Member Function Documentation

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

Draw CanvasObject on 'g', using internal CCS values.

Reimplemented from CanvasObject.

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

Return an identical copy of this CanvasObject.

Reimplemented from CanvasObject.

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

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

void CanvasArrow::setPosition (  double    x,
double    y
)  [inline]

Parameters are assumed Image Coordinate System values.

Reimplemented from ScribbleObject.

void CanvasArrow::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 CanvasArrow::setZoomFactor (  double    zoomFactor )  [inline]
 

Scale CanvasObject according to 'zoomFactor'.

The internal ICS values are taken as base values to calculate the associated CCS values.

Reimplemented from CanvasObject.

double CanvasArrow::getLength (    )  [inline]
 

void CanvasArrow::setLength (  double    length )  [inline]
 

int CanvasArrow::getAngle (    )  [inline]

Vector CanvasArrow::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.
