public class WPopupWidget
extends WCompositeWidget
Base class for popup widgets.

A popup widget anchors to another widget, for which it usually provides additional information or assists in editing, etc...

The popup widget will position itself relative to the anchor widget by taking into account available space, and switching sides if necessary to fit the widget into the current window. For example, a vertically anchored widget will by default be a "drop-down", positioning itself under the anchor widget, but it may also choose to position itself above the anchor widget if space is lacking below.
