    <p>So say I have a Jpanel(container) with 3 Jpanels inside, they are in a JPanel ArrayList. Now I want to be able to determine which Panel the mouse is pressed in, and which one the mouse is released in This way I can reorder the panels in the arraylist, and add them back to the container in the new order.</p> <p>I have code currently that works for the swap, but the problem is determining which panels are being swapped. I have now an action listener on each other the inner panels that when pressed, startIndex in the container is set to that index, and endIndex is assigned when the mouse is released. </p> <pre><code>@Override public void mousePressed(MouseEvent e) { con.startIndex = (this); } @Override public void mouseReleased(MouseEvent e) { con.endIndex = (this); con.swap(); } </code></pre> <p>But it always tries to swap with the same panel that the mouse was pressed in. Anyone have any ideas?</p> <pre><code>public void swap() { //This swap code works for the two numbers it's given System.out.println("start swapping"); System.out.println(startSwapIndex + " with " + endSwapIndex); if(startSwapIndex != endSwapIndex){ SpecPanel start = this.getSpecPanel(startSwapIndex); SpecPanel end = this.getSpecPanel(endSwapIndex); panels.set(endSwapIndex, start); panels.set(startSwapIndex, end); removeAllSpecPanels(); addAllSpecPanels(); System.out.println("swap complete"); } } </code></pre> <p>Thanks.</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.
