Constructor & Destructor Documentation

TfpList::TfpList	(	TfPoint *	_head,
		TfPoint *	_tail
	)

Constructs a ne TfpList object

Parameters:

	_head	The head of the list
	_tail	The tail of the list

Member Function Documentation

void TfpList::addPoint	(	const float	x,
		const float	y,
		const float	r,
		const float	g,
		const float	b,
		const float	a
	)

Adding a point to the list if it is possible. If there is already a point at the desired place, the point would not be added.

Parameters:

	x	X-coordinate of the point
	y	Y-coordinate of the point
	r	R-Value of the color of the point
	g	G-Value of the color of the point
	b	B-Value of the color of the point
	a	A-Value of the color of the point

void TfpList::changeColorOfPoint	(	const float	x,
		const float	y,
		const float	r,
		const float	g,
		const float	b
	)

Change the color of the point that was selected

Parameters:

	x	X-coordinate of the point
	y	Y-coordinate of the point
	r	R-Value of the color of the point
	g	G-Value of the color of the point
	b	B-Value of the color of the point

void TfpList::clean

(

)

Delete all elements of the transfer point list

void TfpList::constructList

(

std::list< TfPoint * >

liste

)

Construct a new transfer point list out of a std::list of tfpoints

Parameters:

list

List containing pointers to tfpoints

void TfpList::dragPoint	(	const float	x,
		const float	y
	)

Drag the point corresponding to the coordinate

Parameters:

	x	X-coordinate of the point
	y	Y-coordinate of the point

TfPoint * TfpList::getHead

(

)

Return the head of the list

Returns:

Head of the point list

bool TfpList::isPointClicked	(	const float	x,
		const float	y
	)

Return a boolean value indicating whether the click was on a transfer point x X-coordinate of the point y Y-coordinate of the point

Returns:

boolean Vlue indicating whether the click was on a tranfer point or not

void TfpList::removePoint	(	const float	x,
		const float	y
	)

Remove the point of the list if that is possible, because if ther is no point at the choosen place, no point can be removed

Parameters:

	x	X-coordinate of the point
	y	Y-coordinate of the point

void TfpList::setPositionOfDraggedPoint	(	const float	x,
		const float	y,
		const float	a
	)

Set the position and alpha-value of the dragged point

Parameters:

	x	X-coordinate of the point
	y	Y-coordinate of the point
	a	Alpha-Value of the point
