysyms.h>
#include <gtk/gtk.h>

#include "callbacks.h"
#include "interface.h"
#include "support.h"

#define GLADE_HOOKUP_OBJECT(component,widget,name) \
  gtk_object_set_data_full (GTK_OBJECT (component), name, \
    gtk_widget_ref (widget), (GtkDestroyNotify) gtk_widget_unref)
#define GLADE_HOOKUP_OBJECT_NO_REF(component,widget,name) \
  gtk_object_set_data (GTK_OBJECT (component), name, widget)

GtkWidget*
create_tenes777 (void)
{
  GtkWidget *tenes777;
  GtkWidget *vbox2;
  GtkWidget *buto;
  GtkWidget *scrolledwindow1;
  GtkWidget *textbox;
  GtkTextBuffer *buffer;

  tenes777 = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_widget_set_usize (tenes777, 300, 300);
  gtk_window_set_title (GTK_WINDOW (tenes777), _("Hacklab Tenes777"));

  vbox2 = gtk_vbox_new (FALSE, 0);
  gtk_widget_show (vbox2);
  gtk_container_add (GTK_CONTAINER (tenes777), vbox2);

  buto = gtk_button_new_with_mnemonic (_("recollir"));
  gtk_widget_show (buto);
  gtk_box_pack_start (GTK_BOX (vbox2), buto, FALSE, FALSE, 0);

  scrolledwindow1 = gtk_scrolled_window_new (NULL, NULL);
  gtk_widget_show (scrolledwindow1);
  gtk_box_pack_start (GTK_BOX (vbox2), scrolledwindow1, TRUE, TRUE, 0);

// my code start here:

  FILE *correu;
  int a, i;
  char magatzem[1024];

  correu = fopen("/tmp/tenes777","r");
  textbox = gtk_text_view_new();
  buffer = gtk_text_buffer_new (NULL);
  while (!feof(correu)) {
  fgets(magatzem, 1000, correu);
  a++;
  if (strstr(magatzem, "[Tenes777]") != NULL) {
    gtk_text_buffer_set_text (buffer, magatzem, -1);
    gtk_text_view_set_buffer (GTK_TEXT_VIEW (textbox), buffer);
    gtk_widget_show (textbox);
    i++;
  }
 }
///------------end of my code----------------///

  gtk_container_add (GTK_CONTAINER (scrolledwindow1), textbox);

  gtk_signal_connect (GTK_OBJECT (buto), "clicked",
                      GTK_SIGNAL_FUNC (on_buto_clicked),
                      NULL);

  /* Store pointers to all widgets, for use by lookup_widget(). */
  GLADE_HOOKUP_OBJECT_NO_REF (tenes777, tenes777, "tenes777");
  GLADE_HOOKUP_OBJECT (tenes777, vbox2, "vbox2");
  GLADE_HOOKUP_OBJECT (tenes777, buto, "buto");
  GLADE_HOOKUP_OBJECT (tenes777, scrolledwindow1, "scrolledwindow1");

  GLADE_HOOKUP_OBJECT (tenes777, textbox, "textbox");

  return tenes777;
}

When execute the program, it returns:
