    <p>I am using JButton's Action listener to draw different shapes.To keep previously drawn shapes on panel all time, I've used an arraylist in which all drawn shapes has added and repaint whole list.How can I drag any shape while others display on Jpanel all the time?</p> <pre><code>protected void paintComponent(Graphics g) { super.paintComponent(g); System.out.println("====&gt;&gt;&gt; " + s); switch (s) { case "Button1": Activity act = new Activity(); act.setArcH(15); act.setArcW(15); act.setBreadth(40); act.setLength(50); act.setXpoint(x); act.setYpoint(y); //========================================================== obj = new ShapePoints(); obj.setShapeId(ShapesID.ROUND_RECTANGLE_ID); obj.setxPoint(act.getXpoint()); obj.setyPoint(act.getYpoint()); obj.setLength(act.getLength()); obj.setBreadth(act.getBreadth()); obj.setArcW(act.getArcW()); obj.setArcH(act.getArcH()); shapePoints.add(obj); Iterator itr = shapePoints.iterator(); while (itr.hasNext()) { ShapePoints sp = (ShapePoints) itr.next(); switch (sp.getShapeId()) { case ShapesID.ARROW_ID: break; case ShapesID.CIRCLE_ID: g.drawOval(obj.getxPoint(), obj.getyPoint(), obj.getLength(), obj.getBreadth()); break; case ShapesID.CON_CIRCLE_ID: g.drawOval(sp.getxPoint(), sp.getyPoint(), sp.getLength(), sp.getLength()); g.fillOval(sp.getxPoint() + 10, sp.getyPoint() + 10, sp.getBreadth() / 2, sp.getBreadth() / 2); break; case ShapesID.RECTANGLE_ID: break; case ShapesID.ROUND_RECTANGLE_ID: g.drawRoundRect(obj.getxPoint(), obj.getyPoint(), obj.getLength(), obj.getBreadth(), obj.getArcW(), obj.getArcH()); break; } } break; </code></pre> <p>this is for 1 button</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
