两个JTable可以一起滚动的Listener

?h明：kinmuSrl,orderSrlはScrollPaneです。

以下はソ?`スです。

/**二つテ?`プル一?wにスクロ?`ルのためのリスナ?`*/
ChangeListener c1 = new ChangeListener(){
boolean adjflg = false;
public void stateChanged(ChangeEvent e){
  JViewport src = null;
  JViewport tgt = null;
  if(e.getSource()==kinmuSrl.getViewport()){
   src = kinmuSrl.getViewport();
   tgt = orderSrl.getViewport();
  }else if(e.getSource()==orderSrl.getViewport()){
   src = orderSrl.getViewport();
   tgt = kinmuSrl.getViewport();
  }
  if(adjflg || tgt==null || src==null) return;
  adjflg = true;
  Dimension dim1 = src.getViewSize();
  Dimension siz1 = src.getSize();
  Point     pnt1 = src.getViewPosition();
  Dimension dim2 = tgt.getViewSize();
  Dimension siz2 = tgt.getSize();
  Point     pnt2 = tgt.getViewPosition();
  double d;
  d = pnt1.getY()/(dim1.getHeight()-siz1.getHeight())*(dim2.getHeight()-siz2.getHeight());
  pnt1.y = (int)d;
  d = pnt1.getX()/(dim1.getWidth()-siz1.getWidth())*(dim2.getWidth()-siz2.getWidth());
  pnt1.x = (int)d;
  tgt.setViewPosition(pnt1);
  adjflg = false;
}
};

使い方：

ScrollPaneにリスナ?`を付けます。

orderSrl.getViewport().addChangeListener(c1);
kinmuSrl.getViewport().addChangeListener(c1);
