    <p><strong>Background information:</strong></p> <p>I am implementing a visual diagram editor, which consists of</p> <ul> <li>different complex elements (re-sizable, with title bar, sub-elements) and</li> <li>different simple elements (not re-sizable, no title bar, no sub-elements).</li> </ul> <p>All elements are draggable.</p> <p>I am using JInternalFrame (for complex elements) along with JPanel (for simple elements) to represent elements of a schematic diagram. There is a container (either a JDesktopPane or a JLayeredPane), which contain all these elements.</p> <p><strong>I have several problems with this concept:</strong></p> <p><strong><em>Case 1</em> - The container is a JDesktopPane:</strong></p> <ul> <li>JInternalFrames are always above other elements.</li> <li>Clicking other elements don't "deactivate" previously active JInternalFrame</li> </ul> <p><strong><em>Case 2</em> - The container is a JLayeredPane:</strong></p> <ul> <li>After clicking some elements inside a JInternalFrame, it stays "activated" forever.</li> </ul> <p><strong><em>Case 3</em> - JInternalFrame used for everything, but without decoration for simple elements:</strong></p> <ul> <li>My custom border <em>(which is needed when I manually remove JInternalFrame's title bar)</em> is every time replaced by current LAF border, after activating/deactivating the JInternalFrame.</li> </ul> <p>I don't get the whole concepts behind activating JInternalFrames anyway. <strong>If I could make a JInternalFrame not activable at all</strong>, I could choose <strong><em>Case 2</em></strong> any would be happy.</p> <p>Please advice me, what would be an simple and straightforward solution to given problems.</p> <p><strong>NOTE: Selection of components and activation of JInternalFrame seem to be different things.</strong></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.
