c - Print variable in GTK+ assistant -


i want ask user in gtk+ assistant name, save name in global variable , use variable in same assistant on different site. problem assistant completly created , changes on new sites have no effect.

example: initialisize global variable "name" "empty". now, assistant create sites displays first site. user writes down name in "entryfield" , variable "name" contains name. assistant displays second site should contain users name, displays string "empty".

i need "refresh" created entry new variable. sorry bad english, hope can explain problem little bit. :)

complete sample code:

#include <gtk/gtk.h> #include <string.h>  static void entry_changed    (gtkeditable*, gtkassistant*); static void assistant_cancel (gtkassistant*, gpointer); static void assistant_close  (gtkassistant*, gpointer);  char *name = "empty";  typedef struct {   gtkwidget *widget;   gint index;   const gchar *title;   gtkassistantpagetype type;   gboolean complete; } pageinfo;  int main (int argc,           char *argv[]) {   gtkwidget *assistant, *entry, *label;   guint i;   pageinfo page[5] = {     { null, -1, "introduction",           gtk_assistant_page_intro,    true},     { null, -1, null,                     gtk_assistant_page_content,  false},     { null, -1, null,                     gtk_assistant_page_content,  true},     { null, -1, "confirmation",           gtk_assistant_page_confirm,  true},   };    gtk_init (&argc, &argv);    /* create new assistant widget no pages. */   assistant = gtk_assistant_new ();   gtk_widget_set_size_request (assistant, 450, 300);   gtk_window_set_title (gtk_window (assistant), "gtkassistant example");   g_signal_connect (g_object (assistant), "destroy",                     g_callback (gtk_main_quit), null);    page[0].widget = gtk_label_new ("this example of gtkassistant. by\n"\                                   "clicking forward button, can continue\n"\                                   "to next section!");   page[1].widget = gtk_hbox_new (false, 5);   page[2].widget = gtk_entry_new();   page[3].widget = gtk_label_new ("finish!");    /* create necessary widgets second page. */   label = gtk_label_new ("your name: ");   entry = gtk_entry_new ();   gtk_box_pack_start (gtk_box (page[1].widget), label, false, false, 5);   gtk_box_pack_start (gtk_box (page[1].widget), entry, false, false, 5);    gtk_entry_set_text(gtk_entry(page[2].widget), name);    /* add 4 pages gtkassistant dialog. */   (i = 0; < 4; i++)   {     page[i].index = gtk_assistant_append_page (gtk_assistant (assistant),                                                page[i].widget);     gtk_assistant_set_page_title (gtk_assistant (assistant),                                   page[i].widget, page[i].title);     gtk_assistant_set_page_type (gtk_assistant (assistant),                                   page[i].widget, page[i].type);      /* set introduction , conclusion pages complete can      * incremented or closed. */     gtk_assistant_set_page_complete (gtk_assistant (assistant),                                      page[i].widget, page[i].complete);   }    /* update whether pages 2 through 4 complete based upon whether there    * text in gtkentry, check button active, or progress bar    * filled. */   g_signal_connect (g_object (entry), "changed",                     g_callback (entry_changed), (gpointer) assistant);   g_signal_connect (g_object (assistant), "cancel",                     g_callback (assistant_cancel), null);   g_signal_connect (g_object (assistant), "close",                     g_callback (assistant_close), null);   gtk_widget_show_all (assistant);   gtk_main ();   return 0; }  /* if there text in gtkentry, set page complete. otherwise,  * stop user progressing next page. */ static void entry_changed (gtkeditable *entry,                gtkassistant *assistant) {   const gchar *text = gtk_entry_get_text (gtk_entry (entry));   gint num = gtk_assistant_get_current_page (assistant);   gtkwidget *page = gtk_assistant_get_nth_page (assistant, num);   gtk_assistant_set_page_complete (assistant, page, (strlen (text) > 0));    name = g_strdup(gtk_entry_get_text(gtk_entry(entry))); }  /* if dialog cancelled, delete memory , clean after  * assistant structure. */ static void assistant_cancel (gtkassistant *assistant,                   gpointer data) {   gtk_widget_destroy (gtk_widget (assistant)); }  /* function apply changes , destroy assistant. */ static void assistant_close (gtkassistant *assistant,                  gpointer data) {   g_print ("you apply changes now!\n");   gtk_widget_destroy (gtk_widget (assistant)); }

in entry_changed, have call gtk_entry_set_text(gtk_entry(page[2].widget), name); again, set entry text once, thing matters. otherwise default value set when setting 3rd page sticks.
