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
Widgetm_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.
 
std::map< Property, std::string > m_properties
 A map that holds values for all specified widget properties (in the XML file)
