Class GridFlowLayout

java.lang.Object
  org.nuiton.widget.GridFlowLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2

public class GridFlowLayout
extends java.lang.Object
implements java.awt.LayoutManager2

Ce layout place les composants de gauche à droite ou de droite à gauche selon la valeur de Component.getComponentOrientation(). Si un composant n'a pas assez de place pour se mettre sur la ligne courant, il est mis sur la ligne suivante et les composants sont redimensionnés pour prendre le maximum de place disponible sur la ligne. Si le container est dans un JViewport (ou JScrollPane), ce layout essai de ne jamais faire apparaitre le ScrollBar horizontal.

Tous les composants ont la même taille.
