Changed Target to 1.99 RC 1.
since you know what needs to be done ... ;)
Changing target to FUTURE, since this is not one of the base widgets for 1.99.
The ZoomSelectedLayers widget zooms to the extents of a selected layer. The code looks for the layer metadata "SELECTED" to be "1". Here's an example widget def: <!-- ZOOMSELECTEDLAYERS --> <td><cwc2 type="ZoomSelectedLayers" visible="true" imagetip="Zoom to selected layers" image="icons/icon_zoomactive.png" styleresource="NavButtons" imagewidth="24" imageheight="24"> <image state="normal"/> <image state="hover"/> <image state="selected"/> </cwc2></td> Also: - the layer MUST be queryable - there is a BUFFER parameter that can be set. Valid values are 0 - 100, 1 is the default. It is a percent value. - do NOT include this in the Toolset...unless u want an enless loop of fun
