ActiveX Control: boolean selectPolygon(MGMapLayer layer, MGCollection latlon)
Plug-In/Java Edition: boolean selectPolygon(MGMapLayer layer, Vector latlon)
Plug-In/Java Edition: boolean selectPolygon(MGMapLayer layer, Vector lat, Vector lon)
Selects all map features that fall within the specified polygon.
For compatibility between the Autodesk MapGuide Viewer Plug-In, Java Edition, and ActiveX Control, use selectPolygonEx instead of selectPolygon.
Note that this method does not work during a busy state. For additional information about the busy state, refer to "Handling Busy State and Map Refresh" chapter in the Autodesk MapGuide Developer's Guide.
layer - Map layer containing the features to select, or null to select from all layers. A map layer must be selectable for any features on it to be selected.
latlon - A java.util.Vector (or MGCollection) object used to stored the list of latitude/longitude pairs represented by MGPoint objects.
lat - A java.util.Vector object used to store the list of latitude (Y) values of polygon vertices represented by java.lang.Double objects (Plug-In and Java Edition only).
lon - A java.util.Vector object used to store the list of longitude (X) values of polygon vertices represented by java.lang.Double objects (Plug-In and Java Edition only).
boolean - Returns True if successful; otherwise, returns False.
-1 (busy)
