Constructor Detail

LabelTextPainter

public LabelTextPainter(java.lang.String s)

Creates default label text painter for specified text string.

Parameters:

s - text string.

LabelTextPainter

public LabelTextPainter()

Creates default label text painter for specified text string.

Method Detail

setText

public void setText(java.lang.String s)

Sets text for text painter.

Specified by:

setText in interface AbstractTextPainter

Overrides:

setText in class TextPainter

Parameters:

s - text string.

setRotationAngle

public void setRotationAngle(double angle)

Sets rotation angle in radians for text.

Specified by:

setRotationAngle in class RotatedLabelPainter

Parameters:

angle - rotation angle

setRotationPoint

public void setRotationPoint(Point2D rotPoint)

Sets rotation point.

Specified by:

setRotationPoint in class RotatedLabelPainter

Parameters:

rotPoint - rotation point

setRelativePosition

public void setRelativePosition(float pos)

Sets relative (to rotation point) position for not rotated labels. Should be in range [-1;1].

Specified by:

setRelativePosition in class RotatedLabelPainter

Parameters:

pos - relative position

getRelativePosition

public float getRelativePosition()

Description copied from class: RotatedLabelPainter

Returns relative position for the label

Specified by:

getRelativePosition in class RotatedLabelPainter

Returns:

relative position for the label

getRotationPoint

public Point2D getRotationPoint()

Returns rotation point.

Specified by:

getRotationPoint in class RotatedLabelPainter

Returns:

rotPoint rotation point

getRotationAngle

public double getRotationAngle()

Returns rotation angle in radians for text.

Specified by:

getRotationAngle in class RotatedLabelPainter

Returns:

angle rotation angle

getFullSize

protected java.awt.Dimension getFullSize(java.awt.FontMetrics fm)

Returns full not rotated text size.

Specified by:

getFullSize in class RotatedLabelPainter

Parameters:

fm - text font metrics.

Returns:

fullSize text full size.

findBounds

public Rectangle2D findBounds(AbstractGraphics g,
                              Rectangle2D r)

This method finds bounds for the label. Used for title painting boundary determination and centering.

Specified by:

findBounds in interface AbstractTextPainter

Overrides:

findBounds in class TextPainter

Parameters:

g - abstract graphics

r - rectangle boundaries

Returns:

bounding box

getPreferredBounds

public Rectangle2D getPreferredBounds(java.awt.FontMetrics fm)

Preferred bounds are enough to paint full label. Matters only if rotation point is set. Otherwise use the getFullSize method to get size of label.

Specified by:

getPreferredBounds in class RotatedLabelPainter

Parameters:

fm - FontMetrics

font - font of label

Returns:

preferred bounds or null if rotation point is not set

getFullArea

public Area getFullArea(java.awt.FontMetrics fm)

Description copied from class: RotatedLabelPainter

Returns the area where is label.

Specified by:

getFullArea in class RotatedLabelPainter

Parameters:

fm - font metrics

Returns:

the bounding area of label

paint

public void paint(AbstractGraphics g,
                  Rectangle2D r)

Paints text (possibly rotated) into specified rectangle using provided graphics context.

Specified by:

paint in interface AbstractTextPainter

Overrides:

paint in class TextPainter

Parameters:

g - current graphics context

r - rectangle where text is painted.
