This section describes how to manage layer styles correctly.

Managing Style Parenting

To provide style inheritance (accessible in the Layer Tree Panel), the parent layer style must be a composite style, and you need to manage the style parenting on its own:

IlvMapStyle childStyle=layer.getStyle();
childStyle.setParent(parent.getStyle());

Using Dynamic Styles

When the application uses dynamic styles, you need to access the style controller property of the manager:

IlvMapStyleController themeController = IlvMapStyleControllerProperty.GetMapStyleController(manager);

With the controller, you can decide on specific style settings for scale intervals. For example, to change the layer visibility:

themeController.addTheme(1/100000.0,source.getInsertionLayer(),"Visible");
themeController.getStyle(source.getInsertionLayer(),1/100000.0).setVisibleInView(true);
themeController.getStyle(source.getInsertionLayer(),1/100000.0).setVisibleInOverview(false);

If you use multiple dynamic styles, you have to take care of style inheritance in a slightly more complex way because more than one style is used:

IlvMapDynamicStyle []t=themeController.getThemes(layer);
for (int i = 0; i < t.length; i++) {
  t[i].getStyle().setParent(parent.getStyle());
}

Once this is done, you can apply the style you want to use for the current scale of the view:

themeController.updateTheme(view,layer);

Alternatively, you can setup the theme for all layers in one single call:

themeController.updateCurrentTheme();
