Description
This Control is an enhanced version of Control/PanZoomBar. Clicking on the Query button (third button with "i" inside) you'll activate this function:
- Click on a map to query all queryable layers
- Queryable layers are signed with a "(q)" in the legend.
- An AJAX call is made to all WMS server to get text/html output
- the output is redirected to the queryTarget object.
code sample
//set the target div for query output
var queryTarget = $('queryOut');
//create the Control
WMSToolbar = new OpenLayers.Control.WMSToolbar({queryTarget: queryTarget});
// add control to map instance
map.addControl(WMSToolbar);
know bugs or open issues
- QueryByRect is returning a stupid alert message. should be better to have a QueryByPoint on the center of the rectangular.
- Query are made only in text/html mode. Would be better to offer a GML parser or a way to choose the mode.
