public class Label

extends FigText

implements java.io.Serializable

Label: a basic label on a SimObject's symbol.

This class is realized as a subclass of FigText with specific attributes: layer 10, color red, SansSerif 10pt, left aligned and may be subclassed for other attributes.

Label

public Label()

construct an empty Label.

Method Detail

initialize

public boolean initialize(java.lang.String s)

initialize an Label from a String. The String contains either the x and y coordinates and the label String or the x and y coordinates, and alignment index, and the label String, or a 6 attributes format:
x y label
x y 3 label
x y align FIG_font_index size color_rgb label
The possible alignments are 1 (left), 2 (center), and 3 (right). Example: (16=FIG Helvetica, 27=27, 36864=0x009000=green4
"1200 2400 2 16 24 36864 my_nice_label"

Specified by:

initialize in interface FigObject

Overrides:

initialize in class FigBaseobject

build_attribs

protected void build_attribs()

writeAsResource

public void writeAsResource(java.io.PrintWriter ps)

Description copied from class: FigBaseobject

default implementation of 'writeAsResource'. This will write a nearly xfig-compatible version of all basic FigObjects.

Specified by:

writeAsResource in interface FigObject

Overrides:

writeAsResource in class FigBaseobject

copy

public FigObject copy()

Description copied from class: FigText

build a copy of this FigText object.

Specified by:

copy in interface FigObject

Overrides:

copy in class FigText

mirrorY

public void mirrorY(int mirror_x,
                    int mirror_y)

mirrorY(): we override the method of our base class FigText, because we don't want to put the text upside down, but just to set a new text base point (text origin). In order to keep the relative position of Labels within Symbols, we try to center the text string inside its bounding box, using the FontMetrics info (ascent, descent, ...).

Specified by:

mirrorY in interface FigObject

Overrides:

mirrorY in class FigText

setTextSource

public void setTextSource(TextSource _textSource)

set the TextSource for deferred repaints on this Label.

If a (non-null) TextSource is specified for a Label, it is no longer necessary to call setText() to change the Label text. Instead, the text to be displayed is fetched from the TextSource every time the Label is paint()ed.

This defers the construction and formatting of the String object and the (costly) accesses to the AWT FontMetrics until the Label is actually used.

setColorSource

public void setColorSource(ColorSource _colorSource)

paint

public void paint(java.awt.Graphics g)

paint this Label to Graphics g.

Note that the String to be displayed by this Label is reconstructed on every repaint, if our TextSource is non-null;

Specified by:

paint in interface FigObject

Overrides:

paint in class FigText

toString

public java.lang.String toString()

toString() - the usual info method

Specified by:

toString in interface FigObject

Overrides:

toString in class FigText
