Member Function Documentation

void CanvasPolyline::draw (  Graphics    g )  [inline, virtual]

Draw CanvasObject on 'g', using internal CCS values. Reimplemented from CanvasObject. Reimplemented in CanvasColoredPolyline.

Object CanvasPolyline::clone (    )  [inline, virtual]

Return an identical copy of this CanvasObject. Reimplemented from CanvasObject. Reimplemented in CanvasColoredPolyline.

boolean CanvasPolyline::isInside (  double    x, double    y )  [inline]

boolean CanvasPolyline::isNear (  double    x, double    y )  [inline]

void CanvasPolyline::setDimension (  double    w, double    h )  [inline]

Resize CanvasObject to width 'w' and height 'h'. Parameters are assumed Image Coordinate System values. Reimplemented from ScribbleObject.

void CanvasPolyline::doPixelFit (  double    zoomFactor )  [inline]

Round internal ICS values to nearest natural number. Although the ICS values are changed, they are not converted to 'integer' internally. Reimplemented from ScribbleObject.

void CanvasPolyline::doMove (  double    w, double    h )  [inline]

Move CanvasObject 'w' positions in x-direction, and 'h' posi- tions in y-direction. Parameters are assumed Image Coordinate System values. Reimplemented from ScribbleObject.

void CanvasPolyline::addPoint (  double    x, double    y )  [inline]

Reimplemented from ScribbleFigure.

boolean CanvasPolyline::removePoint (  int    index )  [inline]

Reimplemented from ScribbleFigure. Reimplemented in CanvasColoredPolyline.

boolean CanvasPolyline::removeLastPoint (    )  [inline]

Reimplemented from ScribbleFigure.

boolean CanvasPolyline::isClosed (    )  [inline]

void CanvasPolyline::setClosed (  boolean    b )  [inline]

double [] CanvasPolyline::getXPoints (    )  [inline]

double [] CanvasPolyline::getYPoints (    )  [inline]

int CanvasPolyline::getNrPoints (    )  [inline]

void CanvasPolyline::pointsToMediator (    )  [inline]

void CanvasPolyline::makeBSpline (  int    degree )  [inline]

Vector CanvasPolyline::getVisualChangeMethods (    )  [inline]

Builds up a list of functions that are to fill a menu for changing the visualization aspects of an object. Classes derived from this one typically add their class-specific methods to their parents' methods by first calling the parent to fill the vector and then add their own. The result is a Vector of CallableMethods. Reimplemented from ScribbleFigure.

boolean CanvasPolyline::isInsideCcs (  int    x, int    y )  [inline]

To be removed. Reimplemented from CanvasObject.

boolean CanvasPolyline::isNearCcs (  int    x, int    y )  [inline]

To be removed. Reimplemented from CanvasObject.

void CanvasPolyline::setDimension (  int    w, int    h )  [inline]

Reimplemented from ScribbleObject.

void CanvasPolyline::doMove (  int    w, int    h )  [inline]

Reimplemented from ScribbleObject.

int CanvasPolyline::changePoint (  int    index, int    x, int    y )  [inline]

Reimplemented from ScribbleFigure.

void CanvasPolyline::addPoint (  int    x, int    y )  [inline]

Reimplemented from ScribbleFigure.

void CanvasPolyline::removeRedundantPoints (    )  [inline]

int [] CanvasPolyline::getCcsXPoints (    )  [inline]

int [] CanvasPolyline::getCcsYPoints (    )  [inline]

void CanvasPolyline::initPoly (  double    xpoints[], double    ypoints[], int    npoints, boolean    closed )  [inline, protected]

void CanvasPolyline::transformICStoCCS (    )  [inline, protected]

Perform a full ICS to CCS coordinate transformation. Reimplemented from CanvasObject. Reimplemented in CanvasColoredPolyline.

void CanvasPolyline::transformCCStoICS (    )  [inline, protected]

Perform a full CCS to ICS coordinate transformation. This function is used only for scribbled objects. Reimplemented from CanvasObject. Reimplemented in CanvasColoredPolyline.

void CanvasPolyline::setBox (    )  [inline, protected]
