我使用的開發工具是IBM的Rational Application Developer里的eclipse,不知道怎麼會這樣？？
求大神指導啊

shapeButton.addActionListener(new ActionListener(){
   public void actionPerformed(ActionEvent e){
    ShapeWindow shapeWindow = new ShapeWindow(DrawPictureFrame.this);
    int shapeButtonWidth = shapeButton.getWidth();
    int shapeWindowWidth= shapeWindow.getWidth();
    int shapeButtonX= shapeButton.getX();
    int shapeButtonY=shapeButton.getY();
    int shapeWindowX = getX() +shapeButtonX - (shapeWindowWidth - shapeButtonWidth)/2;
    int shapeWindowY = getY()+ shapeButtonY + 80;
    shapeWindow.setLocation(shapeWindowX,shapeWindowY);
    shapeWindow.setVisible(true);
   }
