Method Details

drawText

public static void drawText(Graphics2D gr,
 Point2D p1,
 Point2D p2,
 Point2D p3,
 String text,
 Draw.Align hori,
 Draw.Align vert)

Draws a multitude of text lines in an arbitrary angle. Uses LineBreakMeasurer to split the text into lines, and AffineTransform for calculating the text positions. The positions can be described like this:

                        ____----* p2
                ____----  R S T
         ____----  E  F I
p1*----   T L I N
    \T E X
     \
      v
       * p3

Parameters:

gr - The graphics to draw to.

p1 - left point of the top line of the text block

p2 - right point of the top line of the text block

p3 - left point of the last line of the text block (may be overstepped if necessary!)

text - text to write

hori - horizontal alignment

vert - vertical alignment

drawText

public static void drawText(Graphics2D gr,
 Point2D p1,
 Point2D p2,
 String text,
 Draw.Align hori,
 Draw.Align vert)

Draws a multitude of text lines in a orthogonal area. Uses LineBreakMeasurer to split the text into lines. The positions can be described like this:

    --------------*p2
   | bla bla bla  |  
   |     foo      |  
   |              |  
 p1*-------------- 

Parameters:

gr - The graphics to draw to.

p1 - left point of the bottom line of the text block

p2 - right point of the top line of the text block (may be overstepped if necessary!)

text - text to write

hori - horizontal alignment

vert - vertical alignment

drawLine

public static void drawLine(Graphics gr,
 Point2D f,
 Point2D t)

Draws a line between two points.

drawArrowPoints

public static void drawArrowPoints(Graphics gr,
 Point2D head,
 Point2D feathers,
 double len,
 double wid)

Draws a line with one arrow head between two points. Employs Geom.arrowEdges(Point2D,Point2D,double,double).

Parameters:

gr - The graphics to draw to.

head - the point with the arrow head

feathers - the point with no head

len - the depth of the arrow head

wid - the width of the arrow head

copyCoordinates

public static void copyCoordinates(Rectangle2D rect,
 JComponent comp)

copies all coordinates, both position and size.

Parameters:

rect - defines the coordinates

comp - gets new coordinates

copyCoordinates

public static void copyCoordinates(Point2D pos,
 JComponent comp)

copies the position.

Parameters:

pos - defines the position

comp - gets a new position

getCoordinates

public static Rectangle2D.Double getCoordinates(JComponent comp)

delivers the coordinates as a rectangle
