    <p>The event dispatcher will forward mouse events to the listeners registered to the component that is returned by the package-level <code>getMouseEventTarget</code> method in <code>Container</code>. This will be called on your <code>JFrame</code>, and, as the JavaDoc indicates, it:</p> <blockquote> <p>Fetchs the top-most (deepest) lightweight component that is interested in receiving mouse events.</p> </blockquote> <p>The event dispatcher then takes this top-most component (your <code>JTextField</code>, for example) and sends events to all of its listeners only. They do this in order to avoid having to broadcast these events to all of the components that may be layered within a Swing container. MouseEvents, as you can imagine, are very chatty, what with all of the <code>mouseEntered</code>, <code>mouseDragged</code>, and <code>mouseMoved</code> events that are dispatched for all of the <code>MouseListener</code> and <code>MouseMotionListener</code> implementations potentially out there. The processing to find all listeners and then fire events to all of them in the hierarchy would be time consuming.</p> <p>The assumption is also that for classes like <code>JTextField</code> and <code>JButton</code>, etc., the default mouse handling is all that one would need. If you want to handle mouse actions differently (ie, changing color on a <code>mouseEntered</code>/<code>mouseExited</code>), you can add a <code>MouseListener</code> to these widgets as you need to. </p> <p>For your processing, I would suggest simply adding your <code>JPanel</code> as a <code>MouseListener</code> to your top level components if you need to handled these events.</p>

    1. CO+1 Interesting; `getMouseEventTarget()` has _package-private_ (no explicit modifier) access in `java.awt`, but most IDEs allow browsing the source.

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.
