showLayer

Note: The SetLayer command in legacy Maintain has been replaced by the IbComposer_showLayer command in Maintain Data. The IbComposer_showLayer command allows layers to be set as visible or invisible at run time. It is used in a JavaScript event.

Use the showLayer Command

IbComposer_showLayer(layername,bShow);

where:

layername

Alphanumeric

Is the name of the layer, which will be shown or hidden.

bShow

Is an operator that can be set to true to show the layer or false to hide it.
