public class TLcdGXYCompositeLabelPainter
extends ALcdGXYLabelPainter
implements ILcdGXYLabelPainterProvider, ILcdGXYLabelEditor, ILcdGXYLabelEditorProvider

This label painter composes a list of ILcdGXYLabelPainters into 1 label painter. It does so by remapping the label and sublabel indices of the delegate label painters to get consistent indices.

An advantage of using this class is that labels of the same object can be easily represented in different ways. For example one of the labels of an object can be represented by an icon (e.g. by using TLcdGXYLabelPainterAdapter) while another label can be represented textually (e.g by using TLcdGXYLabelPainter).

This label painter can also be used as ILcdLabelGXYEditor. It is not necessary to add a label editor for each label painter. In case no label editor is added for a label painter, no editing will be performed for those labels.

The remapping of the indices can be done in two ways.

1) SHIFT_LABEL_INDEX

When using this mode the label indices are shifted. For example label painter P1 has 2 labels, each with 2 sublabels, label painter P2 has 3 labels, each with one sublabel. Then the composite label painter has the following labels and sublabels :

label	sublabel	target label painter	target label	target sublabel
0	0	P1	0	0
0	1	P1	0	1
1	0	P1	1	0
1	1	P1	1	1
2	0	P2	0	0
3	0	P2	1	0
4	0	P2	2	0

2) SHIFT_SUBLABEL_INDEX

When using this mode the sublabel indices are shifted. For example label painter P1 has 2 labels, each with 2 sublabels, label painter P2 has 3 labels, each with one sublabel. Then the composite label painter has the following labels and sublabels :

label	sublabel	target label painter	target label	target sublabel
0	0	P1	0	0
0	1	P1	0	1
0	2	P2	0	0
1	0	P1	1	0
1	1	P1	1	1
1	2	P2	1	0
2	0	P2	2	0

Note :

This painter passes ( null, null ) to the delegate label painter's getLabelCount method. The delegate label painter should take this into account.

Before calling this method, the domain object, the label index, the sublabel index and the location of the label should be set using the respective methods.

Specified by:

isLabelTouched in interface ILcdGXYLabelPainter2

Parameters:

aGraphics - The Graphics instance on which the label is painted.

aMode - the mode to consider. This is a bitwise combinations of several constants. See ILcdGXYLabelPainter2.paintLabel(java.awt.Graphics, int, com.luciad.view.gxy.ILcdGXYContext) for more information.

labelAnchorPointSFCT

public void labelAnchorPointSFCT(Graphics aGraphics,
                                 int aMode,
                                 ILcdGXYContext aGXYContext,

                          throws TLcdNoBoundsException

Description copied from interface: ILcdGXYLabelPainter2

Sets aPointSFCT to the anchor point of the label specified by setObject, setLabelIndex and setSubLabelIndex.

If the location index is less than 0, the label anchor point is unambiguously determined by the label location. The actual label is to be painted somewhere around this anchor point. This method is typically called to compare the result with the label bounds, thus determining the exact relation between the label and its location.

Before calling this method, the domain object, the label index, the sublabel index and the location of the label should be set using the respective methods.

Specified by:

labelAnchorPointSFCT in interface ILcdGXYLabelPainter2

Parameters:

aGraphics - The Graphics instance on which the label is painted.

aMode - The mode to consider. This can be a bitwise combination of several constants. See ILcdGXYLabelPainter2.paintLabel(java.awt.Graphics, int, com.luciad.view.gxy.ILcdGXYContext) for more information.

aGXYContext - The ILcdGXYContext that can be used to retrieve extra information.

aPointSFCT - The point which will be updated to reflect the location of the anchor point.

Throws:

TLcdNoBoundsException - if the Object doesn't have any valid anchor point, e.g. if it is always invisible in the current projection.

labelBoundsSFCT

public double labelBoundsSFCT(Graphics aGraphics,
                              int aMode,
                              ILcdGXYContext aGXYContext,
                              Rectangle aRectangleSFCT)
                       throws TLcdNoBoundsException

Description copied from interface: ILcdGXYLabelPainter2

Calculates the bounds of the label that can be painted. The bounds are set as a side effect in aRectangleSFCT, the orientation of aRectangleSFCT is returned as an angle.

The bounds represent the upper left point of the label, and a width and a height. The rotation value represents the rotation of the label bounds around the upper left point.

The domain object, the label index, the sublabel index and the location of the label for which the bounds are retrieved should be set before calling this method using the respective methods.

Note that if this label painter is used in conjunction with a labeling algorithm, the bounds should preferably be independent of the location, as this will yield the best results.

Specified by:

labelBoundsSFCT in interface ILcdGXYLabelPainter

Specified by:

labelBoundsSFCT in interface ILcdGXYLabelPainter2

Parameters:

aGraphics - the aGraphics to consider.

aMode - the representation mode of the label.

aGXYContext - the ILcdGXYContext the drawing depends on.

aRectangleSFCT - the Rectangle containing the bounds of the label in view / graphics coordinates as side effect.

Returns:

the angle orientation of the rectangle around the labels in RADIANs, clockwise, 0 at 3 o'clock.

Throws:

TLcdNoBoundsException - if the Object doesn't have any valid bounds, e.g. if it is always invisible in the current projection.

Parameters:

aObject - the object to find a label painter for

Returns:

a label painter that can be used to label the object; or null if no label painter could be found for the given object, or the object could not be set on the retrieved label painter.
