Class LpexStickyHoverManager

java.lang.Object
  InformationControlReplacer
      com.ibm.lpex.alef.LpexStickyHoverManager

public class LpexStickyHoverManager
extends InformationControlReplacer

Implements a sticky hover control, i.e. a control that replaces a hover with an enriched and focusable control.

The information control is made visible on request by calling showInformationControl(Rectangle).

Clients usually instantiate and configure this class before using it. The configuration must be consistent: This means the used IInformationControlCreator must create an information control expecting information in the same format the configured IInformationProviders use to encode the information they provide.
