How to temporarily hide / show layers

[bclay1297]

How to temporarily hide layers from the map to help declutter other layers. Some layers are image layers and others are feature layers.
I have tried all the examples I could find on line but none work

[gwaldron]

layer->setVisible(false);

That worked for the image layers after casting the GDALImageLayer to an ImageLayer since ImageLayer has a SetVisible.

Not all data is loaded using a FeatureModelLayer . I have not found a way to cast to some feature class that has a setVisible.

If I convert everything to FeatureModelLayer will I still be able to "pick" objects to get their metadata?

No cast necessary; setVisible is a member of VisibleLayer.
The hierarchy is Layer > VisibleLayer > TileLayer > ImageLayer > GDALImageLayer

I am using getLayerByName which is osgEarth::Layer in this routine. setVisible is not a member of osgEarth::Layer. Similar problems rise from the Feature side. I could get the output of the FeatureCursor used for filtering to go into the FeatureModelLayer. so there is no setVisible on that side

Map::getLayerByName<> is a templated function that will automatically cast to the requested type:

auto visibleLayer = map->getLayerByName<VisibleLayer>("name");

This will work an any layer type that derives from VisibleLayer (including FeatureModelLayer).

That seems to work properly in my app for images but not for features presumabley because I cannot get them in a FeatureModelLayer
I will open a separate query for that issue
