void MultiStateDisplay::Display::addExtensionDisplay ( CVExtensionDisplay * cvdisplay )

Adds an extension display to visualize a computer vision extension.

Parameters

cvdisplay extension to add

bool MultiStateDisplay::Display::calibrationInProgress ( )

Check if calibration is in progress.

Returns: true if calibration is in progress

void MultiStateDisplay::Display::destroy ( )

Deletes all resources, basically opposite of init().

May need valid OpenGL context.

void MultiStateDisplay::Display::init ( MultiTouch::Screen * )

Initialize the display.

This method must be called before any of the other methods.

void MultiStateDisplay::Display::initializeGL ( Luminous::RenderContext & r )

Initialize the OpenGL resources.This function is thread-safe.

Parameters

r	current render context

bool MultiStateDisplay::Display::keyPressEvent ( const Radiant::KeyEvent & event )

Processes a key press event.

Parameters

event event information

Returns: true if the event was consumed

bool MultiStateDisplay::Display::keyReleaseEvent ( const Radiant::KeyEvent & event )

Processes a key release event.

Parameters

event event information

Returns: true if the event was consumed

bool MultiStateDisplay::Display::mouseMoveEvent ( const Radiant::MouseEvent & event )

Processes a mouse move event.

Parameters

event event information

Returns: true if the event was consumed

bool MultiStateDisplay::Display::mousePressEvent ( const Radiant::MouseEvent & event )

Processes a mouse press event.

Parameters

event event information

Returns: true if the event was consumed

bool MultiStateDisplay::Display::mouseReleaseEvent ( const Radiant::MouseEvent & event )

Processes a mouse release event.

Parameters

event event information

Returns: true if the event was consumed

bool MultiStateDisplay::Display::mouseWheelEvent ( const Radiant::MouseEvent & event )

Parameters

event event information

Returns: true if the event was consumed

void MultiStateDisplay::Display::paintGL ( Luminous::RenderContext & r )

Paint the display using OpenGL Before calling this method the system should have set the OpenGL matrices to orthonormal 2D projection (gluOrtho2D), so that the origin is in the top-left corner of the graphics window.

This function is thread-safe in the sense that several threads can execute it at the same time. How-ever, other function calls must not be executed at the same time.

Parameters

r	current render context

bool MultiStateDisplay::Display::saveSettings ( ) const

Check if the settings should be saved.

This function can be used to check if the settings should be saved when the application quits.

Returns: true if the settings should be saved

void MultiStateDisplay::Display::saveToEEPROM ( )

Save the tracker configuration to device EEPROM.

Does nothing on hardware other than MT467.

void MultiStateDisplay::Display::saveToFile ( const QString & filename = "" )

Save the tracker configuration to a file.

Saves the tracker configuration to the given filename. If the filename is empty, the configuration is saved to the file defined by Merge.

Parameters

filename filename to save to

bool MultiStateDisplay::Display::timeToQuit ( )

Query the display for quit-command.

Returns: true if the quit command has been sent

void MultiStateDisplay::Display::update ( )

Update information from the tracker.

This method should be called before calling paintGL. It is

usually called from the application main thread, but it can also be caled from anywhere.

void MultiStateDisplay::Display::updateGeometryAutomatically ( bool automatic )

Make the display move/resize with mouse control By default the display can be dragged around (which happens automatically).

This feature can be disabled by using this function, argument "false". Disabling might be useful, if you set the geometry of the display yourself.

Parameters

automatic toggle to enable display move/resize
