Highlight interactor

> > > > > >

The highlight interactor allows you to highlight graphic objects when moving the mouse over them. Using Hitmap technology, the highlighting effect can be constructed and displayed on the client side without a round-trip to the server.

JViews provides a JavaServer™ Faces (JSF) component for this interactor. To use the highlight interactor you must first insert the highlight interactor tag into your JSF page.

To define one object, use the following tag:

<jvf:highlightInteractor id="highlightInteractor"/>

You can use the interactor in a <jvf:view> view as follows:

<jvf:view id="viewID" interactorId="highlightInteractor" />

You can use the interactor in a <jvdf:diagrammerView> view as follows:

<jvdf:diagrammerView id="diagramId" interactorId="highlightInteractor" />

The highlight effects are visible when you move your mouse over the graphic objects.

The highlight interactor works with both a <jvf:view> and a <jvdf:diagrammerView> .

The method described in the previous section shows you how to use the highlight interactor with a <jvf:view> and a <jvdf:diagrammerView> . However, you might want to have both the pan interactor and the highlight interactor working at the same time. The interactor group is designed for this purpose.

You can make two interactors work together as follows:

   <jvf:highlightInteractor id="highlightInteractor"/> 
   <jvf:panInteractor id="panInteractor" />
   <jv:interactorGroup id="highlightAndTooltip" interactors="panInteractor highlightInteractor"/>
   <jvdf:diagrammerView id="viewID" interactorId="highlightAndTooltip" />
