 {
     // parent -> child
     public final DimensionBox dimension;

     public final AlignBox align;

     public final Box content;

     public FramedBox(Box child)
     {
         // child -> parent
         content = child;

Method Details

calculateDimension

protected void calculateDimension()

Description copied from class: Box

Berechnet rekursiv die Abmessung (die Höhe und Breite) der eigenen Box.

Single-Child-Code-Beispiel

 
 protected void calculateDimension()
 {
     width = child.width + 2 * margin;
     height = child.height + 2 * margin;
 }
  

Multiple-Child-Code-Beispiel

 
 protected void calculateDimension()
 {
     int maxWidth = 0;
     for (Box child : childs)
     {
         if (child.width > maxWidth)
         {
             maxWidth = child.width;
         }
         height += child.height;
     }
     width = maxWidth;
 }

calculateAnchors

protected void calculateAnchors()

Description copied from class: Box

Berechnet rekursiv alle Ankerpunkte (linkes unteres Eck) der untergeordneten Kinder-Boxen. Die inneren Blattboxen brauchen diese Methode nicht zu implementieren.

Single-Child-Code-Beispiel

 
 protected void calculateAnchors()
 {
     child.x = x + margin;
     child.y = y + margin;
 }
  

Multiple-Child-Code-Beispiel

 
 protected void calculateAnchors()
 {
     int yCursor = y;
     for (Box child : childs)
     {
         child.x = x;
         child.y = yCursor;
         yCursor += child.height;
     }
 }
