Additional Inherited Members
Static Public Member Functions inherited from GUIEngine::Widget
static void	resetIDCounters ()
	When switching to a new screen, this function will be called to reset ID counters (so we start again from ID 0, and don't grow to big numbers)

static int	getNewID ()
	Provides a new unique ID on each call, for widgets that can be focused.

static int	getNewNoFocusID ()
	Provides a new unique ID on each call, for widgets that can not be focused.

static bool	isFocusableId (const int id)
	get whether the given ID represents an ID of a widget that can be focused

Public Attributes inherited from GUIEngine::Widget
Widget *	m_event_handler
	This is set to NULL by default; set to something else in a widget to mean that events happening on this widget should also be passed to m_event_handler->transmitEvent, which is usually the parent analysing events from its children.

bool	m_supports_multiplayer
	Whether this widget supports multiplayer interaction (i.e.

int	m_tab_down_root
	Instead of searching for widget IDs smaller/greater than that of this object, navigation through widgets will start from these IDs (if they are set).

int	m_tab_up_root
	Instead of searching for widget IDs smaller/greater than that of this object, navigation through widgets will start from these IDs (if they are set).

int	m_x
	Coordinates of the widget once added (the difference between those x/h and PROP_WIDTH/PROP_HEIGHT is that the props are read in raw form from the XML file; PROP_WIDTH can then be e.g.

int	m_y

int	m_w

int	m_h

bool	m_show_bounding_box
	Whether to show a bounding box around this widget (used for sections)

bool	m_is_bounding_box_round
	Only used if m_show_bounding_box is true.

int	m_reserved_id
	Used in two cases : 1) For 'placeholder' divisions; at the time the layout is created, there is nothing to place there yet, but we know there eventually will.
