Constructor Detail

IlvAnchoredLabel

public IlvAnchoredLabel(IlvGraphic reference,
                        IlvMapLabel label)

Constructs an IlvAnchoredLabel by specifying a reference IlvGraphic and an IlvMapLabel. The reference is not allowed to be null.

IlvAnchoredLabel

public IlvAnchoredLabel(IlvInputStream stream)
                 throws IlvReadFileException

Reads an IlvAnchoredLabel from an IlvInputStream.

Throws:

IlvReadFileException

IlvAnchoredLabel

public IlvAnchoredLabel(IlvAnchoredLabel source)

Constructs an IlvAnchoredLabel by copying an existing one.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this IlvAnchoredLabel into an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvDoubleGraphicHandleBag

Parameters:

stream - the output stream.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

object1Name

protected String object1Name()

Returns the name of the first object in the IVL file.

Overrides:

object1Name in class IlvDoubleGraphicHandleBag

object2Name

protected String object2Name()

Returns the name of the second object in the IVL file.

Overrides:

object2Name in class IlvDoubleGraphicHandleBag

GetAnchoredLabel

public static IlvAnchoredLabel GetAnchoredLabel(IlvMapLabel label)

Retrieves the IlvAnchoredLabel from an IlvMapLabel.

getReferencePoint

public IlvPoint getReferencePoint()

Retrieves the reference point. If no reference point has been set, a reference point is computed as the center of the reference object bounding box.

setReferencePoint

public void setReferencePoint(IlvPoint reference)

Sets the reference point.

getReference

public IlvGraphic getReference()

Retrieves the reference IlvGraphic.

setReference

public void setReference(IlvGraphic g)

Sets the reference IlvGraphic.

Since:

JViews 5.5

getLabel

public IlvMapLabel getLabel()

Retrieves the IlvMapLabel.

draw

public void draw(Graphics g,
                 IlvTransformer t)

Draws the IlvAnchoredLabel at transformer t.

Overrides:

draw in class IlvDoubleGraphicHandleBag

Parameters:

g - the destination Graphics.

t - the transformation used to draw the object.

See Also:

IlvGraphic.callDraw(Graphics,IlvTransformer), IlvGraphic.boundingBox(IlvTransformer), IlvGraphic.zoomable(), IlvGraphic

contains

public boolean contains(IlvPoint p,
                        IlvPoint tp,
                        IlvTransformer t)

Overrides the default method to only return true when the point is in the label, the reference, or the line.

Overrides:

contains in class IlvDoubleGraphicHandleBag

Parameters:

p - The point.

tp - The transformed point.

t - The transformer.

Returns:

When the point is in the label, the reference, or the line, true is returned.

Since:

JViews 8.1

See Also:

IlvGraphic.contains(ilog.views.IlvPoint, ilog.views.IlvPoint, ilog.views.IlvTransformer)

zoomable

public boolean zoomable()

Returns always false. This object is not zoomable because it contains a fixed size point.

Overrides:

zoomable in class IlvDoubleGraphicHandleBag

See Also:

IlvGraphic, IlvGraphic.draw(java.awt.Graphics, ilog.views.IlvTransformer), IlvGraphic.boundingBox(IlvTransformer), IlvManager

copy

public IlvGraphic copy()

Returns a copy of the IlvAnchoredLabel.

Overrides:

copy in class IlvDoubleGraphicHandleBag

Returns:

A copy of the object.

See Also:

IlvGraphic

moveLabel

public void moveLabel(IlvPoint p)

Moves the IlvMapLabel contained in this IlvAnchoredLabel. Since this operation can change the bounding box of the object, this method calls the graphic bag applyToObject method on the IlvMapLabel.

setLabelOffset

public void setLabelOffset(double dx,
                           double dy)

Sets the label offset of this IlvAnchoredLabel if the label exists.

drawLine

protected void drawLine(Graphics g,
                        IlvTransformer t)

Draws the line between the reference point and the IlvMapLabel. If the point is inside the label, no line is drawn.

makeSelection

public IlvSelection makeSelection()

Creates a selection object for this graphic object. Because this object cannot be resized using the interactor, the implementation of this method creates an instance of the class IlvUnresizeableDrawSelection.

Overrides:

makeSelection in class IlvGraphic

See Also:

IlvDrawSelection

setLineColor

public void setLineColor(Color color)

Sets the color used to draw the line. This property supports IlvBlinkingColor.

getLineColor

public Color getLineColor()

Retrieves the color used to draw the line.

setLineVisible

public void setLineVisible(boolean visible)

Tells the IlvAnchoredLabel if it should display the line.

isLineVisible

public boolean isLineVisible()

Tells if the IlvAnchoredLabel is displaying the line.
