Show dialog after hide another

[Rúben Rodrigues <ruben_gr live com pt>]

Hi guys,


I have i problem when trying to hide a dialog and show another at the 
same moment.

I have a dialog that have an OK button that calls this function:

void on_button_Util_Firmware_Update_clicked(GtkButton *button, gpointer 
user_data)
{
     GtkLabel    *gLabel_Result;
     FILE        *fp;
     gchar        pcTmp[BUFSIZ];

     // Fecha a janela.
gtk_widget_hide(GTK_WIDGET(gtk_widget_get_toplevel(GTK_WIDGET(button))));

     // Mostra a janela de espera.
     gtk_widget_show(GTK_WIDGET(gtk_builder_get_object(builder, 
"Setup_Wait_dialog")));
     sleep(10);

  //**Running something inside

// Esconde a janela de espera.
     gtk_widget_hide(GTK_WIDGET(gtk_builder_get_object(builder, 
"Setup_Wait_dialog")));

}

As you can see this is a Waiting dialog to show the status of the 
process, but the problem is  that don't show the Setup_Wait_dialog and 
don't hides the first dialog. What's wrong?

Thanks
