Detailed Description

The EventManager provides user input events to the client code. In addition, it keeps track of the state of various input devices, like keys, mouse position, and buttons.

Member Enumeration Documentation

anonymous enum

anonymous enum

Enumerator
kEventManPriority	Priority of the event manager. For now, it is lowest since it eats all events. This might be changed in the future though.
kEventRecorderPriority	Priority of the event recorder. It must go after the event manager in order to record events generated by it.
kEventRemapperPriority	Priority of the remap dialog. It must go first to capture all the events before they are consumed by other observers.

Member Function Documentation

init()

virtual void Common::EventManager::init ( )

inlinevirtual

Note

Called after graphics system has been set up.

Reimplemented in DefaultEventManager.

pollEvent()

virtual bool Common::EventManager::pollEvent ( Event &  event )

pure virtual

Get the next event in the event queue.

Parameters

event

Point to an Event struct, which will be filled with the event data.

Return values

true	If an event was retrieved.

Implemented in DefaultEventManager, and DSEventManager.

pushEvent()

virtual void Common::EventManager::pushEvent ( const Event &  event )

pure virtual

Push a "fake" event into the event queue.

Implemented in DefaultEventManager.

purgeMouseEvents()

virtual void Common::EventManager::purgeMouseEvents ( )

pure virtual

Purge all unprocessed mouse events already in the event queue.

Implemented in DefaultEventManager.

purgeKeyboardEvents()

virtual void Common::EventManager::purgeKeyboardEvents ( )

pure virtual

Purge all unprocessed keyboard events already in the event queue.

Implemented in DefaultEventManager.

getMousePos()

virtual Point Common::EventManager::getMousePos ( ) const

pure virtual

Return the current mouse position.

Implemented in DefaultEventManager.

getButtonState()

virtual int Common::EventManager::getButtonState ( ) const

pure virtual

Return a bitmask with the button states:

• bit 0: left button up=0, down=1
• bit 1: right button up=0, down=1

Implemented in DefaultEventManager.

getModifierState()

virtual int Common::EventManager::getModifierState ( ) const

pure virtual

pure virtual

Whether to return to the launcher.

Implemented in DefaultEventManager.

resetReturnToLauncher()

virtual void Common::EventManager::resetReturnToLauncher ( )
