Thread: GTK signal question

Hi,

I seem to have a similar problem to this case:
c - char* in a gpointer sends a string in a strange encoding - Stack Overflow

I made recent_title a global variable as explained in the link. But I still get gibberish message. Parts of code:

gtk/xboard.h

Code:

extern GtkRecentInfo *recents_ptr[RECENTS_COUNT+1];
extern gchar recent_title[20];

gtk/xboard.c

Code:

GtkRecentInfo *recents_ptr[RECENTS_COUNT+1];
gchar recent_title[20];

[...]
void show_message_dialog(const gchar * const message)
{

    GtkWidget*  dialog = gtk_message_dialog_new (GTK_WINDOW(mainwindow),
                                     GTK_DIALOG_DESTROY_WITH_PARENT,
                                     GTK_MESSAGE_INFO,
                                     GTK_BUTTONS_CLOSE,
                                     "Message: %s",
                                     message);

    /* Destroy the dialog when the user responds to it (e.g. clicks a button) */
    g_signal_connect_swapped (dialog, "response",
                              G_CALLBACK (gtk_widget_destroy),
                              dialog);
    gtk_widget_show_all (dialog);
    return;
}
void show_message_dialog_event(GtkWidget*label_1,gpointer message)
{
    show_message_dialog(message);
    return;
}

gtk/xoptions.c

Code:

[...]
    produce_recent_items();
        for(i=0; i<RECENTS_COUNT && recents_ptr[i] ; i++)
        {
            GtkRecentInfo *recent_wid=recents_ptr[i]; 
                        
            g_stpcpy(recent_title,"TTT3_\n");
                show_message_dialog(recent_title); // Works OK

                const gchar *fn;
                fn=gtk_recent_info_get_uri(recent_wid);
                //show_message_dialog(fn); // TODO broken
                g_signal_connect(G_OBJECT(recent_wid),"activate"
                ,G_CALLBACK(show_message_dialog_event),(gpointer)recent_title);// recent_title shows gibberish
        }

What can I do ?
