is there a ClearPolygons Widget?

["Delfos, Jacob" <jacob.delfos (at) maunsell.com>]

Jojin,
 
The highlight is simply a polygon layer that is added to the map. When
the map is updated (submit), it appears in the legend as an entry
("Queryresult"). If you have a legend with tickboxes, it can simply be
turned off. You would have to modify line 525 in searchresults.phtml,
though. I may have accidentally put layer status to MS_DEFAULT. I think
I should have made it "MS_ON". Not sure why I did that...
 
I have not yet built functionality to remove the layer permanently. It
wouldn't be hard, though. Just build a widget that changes the status to
MS_DELETE:
 
            $queryResultlayer->set( "status", MS_DELETE );
 
regards,
 
Jacob

	Hello there.
	 
	There is a functionality in my mapserver application that uses
the LocateByAttribute widget to search a polygon layer. After the search
succeeded and a polygon is highlighted in the map and I am satisfied
with the result, I wanted to clear the polygon/s.
	 
	Is there a widget to clear all the selected polygons in a map?
	 
	 
	Thanks and regards.
	 
	Jojin
