[news.eclipse.tools.gef] Re: laying out child figures in 2 columns

["Felix L J Mayer" <felix.mayer@xxxxxxxxxxxxx>]

Okay, here is your example, I just removed some code that is specific to my 
stacked layout to make it more readable.

public class StackedLayout extends AbstractLayout {

  /**
   * @see 
org.eclipse.draw2d.AbstractLayout#calculatePreferredSize(org.eclipse.draw2d.IFigure, 
int, int)
   */
  protected Dimension calculatePreferredSize( IFigure container, int wHint, 
int hHint ) {
    Dimension preferred = new Dimension( 0, 0 );
    if( container.isVisible() ) {
      for( Iterator i = container.getChildren().iterator(); i.hasNext(); ) {
        IFigure child = (IFigure) i.next();
        Dimension current = child.getPreferredSize();
        // compute preferred here
      }//for
      Insets insets = container.getInsets();
      preferred.expand( insets.getWidth(), insets.getHeight() );
    }//if
    return preferred;
  }//calculatePreferredSize()

  /**
   * @see 
org.eclipse.draw2d.LayoutManager#getMinimumSize(org.eclipse.draw2d.IFigure, 
int, int)
   */
  public Dimension getMinimumSize( IFigure container, int wHint, int hHint ) 
{
    // Compute the minimum size as the preferred size of the first
    // Compartment, which should be the title of the classifier.
    return ((IFigure) container.getChildren().get( 0 )).getPreferredSize();
  }//getMinimumSize()

  /**
   * @see 
org.eclipse.draw2d.AbstractLayout#layout(org.eclipse.draw2d.IFigure)
   */
  public void layout( IFigure container ) {
    Rectangle clientArea = container.getClientArea();
    LOG.finest( "container=" + container + " clientArea=" + clientArea );
    int maxHeight = clientArea.height;
    Rectangle previous = new Rectangle( clientArea.x, clientArea.y, 
clientArea.width, 0 );
    for( Iterator i = container.getChildren().iterator(); i.hasNext(); ) {
      IFigure child = (IFigure) i.next();
      Rectangle bounds = // Whatever you need, previous probably helps
      child.setBounds( bounds );
      previous = bounds;
    }//for
  }//layout()

}
