Enabling and disabling display elements

void enable ()
 Enable this display element: insert it into the linked list of instances, so it gets drawn to the display.
 
void disable ()
 Disable this display element: remove it from the linked list of instances, so it no longer gets drawn to the display.
 
bool isEnabled () const
 Check if this display element is enabled.
 
static void enable (DisplayElement *element)
 Enable this display element: insert it into the linked list of instances, so it gets drawn to the display.
 
static void enable (DisplayElement &element)
 Enable this display element: insert it into the linked list of instances, so it gets drawn to the display.
 
template<class U , size_t N>
static void enable (U(&array)[N])
 Enable this display element: insert it into the linked list of instances, so it gets drawn to the display.
 
static void disable (DisplayElement *element)
 Disable this display element: remove it from the linked list of instances, so it no longer gets drawn to the display.
 
static void disable (DisplayElement &element)
 Disable this display element: remove it from the linked list of instances, so it no longer gets drawn to the display.
 
template<class U , size_t N>
static void disable (U(&array)[N])
 Disable this display element: remove it from the linked list of instances, so it no longer gets drawn to the display.
