in interfaceILcdGXYLabelPainter2
- Overrides:
setObject
in classTLcdGXYPolylineLabelPainter
- Parameters:
aObject
- the object to paint a label for.- See Also:
-
getDeclinationFormat
Returns the format for the magnetic declination value.- Returns:
- the format for the declination value, or null if the value is displayed as is.
-
setDeclinationFormat
Sets the format for the magnetic declination value.
The format needs to accept

-
retrieveLabels
Description copied from class:TLcdGXYPolylineLabelPainter
Returns an array containing the lines of text for a single label.
This method is called to retrieve the actual label text. Each array element is treated as a line of the label defined by
setObject
,setLabelIndex
andsetSubLabelIndex
. If this method returns null or a zero-length array, no label will be painted.A text line can contain HTML commands if its content is surrounded by an
<html>
tag.By default, this method calls
TLcdGXYPolylineLabelPainter.retrieveLabels(com.luciad.view.gxy.ILcdGXYContext)
, which returns a single line of text (i.e. an array of oneString
) containinggetObject().toString()
, or null if the object has an empty toString() result. Override this method to return other text. Never modify the content of the returned array.This method is only called for the label painter's supported label and sublabel indices. Override the
getLabelCount
and/orgetSubLabelCount
methods if you want to define multiple labels per domain object.- Overrides:
retrieveLabels
in classTLcdGXYPolylineLabelPainter
- Parameters:
aMode
- the label painting modeaGXYContext
- the context in which the labels should be painted- Returns:
- the set of String objects to be used as label for this object, depending on the mode.
-
retrievePointList
Retrieves the point list making up the polygon for the valued polygon set on this label painter.- Overrides:
retrievePointList
in classTLcdGXYPolylineLabelPainter
- Returns:
- the point list making up the valued polygon.
- See Also:

without a layout set on it.Override this method if your
ILcdGXYView
implementation is not ajava.awt.Container
or if you add components to another container than the specifiedILcdGXYView
.- Parameters:
aGXYView
- TheILcdGXYView
for which to check if a component can be added.- Returns:
true
if a component can be added,false
otherwise.- See Also:
-
addComponentToGXYView
Adds the specified interactive label to the user interface. By default this method casts the given
ILcdGXYView
tojava.awt.Container
and adds the component to the view.Override this method if your implementation of
ILcdGXYView
does not extend fromjava.awt.Container
or if you want to add the interactive label to anotherjava.awt.Container
because, for instance, you already need to add other components to the specifiedILcdGXYView
.If you override this method, you also need to override
canAddComponentToGXYView
andremoveComponentFromGXYView
as these methods are closely related to each other.This method will not be called if
canAddComponentToGXYView
returnsfalse

-
setHaloPinColor
Sets the color of the halo to be added around pins.- Parameters:
aColor
- the new halo color- See Also:
-
isUseImageCache
public boolean isUseImageCache()Returnstrue
when image caching for labels with a halo is enabled,false
otherwise.- Returns:
true
when label image caching is enabled,false
otherwise- See Also:
-
setUseImageCache
public void setUseImageCache(boolean aUseCache) Sets whether or not labels with halos should be cached as images. Creating a halo for a label is an expensive operation, so enabling image caching can considerably improve performance.- Parameters:
aUseCache
- specifies whether image caching should be enabled- See Also:
-
clearImageCache
public void clearImageCache()Clears the entire label image cache. To remove a single label from the cache, useclearImageCache(Object)
.- See Also:
-
clearImageCache
Clears the label image cache for the given object. The next time this object is painted, a new image will be created and cached for it. To remove all cached images in one go, useclearImageCache()
.- Parameters:
aObject
- the object for which the cache to be cleared.- See Also:
-
pinPointSFCT
protected boolean pinPointSFCT(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext, Point aAnchorPoint, Rectangle aLabelBounds, double aRotation, Point aPinPointSFCT) Determines where the pin attaches to the label. This implementation attaches the pin on the label bounds, with the pin going towards the center of the label bounds.- Parameters:
aGraphics
- TheGraphics
instance on which the pin will be painted.aMode
- The mode in which the pin will be painted. SeeILcdGXYLabelPainter2.paintLabel(java.awt.Graphics, int, ILcdGXYContext)
for more information.aGXYContext
- The instance containing the context in which the pin will be painted.aAnchorPoint
- The point in AWT coordinates where the pin attaches to the object representation (see #anchorPointSFCT)aLabelBounds
- The bounds of the label in AWT coordinates.aRotation
- The rotation of the label in radians, positive going from the x to the y axisaPinPointSFCT
- The point in AWT coordinates where the pin attaches to the label- Returns:
- Whether or not the pin needs to be drawn.
- See Also:
-
paintPin
protected void paintPin(Graphics aGraphics, int aMode, int aStartPointX, int aStartPointY, int aEndPointX, int aEndPointY) Draws a label pin on the given graphics between the given lines. Overwrite this method if you want to change the look of the pin, for example by manipulating the graphics passed.- Parameters:
aGraphics
- the graphics to paint the pin on.aMode
- the mode this objects label is painted in (e.g. ILcdGXYLabelPainter.SELECTED).aStartPointX
- the x coordinate of the start point of the pin.aStartPointY
- the y coordinate of the start point of the pin.aEndPointX
- the x coordinate of the end point of the pin.aEndPointY
- the y coordinate of the end point of the pin.- See Also:
-
setWithPin
public void setWithPin(boolean aWithPin) The propertywithPin
determines whether a pin should be drawn from the object to the label. The pin is attached to the object at theanchor point
and to the label stamp at thepin point
.- Parameters:
aWithPin
- true to paint a pin connecting the label and the object.- See Also:
-
isWithPin
public boolean isWithPin()Returns whether a pin is drawn from the object to the label.- Returns:
true
if a pin is drawn from the object to the label- See Also:
-
setWithAnchorPoint
public void setWithAnchorPoint(boolean aWithAnchorPoint) Determines whether to draw an anchor point atanchorPointSFCT
.- Parameters:
aWithAnchorPoint
- true to paint an anchor point- See Also:
-
isWithAnchorPoint
public boolean isWithAnchorPoint()Returns whether to draw an anchor point atanchorPointSFCT
.- Returns:
true
if an anchor point is painted,false
otherwise- See Also:
-
setClassTraceOn
public static void setClassTraceOn(boolean aClassTraceOn) Deprecated.This method has been deprecated. It is recommended to use the standard Java logging framework directly.Enables tracing for all instances of this class. If the argument istrue
then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.- Parameters:
aClassTraceOn
- if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.
