Constructor & Destructor Documentation

TransferPoints::TransferPoints	(	QWidget *	widget,
		PointShape	shape
	)

Constructs a widget which is a child of widget, and the PointShape

Member Function Documentation

QRectF TransferPoints::boundingRect ( ) const

inline

Returns a QRectF with the given size or size of the widget

void TransferPoints::changePointColor ( QColor  c )

inlineslot

Stores the color in p_color if the color has changed

ConnectionType TransferPoints::connectionType ( ) const

inline

Returns the connectionType wich defines how the Points are connected

Warning:

{ the ConnectionType only changed the apperance of the Line }

bool TransferPoints::editable ( ) const

inline

Returns true if the item is editable

bool TransferPoints::eventFilter	(	QObject *	object,
		QEvent *	event
	)

Reimplementation of eventFilter to filter the different events and handel the MouseEvents to set/delet/move Points in the TransferfunktionWidget

void TransferPoints::firePointChange

(

)

Is called whenever the transferfunction has been modified, sort ans emit pointsChanged

void TransferPoints::paintPoints

(

)

Paints Transferpoints, connectionline, and Histogramm

const QVector< TPoint > & TransferPoints::points

(

)

const

Returns a QVector with the points of the transferfunction

void TransferPoints::pointsChanged ( int  )

signal

This signal is emitted when the points have changed

QSizeF TransferPoints::pointSize ( ) const

inline

Returns a QSizeF with the width and Height of the point

void TransferPoints::setBoundingRect ( const QRectF &  boundingRect )

inline

Sets m_bounds to a given Size

void TransferPoints::setConnectionPen ( const QPen &  pen )

inline

Defines the apperance of the Line, with a QPen

void TransferPoints::setConnectionType ( ConnectionType  connectionType )

inline

Sets the connectionType 

#ConnectionType

Warning:

{ the ConnectionType only changed the apperance of the Line }

void TransferPoints::setDisabled ( bool  disabled )

inlineslot

Disables widget input events if disable is true

void TransferPoints::setEditable ( bool  editable )

inline

Sets whether the item is editable.

void TransferPoints::setEnabled ( bool  enabled )

slot

Sets whether the item is enabled, an enabled widget handles keyboard and mouse events

void TransferPoints::setPointLock ( int  pos, LockType  lock  )

inline

Locks the "Point" to a Border #LockType

void TransferPoints::setPoints

(

const QVector< TPoint > &

points

)

Sets the points of the transferfunction

void TransferPoints::setPointSize ( const QSizeF &  size )

inline

Sets the size of a Point as QSizeF ( int width, int height )

void TransferPoints::setShapeBrush ( const QBrush &  brush )

inline

Defines the apperance of the Shape filling, with a QBrush

void TransferPoints::setShapePen ( const QPen &  pen )

inline

Defines the apperance of the ShapeLine, with a QPen

void TransferPoints::setSortType ( SortType  sortType )

inline

Sets the sortType 

#SortType

SortType TransferPoints::sortType ( ) const

inline

Returns the sortType which defines how the points are sortet

void TransferPoints::updateHistogram ( double *  histogram, int  size  )

slot

Updates the histogramm

void TransferPoints::updateMode ( int  mode )

slot

Modus of Transferfunction 0... 1D TF 1... 1D Gradient

void TransferPoints::updateValues ( glm::vec2 *  values, int  size  )

slot

Update values
