Member Function Documentation

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

Implements CanvasObject abstract function. This side of the tree is not clonable, nor need it be? Reimplemented from CanvasObject.

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

Implements CanvasObject "interface". Reimplemented from CanvasObject. Reimplemented in CanvasHxBlob2d, and CanvasCorbaBlob2d.

boolean CanvasFigure::isHitCcs (  int    x, int    y, Graphics2D    g )  [inline]

A more specialized version of isHitCcs that uses the Graphics2d.hit and the getShape() member function to determine if this figures is selected with the given position. Uses hitOnStroke to choose between hit on stroke or hit on interior. Reimplemented from CanvasObject.

boolean CanvasFigure::hasNoColor (    )  [inline]

Color CanvasFigure::getColor (    )  [inline]

void CanvasFigure::setColor (  Color    color )  [inline]

Reimplemented in CanvasHxBlob2d, and CanvasCorbaBlob2d.

boolean CanvasFigure::getFilled (    )  [inline]

void CanvasFigure::setFilled (  boolean    filled )  [inline]

boolean CanvasFigure::getDashed (    )  [inline]

void CanvasFigure::setDashed (  boolean    dashed )  [inline]

boolean CanvasFigure::hasLineWidth (    )  [inline]

float CanvasFigure::getLineWidth (    )  [inline]

void CanvasFigure::setLineWidth (  float    linew )  [inline]

float CanvasFigure::getTransparency (    )  [inline]

void CanvasFigure::setTransparency (  float    trans )  [inline]

Reimplemented in CanvasHxBlob2d, and CanvasCorbaBlob2d.

Vector CanvasFigure::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 CanvasObject. Reimplemented in CanvasHxBlob2d, CanvasHxBSplineCurve, CanvasHxSampledBSplineCurve, CanvasCorbaBlob2d, CanvasCorbaBSplineCurve, and CanvasCorbaSampledBSplineCurve.

abstract Shape CanvasFigure::getShape (    )  [protected, pure virtual]

Derived classes have to implement this method to supply the shape that represents the CanvasFigures. It is used to draw to figure as well as determine which figure is selected (hit) by the cursor within a canvas. Reimplemented in CanvasHxBlob2d, CanvasHxBSplineCurve, CanvasHxHistogram, CanvasHxPolyline2d, CanvasHxSampledBSplineCurve, CanvasCorbaBlob2d, CanvasCorbaBSplineCurve, CanvasCorbaHistogram, CanvasCorbaPolyline2d, and CanvasCorbaSampledBSplineCurve.

abstract boolean CanvasFigure::hitOnStroke (    )  [protected, pure virtual]

Derived classes have to implement this method to indicate whether they are selected (hit) based on their stroke (border) or on their interior. Reimplemented in CanvasHxBlob2d, CanvasHxBSplineCurve, CanvasHxHistogram, CanvasHxPolyline2d, CanvasHxSampledBSplineCurve, CanvasCorbaBlob2d, CanvasCorbaBSplineCurve, CanvasCorbaHistogram, CanvasCorbaPolyline2d, and CanvasCorbaSampledBSplineCurve.

void CanvasFigure::setupDrawMode (  Graphics    g )  [inline, protected]

Setup drawmode for 'g'. Reimplemented from CanvasObject.
