Hello, this is my first post, I'm from México and my english is not good, I hope you understand my posts, by the way, I'm a begginer in Gtk+.
Well, I have a probem, I 've wriiten a small program that lexically analize words, those are: getc, gets, getch & getchar. My program uses an automata algorythm with its transition table. I made a GUI with Gtk that uses a GtkEntry that receive the word to analize and a button with label 'Analizar', when I type a word and make 'click' in the button, the program ends and the console shows a message: 'Segment viotation', the program should generate a dialog window with the message: 'Cadena Aceptada' or 'Cadena No Reconocida'.
The porgram in console mode runs normally and make the things good.
The code is the following:
#include <gtk/gtk.h>
#include <stdio.h>
#include <string.h>
gint tabla[6][5] = {1,-1,-1,-1, 2,
-1, 3,-1,-1,-1,
-1,-1,-1,-1,-1,
-1,-1, 4,-1,-1,
-1,-1,-1, 5,-1,
-1,-1,-1,-1,-1};
gint Ei = 0, F[4] = {1,2,3,5};
gchar cadena[5] = {'c','h','a','r','s'};
gint salir(GtkWidget *win, gpointer dato)
{
g_print("Saliendo de la aplicación...\n");
gtk_main_quit();
return FALSE;
}
gint mueve(gint St, gchar cad)
{
int x;
for (x = 0; x < 5; x++)
if (cad == cadena[x])
return tabla[St][x];
return -1;
}
gint buscar(gint St)
{
int x;
for (x = 0; x < 4; x++)
if (St == F[x])
return 0;
return 1;
}
void lexico(GtkWidget *campo)
{
GtkWidget *otra_win, *mensaje, *ok, *box;
otra_win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(otra_win),"Resultado");
gtk_window_set_default_size(GTK_WINDOW(otra_win),200,80);
gtk_container_border_width(GTK_CONTAINER(otra_win),15);
ok = gtk_button_new_with_label("Hecho");
box = gtk_vbox_new(FALSE,10);
gchar *str, *res = '\0';
gint S = Ei, i = 0, tot;
strcpy(str,gtk_entry_get_text(GTK_ENTRY(campo)));
tot = strlen(str);
i = 3;
if (!strncmp("get",str,3))
while(i < tot)
{
if (S < 0)
break;
S = mueve(S, str[i]);
i++;
} if (!buscar(S))
res = "Cadena Aceptada";
else
res = "Cadena No Reconocida";
mensaje = gtk_label_new(res);
gtk_box_pack_start(GTK_BOX(box),mensaje,FALSE,FALSE,0);
gtk_box_pack_start(GTK_BOX(box),ok,FALSE,FALSE,0);
g_signal_connect_swapped(G_OBJECT(ok),"clicked",G_CALLBACK(gtk_widget_destroy),G_OBJECT(otra_win));
gtk_container_add(GTK_CONTAINER(otra_win),box);
gtk_widget_show_all(otra_win);
}
int main(int argc, char *argv[])
{
GtkWidget *win, *label, *entry, *btn_ok, *hbox, *vbox;
gtk_init(&argc,&argv);
win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(win),"Analizador Léxico");
gtk_container_border_width(GTK_CONTAINER(win),15);
g_signal_connect(G_OBJECT(win),"delete_event",G_CALLBACK(salir),NULL);
hbox = gtk_hbox_new(FALSE,5);
vbox = gtk_vbox_new(FALSE,10);
label = gtk_label_new("Cadena");
entry = gtk_entry_new();
btn_ok = gtk_button_new_with_label("Analizar");
gtk_box_pack_start(GTK_BOX(hbox),label,FALSE,FALSE,0);
gtk_box_pack_start(GTK_BOX(hbox),entry,FALSE,FALSE,0);
gtk_box_pack_start(GTK_BOX(vbox),hbox,FALSE,FALSE,0);
gtk_box_pack_start(GTK_BOX(vbox),btn_ok,FALSE,FALSE,0);
g_signal_connect_swapped(G_OBJECT(btn_ok),"clicked",G_CALLBACK(lexico),entry);
gtk_container_add(GTK_CONTAINER(win),vbox);
gtk_widget_show_all(win);
gtk_main();
return 0;
}
I used Gtk+ v.2.2.4, I hope you help me. Thanks
