EventCompressor< T > Class Template Reference

#include <events.h>

Public Types
typedef DisplayObject *(T::*	EventSenderCbType) (DisplayEvent *ev)
	Typedef for a event callback function pointer.

Public Member Functions
void	Active (bool val)
bool	Active ()
	EventCompressor (T *objectPtr, EventSenderCbType cb)
bool	CompressEvent (const DisplayEvent &ev)
void	SendAnyCompressedEvents ()
	Passes along the resulting compressed event to the target object's callback function.

Protected Attributes
MouseEvent	_lastCompressedEvent
	The result of event compression, i.e. what all the other events boiled down to.
bool	_lastEventWasCompressed
	If true, the event we're passing along was compressed.
EventSenderCbType	_handleCb
	The callback function that will process this event.
T *	_objectPtr
	The object containing the callback function.
bool	_sendingCompressed
	Flag set to avoid compressing an already compressed event (infinite loop).
bool	_active
	If active, events will be compressed, i.e. multiple MOUSE_DRAG will be boiled down to one equivalent MOUSE_DRAG.

EventCompressor()

EventCompressor ( T *  objectPtr, EventSenderCbType  cb  )

inline

Construct a new EventCompressor object to compress events for the given object.

Parameters

objectPtr	The object to receive compressed events, contains the callback function.
cb	The callback function to receive compressed events.

Member Function Documentation

Active() [1/2]

bool Active ( )

inline

Returns

The current active state of event compression.

Active() [2/2]

void Active ( bool  val )

inline

Set the current active state for event compression.

Parameters

val	The new active state to set.

CompressEvent()

bool CompressEvent ( const DisplayEvent &  ev )

inline

Caller should stop processing this event if returns true Caller MUST call SendAnyCompressedEvents() before drawing to make sure any saved events are processed.

Parameters

ev	The event to compress.

Returns

True if event was compressed.
