Constructor & Destructor Documentation

Eaagles::BasicGL::GlutDisplay::GlutDisplay ( )

Member Function Documentation

int Eaagles::BasicGL::GlutDisplay::createWindow ( )

int Eaagles::BasicGL::GlutDisplay::getWindowId ( ) const [inline]

Returns winId (the window id).

bool Eaagles::BasicGL::GlutDisplay::isWindowId ( const int id ) const [inline]

Returns true if id == winId (the active window), else false.

unsigned int Eaagles::BasicGL::GlutDisplay::getIdleSleepTime ( ) const [inline]

Returns the idle callback's sleep time.

bool Eaagles::BasicGL::GlutDisplay::setIdleSleepTime ( const unsigned int ms ) [virtual]

Sets the idle callback's sleep time.

void Eaagles::BasicGL::GlutDisplay::swapbuffers ( ) [virtual]

Calls the function glutSwapBuffers().

Reimplemented from Eaagles::BasicGL::LcDisplay.

void Eaagles::BasicGL::GlutDisplay::configureIt ( ) [virtual]

Configures the display.

void Eaagles::BasicGL::GlutDisplay::mouseEvent	(	const int	button,
		const int	state,
		const int	x,
		const int	y
	)			`[virtual]`

Event function for graphic selection for LcComponent interface.

Reimplemented from Eaagles::BasicGL::LcDisplay.

void Eaagles::BasicGL::GlutDisplay::passiveMotionEvent	(	const int	x,
		const int	y
	)			`[virtual]`

This is an passive mouse motion call back event function for the LcComponent interface.

void Eaagles::BasicGL::GlutDisplay::mouseMotionEvent	(	const int	x,
		const int	y
	)			`[virtual]`

Mouse motion event with either key pressed.

void Eaagles::BasicGL::GlutDisplay::reset ( ) [virtual]

Resets the parameters.

Reimplemented from Eaagles::BasicGL::LcDisplay.

bool Eaagles::BasicGL::GlutDisplay::setSlotFullScreen ( const Basic::LcNumber *const msg )

Slot table function for setting full screen.

bool Eaagles::BasicGL::GlutDisplay::setSlotIdleSleepTime ( const Basic::LcNumber *const msg )

Slot table function for setting idle sleep time.

virtual bool Eaagles::BasicGL::GlutDisplay::event	(	const int	event,
		Basic::LcObject *const	obj = `0`
	)			`[virtual]`

Event function for the LcComponent interface.

Reimplemented from Eaagles::Basic::LcComponent.

bool Eaagles::BasicGL::GlutDisplay::isFullScreen ( ) [inline]

Returns true if full screen flag is true.

void Eaagles::BasicGL::GlutDisplay::reshapeIt	(	int	w,
		int	h
	)			`[virtual]`

Function for reshaping subdisplays.

Reimplemented from Eaagles::BasicGL::LcDisplay.

bool Eaagles::BasicGL::GlutDisplay::setResizeWindows ( const bool x ) [virtual]

Sets the flag okToResize.

bool Eaagles::BasicGL::GlutDisplay::setSlotResizeWindows ( const Basic::LcNumber *const msg ) [protected]

Calls the method setResizeWindows.

bool Eaagles::BasicGL::GlutDisplay::onEscKey ( ) [protected, virtual]

Exits with 0.

void Eaagles::BasicGL::GlutDisplay::specialEvent ( const int key ) [protected]

bool Eaagles::BasicGL::GlutDisplay::registerGlutDisplay	(	const int	id,
		GlutDisplay *const	display
	)			`[static, protected]`

Registers (add to list) this GlutDisplay & GLUT window ID.

bool Eaagles::BasicGL::GlutDisplay::unregisterGlutDisplay ( const int id ) [static, protected]

Unregisters (remove from list) this GLUT window ID.

GlutDisplay * Eaagles::BasicGL::GlutDisplay::findRegisteredGlutDisplay ( const int id ) [static, protected]

Finds the GlutDisplay for this GLUT window ID.

int Eaagles::BasicGL::GlutDisplay::findRegisteredWinId ( const GlutDisplay * dp ) [static, protected]

Finds the GLUT window ID for this GlutDisplay.

LcGraphic * Eaagles::BasicGL::GlutDisplay::pick ( const int item = -1 ) [protected]

Perform for select/pick operation; returns the selected (picked) graphic or zero(0) if nothing was selected. 1) When item == 0, returns nearest (by depth buffer) selected entry. 2) When item < 0, returns furthest (by depth buffer) selected entry. 3) When item > 0, returns the item'th selected entry or the first entry if there are less than 'item' entries 4) Returns zero(0) when there are no entries in the select buffer or if the LcGraphic for the select ID is not found..
