Constructor Detail

PickEvent

public PickEvent(Component source,
                 int id,
                 long when,
                 int modifiers,
                 int x,
                 int y,
                 int clickCount,
                 boolean popupTrigger)
Construct a PickEvent object at point (x,y).

Parameters:
source - the Component that originated the event
id - an int that identifies the event
when - a long that gives the time the event occurred
modifiers - an int that gives the modifier keys down during event (e.g. shift, ctrl, alt, meta)
x - an int, the x coordinate of the point (x,y)
y - an int, the y coordinate of the point (x,y)
clickCount - an int which specifies the number of mouse button clicks necessary to trigger the event
popupTrigger - is a boolean, true if this event is a trigger for a popup menu

PickEvent

public PickEvent(MouseEvent event)
Construct a PickEvent object.

Parameters:
event - a MouseEvent
Method Detail

getNode

public ChartNode getNode()
Gets this ChartNode.


pointToLine

public static double pointToLine(int Px,
                                 int Py,
                                 int[] devA,
                                 int[] devB)
Compute the distance from the point (Px,Py) to the line segment AB. If the closest point from P to the line AB is not between A and B then the distance to the closer of A and B is returned.

Parameters:
Px - an int, the x coordinate of the point (Px,Py)
Py - an int, the y coordinate of the point (Px,Py)
devA - an int array which contains the point which defines the head of the line segment.
devB - an int array which contains the point which defines the tail of the line segment.
Returns:
a double, the distance from the point (Px,Py) to the line segment AB.

setNode

public void setNode(ChartNode node)
Sets the ChartNode.

Parameters:
node - the ChartNode to be set
