Class PickInfo

com.sas.graphics.components.PickInfo

public class PickInfo

A PickInfo provides a mapping from a data-element to all of its associated data and is contained inside each delivered ProbeEvent. A "Probe" event is delivered when a mouse pointer moves over a region of a Graph occupied by a data-element. A ProbeEvent object is passed as an argument to a ProbeListener's "probeUpdate" method. Register a ProbeListener to a Graph to receive these events.

"data-elements" are those chart graphics depicting the values found in the data model. For example the bars in the BarChart are data-elements but the axis, legend, titles, footnotes, etc are not.

Usage

"getX" and "getY" will return the X and Y screen coordinates of the mouse pointer where the event was generated.

Since:

SAS 9.1

Constructor Detail

PickInfo

public PickInfo(java.util.Vector[] newLabelValuePairs,
                int newObservationIndex,
                java.lang.Object newModel,
                int newX,
                int newY,
                java.awt.event.MouseEvent newMouseEvent)

Constructs a PickInfo object.

Parameters:

newLabelValuePairs - the data values associated with the data-element in the form of a series of vectors

newObservationIndex - the Row index in the model that is associated with the data-element

newModel - a handle to the data source

newX - the X portion of the screen coordinate that was picked against

newY - the Y portion of the screen coordinate that was picked against

newMouseEvent - the mouse event that triggered the ProbeEvent

Method Detail

getX

public int getX()

The X portion of the screen coordinate that was picked against.

Returns:

The X portion of the screen coordinate that was picked against

See Also:

setX(int), getY()

setX

public void setX(int newX)

Used to set the X portion of the screen coordinate that was picked against.

Parameters:

newX - the X portion of the screen coordinate that was picked against

See Also:

getX()

getY

public int getY()

The Y portion of the screen coordinate that was picked against.

Returns:

The Y portion of the screen coordinate that was picked against

See Also:

setY(int), getX()

setY

public void setY(int newY)

Used to set the Y portion of the screen coordinate that was picked against.

Parameters:

newY - the Y portion of the screen coordinate that was picked against

See Also:

getY()

getMouseEvent

public java.awt.event.MouseEvent getMouseEvent()

Get the mouse event that triggered the ProbeEvent.

Returns:

the mouse event that triggered the ProbeEvent.

See Also:

setMouseEvent(java.awt.event.MouseEvent)

setMouseEvent

public void setMouseEvent(java.awt.event.MouseEvent newMouseEvent)

Set the mouse event that triggered the ProbeEvent.

Parameters:

newMouseEvent - the mouse event that triggered the ProbeEvent.

See Also:

getMouseEvent()

getLabelValueCollection

public java.util.Vector[] getLabelValueCollection()

Return the data values associated with the data-element in the form of a series of vectors. Each vector entry is a separate Hashtable. The number of entries depicts the number of associated data-elements. For example if the BarChart has 5 response variables then 5 bars are generated for each valid data observation (considering summarized data). 5 Hashtables will be returned with the PickInfo. Each hashtable will contain a mapping from variable property to value.

setLabelValueCollection

public void setLabelValueCollection(java.util.Vector[] newLabelValuePairs)

Set the data values associated with the data-element in the form of a series of vectors. Each vector entry is a separate Hashtable. The number of entries depicts the number of associated data-elements. For example if the BarChart has 5 response variables then 5 bars are generated for each valid data observation (considering summarized data). 5 Hashtables will be returned with the PickInfo.

Parameters:

newLabelValuePairs - the array of hashtable associations

getObservationIndex

public int getObservationIndex()

Get the Row index in the model that is associated with the data-element

Returns:

the Row index in the model that is associated with the data-element

See Also:

setObservationIndex(int)

setObservationIndex

public void setObservationIndex(int newObservationIndex)

Set the Row index in the model that is associated with the data-element

Parameters:

newObservationIndex - the Row index in the model that is associated with the data-element

See Also:

getObservationIndex()

getModel

public java.lang.Object getModel()

Get a handle to the data source.

Returns:

a handle to the data source

See Also:

setModel(java.lang.Object)

setModel

public void setModel(java.lang.Object newModel)

Set a handle to the data source.

Parameters:

newModel - handle to the data source

See Also:

getModel()

equals

public boolean equals(java.lang.Object obj)

Determines whether another object is equal to this MarkerStyle.

The result is true if and only if the argument is not null and is a MarkerStyle object that has the same property values as this object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to test for equality with this MarkerStyle

Returns:

true if the objects are the same; false otherwise.
