Set of all the keys currently depressed based on buffered input events.

Constructor & Destructor Documentation

Ogre::SDLInput::SDLInput  ) 
 

virtual Ogre::SDLInput::~SDLInput  )  [virtual]
 


Member Function Documentation

void Ogre::SDLInput::_grabMouse  )  [private]
 

void Ogre::SDLInput::_releaseMouse  )  [private]
 

void Ogre::InputReader::addCursorMoveListener MouseMotionListener c  )  [inherited]
 

Adds a mouse motion listener to the cursor object.

This keeps the Cursor object hidden.

void Ogre::SDLInput::capture  )  [virtual]
 

Captures the state of all the input devices.

Remarks:
This method captures the state of all input devices and stores it internally for use when the enquiry methods are next called. This is done to ensure that all input is captured at once and therefore combinations of input are not subject to time differences when methods are called.

Implements Ogre::InputReader.

void Ogre::InputReader::createKeyEvent int  id,
int  key
[protected, inherited]
 

void Ogre::InputReader::createMouseEvent int  id,
int  button
[protected, inherited]
 

Creates a MouseEvent that first gets processed by the cursor, then gets pushed on the queue.

char Ogre::InputReader::getKeyChar int  keyCode,

Initialise the input system.

Note:
Only keyboard and mouse currently implemented.
Parameters:
pWindow The window to capture input for
useKeyboard If true, keyboard input will be supported.
useMouse If true, mouse input will be supported.
useGameController If true, joysticks/gamepads will be supported.

Implements Ogre::InputReader.

virtual bool Ogre::InputReader::isKeyDown KeyCode  kc  )  const [virtual, inherited]
 

Determines if the specified key is currently depressed.

Note:
In immediate mode, this enquiry method uses the state of the keyboard at the last 'capture' call.

bool Ogre::SDLInput::isKeyDownImmediate KeyCode  kc  )  const [private, virtual]
 

Return whether a key is down in immediate mode.

Implements Ogre::InputReader.

void Ogre::InputReader::keyChanged int  key,

void Ogre::SDLInput::processBufferedMouse  )  [private]
 

void Ogre::InputReader::removeCursorMoveListener MouseMotionListener c  )  [inherited]

virtual void Ogre::InputReader::setBufferedInput bool  keys,
bool  mouse
[virtual, inherited]
 

Reimplemented in Ogre::Win32Input8.

void Ogre::SDLInput::setGrabMode GrabMode  mode  ) 
 

Sets how to grab the mouse.

Possible values for mode are GRAB_MOUSE_OVER or GRAB_MOUSE_BUTTON. The first will grab the mouse if the pointer is over the application window and the latter will wait for a mouse button click to aquire the mouse. Default is GRAB_MOUSE_CLICK.

Definition at line 64 of file OgreSDLInput.h.

References mGrabMode.

virtual void Ogre::InputReader::setMouseScale Real  scale  )  [virtual, inherited]
 

Set mouse scale factor.

Parameters:
scale The new mouse scale (The default on is around 0.001/0.002).

Definition at line 313 of file OgreInput.h.

References Ogre::Real.

void Ogre::InputReader::triggerMouseButton int  nMouseCode,
bool  mousePressed
[protected, inherited]
 

Creates mouse pressed, released, and clicked events.

void Ogre::InputReader::useBufferedInput EventQueue pEventQueue,
bool  keys = true,
bool  mouse = true
[inherited]
 

Tells the reader to use buffered input and update the passed in queue.

Remarks:
The default behaviour of the input reader is simply to capture the current state of the mouse / keyboard on demand. An alternative is to use buffered input where all events are registered on a queue.
