GUI Locks with gthreads

[Miraclesoa Miraclesoa <miraclesoa yahoo es>]

Hi all

I have a problem with my GUI and gthreads.

I have two threads: one reads data from the database
and puts them into a buffer. Other reads the buffer
and updates some gtklabels.

My application (GUI) locks after a few minutes.  I do
not know what I am doing wrong.

I put some of my code:

//Here I created the threads
g_thread_create(consultar_valores_ciclo,NULL,FALSE,NULL);
g_thread_create(actualizar_valores_ciclo,NULL,FALSE,NULL);

//Here is the consultar_valores_ciclo function
static void consultar_valores_ciclo()
{
        GThread* self=NULL;
        gchar *aux1=NULL;
        gint mic;
        while (1)
        {
                g_mutex_lock(gmx);
                if (zfin==0)
                {
                                if (gmx != NULL)
                                {
                                        consultar_valores();    //reads data from db
                                        g_timer_reset(zparo);
                                        g_timer_start(zparo);
                                        zini=g_timer_elapsed(zparo,NULL);
                                        while(zini==0 && zfin==0)
                                        {
                                                zini=g_timer_elapsed(zparo,NULL);
                                        }
                                        g_timer_stop(zparo);
                                        zini=0;
                                        if(zfin==1)
                                        {
                                                self = g_thread_self();
                                                g_mutex_unlock(gmx);
                                                g_thread_exit(self);
                                        }
                                }
                }
                if(zfin==1)
                {
                        self = g_thread_self();
                        g_mutex_unlock(gmx);
                        g_thread_exit(self);
                }
                g_mutex_unlock(gmx);
        }
}


//Here is the actualizar_valores_ciclo function
static void actualizar_valores_ciclo()
{
        GThread* self=NULL;
        gchar *aux1=NULL;
        gint mic=0;
        while (1)
        {
                g_mutex_lock(gmx);
                if (zfin==0)
                {
                                if (gmx != NULL)
                                {
                                        actualizar_valores();
                                        g_timer_reset(zparo);
                                        g_timer_start(zparo);
                                        zini=g_timer_elapsed(zparo,NULL);
                                        while(zini==0 && zfin==0)
                                        {
                                                zini=g_timer_elapsed(zparo,NULL);
                                        }
                                        g_timer_stop(zparo);
                                        zini=0;
                                        if(zfin==1)
                                        {
                                                self = g_thread_self();
                                                g_mutex_unlock(gmx);
                                                g_thread_exit(self);
                                        }
                                }
                }
                if(zfin==1)
                {
                        self = g_thread_self();
                        g_mutex_unlock(gmx);
                        g_thread_exit(self);
                }
                g_mutex_unlock(gmx);
        }
}


I also put the code :

  gdk_threads_enter();
  gtk_main();
  gdk_threads_leave();

I also put this code :

 gdk_threads_enter();
        label =
lookup_widget(GTK_WIDGET(toplevel),"label_name");
        gtk_label_set_text(GTK_LABEL(label), "whatever");
  gdk_threads_leave();



Thanks in advance and best regards
