<dvt:predefinedTheme>

predefinedTheme predefined theme


The <dvt:predefinedTheme> tag renders a an existing theme on the map. A predefined Theme is a layer that is defined using the Map adminstrator tool and is stored along with the map metadata in the database. The predefined theme tag is used when you have your own custom Map Viewer instance and need to display large datasets that can be rendered directly by MapViewer. No model class exists for the predefined theme as the data for the layer is rendered by MapViewer.

Model

The predefinedTheme tag does not have any model associated with it.

Example

<dvt:map ...map attributes...>
    <dvt:predefinedTheme id="predefinedTheme1"
                         themeName="MVDEMO.NEW_THEME_DEMO_STATES_DENSITY"/>
</dvt:map>

Attributes

Name Type Supports EL? Description
id java.lang.String no The identifier for the component
themeName java.lang.String yes Specifies the predefined theme on which this theme layer is based. The theme must come from the same data source as the base map. The theme is defined in mapbuilder. For detail, refer to the documentation of mapviewer.
shortLabel java.lang.String no Specifies the label of this theme on the legend. If the attribute is not specified, the id of the theme will be used as the label on the legend.

maxZoom int no Specifies the maximum zoom scale where this theme will still be visible.
selectionListener java.lang.String no a method reference to a selection listener Refers to a backing bean method that takes MapSelectionEvent as an argument. The MapSelectionEvent contains the information on the selected region. Sample code: 
public void processSelection(MapSelectionEvent mapSelectionEvent) {
    Iterator iterator = mapSelectionEvent.getIterator();
        
    while (iterator.hasNext())
    {
        DataContent dt = (DataContent)iterator.next();    
        String selectedLocation = dt.getLocationName();
        System.out.println (selectedLocation);
    }                        
}
clickAction java.lang.String no Refers to a backing bean method that performs navigation processing for the map and returns an outcome String. Or a static outcome String can be specified.

The application writes the Navigation rules.
clickListener java.lang.String no a method reference to a click listener Refers to a backing bean method that takes MapClickActionEvent as an argument. The MapClickActionEvent contains the information on the clicked point. Sample code: 
public void processMouseClick(MapClickActionEvent mapClickActionEvent) {
    if (mapClickActionEvent.getDataContent() != null)
    {
        DataContent dt = mapClickActionEvent.getDataContent();
        System.out.println ("Location Name: " + dt.getLocationName());
    }
        
    System.out.println("MouseX " + mapClickActionEvent.getMouseX()); 
    System.out.println("MouseY " + mapClickActionEvent.getMouseY());         
}
leftClickBehavior java.lang.String no Specifies the behavior when user left clicks on an element of a theme. Valid value of theme are:
  • "Action" - An action event will be fired.
