public class TLcdICAONavaidLabelPainter
extends TLcdGXYStampLabelPainter

This class contains all the logic needed to paint navaid labels. For each type of navaid, a specific label painter exists which extends this class.

This class has a few options (additional to the options of the TLcdGXYLabelPainter class which it extends):

• a navaid label may or may not contain the coordinates of the object it belongs to (use the setPaintCoordinates(boolean) method}).
• the paintCombined option allows the user to paint all labels no matter what the type of the corresponding navaid is or, to paint only one label for each navaid (navaids of type VOR-DME, VORTAC or NDB-DME consist of two objects, so they'd normally have two labels).
• You can set the expressions that are used with the setXXXExpression methods. This makes it possible to use this label painter with custom ILcdNavaid objects. For instance if the 'name' property in your custom navaid is called 'myName', you can call setNameExpression( myNavaidType.getProperty( "myName" ).getName()) .

This label painter evaluates its expressions using an instance of TLcdDataObjectExpressionLanguage.

aWidth - the width of the label.

aHeight - the height of the label.

aAnchorPoint - The anchor point, retrieved using #anchorPointSFCT.

aMode - the mode to consider.

aGXYContext - the context.

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 - The Graphics instance on which the pin will be painted.

aMode - The mode in which the pin will be painted. See 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 axis

aPinPointSFCT - The point in AWT coordinates where the pin attaches to the label

Returns:

Whether or not the pin needs to be drawn.

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.

setWithPin

public void setWithPin(boolean aWithPin)

The property withPin determines whether a pin should be drawn from the object to the label. The pin is attached to the object at the anchor point and to the label stamp at the pin point.

Parameters:

aWithPin - true to paint a pin connecting the label and the object.

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 is true 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.
