Chris something that came into my mind was the use of queryMap. I had not used it since eternities because it became obsolete to me using the p.mapper highlighting method. I made a quick test and it would need just a few lines in query.php and map.php to change/add.
Note that this will only work for selects, not identifies or searches (this would require some more changes). And I have currently no plans for changing to this solution, it might be faster in case of lots returned values, but has less flexibility. And it would not work with the current way of searching in Postgis layers. If you're interested, I put the files at http://www.pmapper.net/dl/querymap.zip You need to define a querymap entry in the map file like QUERYMAP COLOR 255 255 0 STATUS on STYLE hilite END also set <highlightSelected> in the XML config file to 0. I have not modified anything to remove the highlight but I can tell you what to modify in case you would like to use this solution. armin On 24/08/2010 16:58, Chris Jackson wrote: > Hi all > > One of the underlying datasets in my P.Mapper app is a model grid (many > thousand cells) in a shapefile.
