<p>This record mapper shows a number of "fields" for each "record" and how they are mapped between each other.</p>
|
|
<p>
|
|
Draw new links by dragging from the background of any field.
|
|
Reconnect a selected link by dragging its diamond-shaped handle.
|
|
The "record" Nodes use a <a>Panel.Table</a> to place the various fields into rows.
|
|
Records are not movable or copyable or deletable.
|
|
</p>
|
|
<p>For a variation on this sample with selectable fields in the record nodes, see the <a href="selectableFields.html">selectable fields</a> sample.</p>
