 * KArtsWidget provides a simple way to treat Arts::Widget classes like
 * native Qt widgets. Suppose you use Qt, and want to put an Arts::Widget
 * type into a layout, you can do so using this code
 *
 * <pre>
 *    Arts::Widget widget = ...get widget from somewhere...;
 *    KArtsWidget *w = new KArtsWidget(widget, this);
 *    layout->addWidget(w);
 * </pre>
 *
 * In line 2 of the code, the "this" is the parent widget (which is usually
 * this in Qt code).
 *
 * The KArtsWidget class keeps a reference to the content widget, so the
 * content widget will not be freed until the KArtsWidget gets destroyed.
