public class TLcdGXYAISPointListPainter extends TLcdGXYPointListPainter
TLcdGXYPointListPainter, but paints an
icon if the point list contains only a single point.
By default, the points are painted by a TLcdGXYAISIconProviderPainter.
The symbology usage can be changed in two ways:
setPointPainter method can be used to define another painter,getPointPainter method can be used to retrieve the default
painter. The TLcdGXYAISIconProviderPainter class provides a setSymbolProvider
method to change its symbol provider.
Like its super class, this painter accepts instances of any implementation
of the ILcdPointList interface.

TLcdGXYAISPointListPainter object.
By default, pointLists will be drawn as polygons, unless they contain only one point.
In the latter case, an instance of the TLcdGXYAISIconProviderPainter class will be
used to draw an icon at the location of the single point.
public Object clone()
ILcdCloneableMakes Object.clone() public.
java.lang.Object, it can be implemented like this:
public Object clone() {
try {
return super.clone();
} catch ( CloneNotSupportedException e ) {
// Cannot happen: extends from Object and implements Cloneable (see also Object.clone)
throw new RuntimeException( e );
}
}
clone in interface ILcdCloneableclone in interface ILcdGXYEditorProviderclone in interface ILcdGXYPainterProviderclone in class TLcdGXYPointListPainterObject.clone()public void setObject(Object aObject)
The specified object should be an instance of an implementation
of the ILcdPointList interface.

TLcdGXYPointListPainter
This implementation will use the specified render mode to determine how the object needs to be
rendered. In ILcdGXYPainter.TRANSLATING mode, the ILcdPointList object is rendered as if
all points were moved along the same distance in view coordinates as passed in the context. In
ILcdGXYPainter.RESHAPING mode, the object is painted with one point moved as defined in the context.
In ILcdGXYPainter.CREATING mode, the object is painted as if the current mouse position is the last
point of the ILcdPointList. In the above render modes, the object is painted using
the edit paint mode (ALcdGXYAreaPainter.getEditMode()).
In the render mode ILcdGXYPainter.SELECTED, the object is painted using the selection paint mode
(ALcdGXYAreaPainter.getSelectionMode()). In all other render modes, the paint mode (TLcdGXYPointListPainter.getMode())
is used.
Note: when the paint mode is set to TLcdGXYPointListPainter.POINT or TLcdGXYPointListPainter.POLYLINE, the objects will
be painted as, respectively points and polylines. The selectionMode and editMode property are not
taken into account when finding the mode in which the object should be painted.

TLcdGXYPointListPainter
This implementation will use the specified paint mode to determine how
the object is represented. Depending on the representation of the ILcdPointList object,
the object is touched when
TLcdGXYPointListPainter.FILLED,
ILcdGXYPainter.SELECTED.
The method insidePolygon determines whether the current mouse position
is located inside the ILcdPointList object or not.
It is not possible to derive from this method which part of the point list has been touched.
To determine which part of the ILcdPointList object is touched, the methods getTouchedPoint and getTouchedSegment will return
the required information.

TLcdGXYPointListPainterIf this method returns without exception the bounds argument must encompass the representation of the object. A point outside the bounds will not be contained within the painted object.
The bounds returned in this method can be seen as the equivalent in the view space of the bounds in the model
space for ILcdBounded objects.
