Point aPointSFCT)
Returns the anchor point of this icon.
|

getHeight(double[] aParameters)
Returns the height of the icon for the given parameter values.
|

paintIcon(Graphics aGraphics,
int aX,
int aY,
double[] aParameters)
Paint the icon at the specified location for the parameters

void paintIcon(Graphics aGraphics, int aX, int aY, double[] aParameters)
aGraphics
- the Graphics on which the icon is paintedaX
- the x coordinate at which the icon is painted. aX
is the
x-coordinate of the top left corner point of the icon.aY
- the y coordinate at which the icon is painted. aY
is the
y-coordinate of the top left corner point of the icon.aParameters
- the parameter valuesint getWidth(double[] aParameters)
aParameters
- the parameter values as passed in paintIcon(java.awt.Graphics, int, int, double[])
int getHeight(double[] aParameters)
aParameters
- the parameter values as passed in paintIcon(java.awt.Graphics, int, int, double[])
void anchorPointSFCT(double[] aParameters, Point aPointSFCT)
Returns the anchor point of this icon. The anchor point of an icon is the point on the icon that is attached to the underlying object. For example: a circle icon is attached to an underlying point object by its center. An arrow icon can for example be attached to its object at the start of the arrow. The x-coordinate of the anchor point typically lies between 0 and getWidth(). The y-coordinate typically lies between 0 and getHeight().
Note that implementations don't need to take the anchor point into account when implementing the
paintIcon
method. The coordinates passed to that method always represent the top
left corner of the icon. Callers of the paint
method should make sure that the anchor point is
taken into account.
A good default implementation can be to use the middle of the icon:
aPointSFCT.setLocation(getWidth(aParameters) / 2, getHeight(aParameters) / 2);
aParameters
- the parameter valuesaPointSFCT
- the point that has to be moved to the location of the anchor point
of this icon.
