getPixelFromEvent fails in some cases (margin, border, text-align)

[crschmidt]

IE's different CSSSS model means that there are some cases where IE fails to report the correct mouse position. This can be seen in a number of ways -- digitizing features, mouseposition control, etc. Typically, these problems can be solved by using different CSS.

The CSS properties which have been reported to cause problems:

• Border on map element
• Margin on map element
• text-align on map element

The code to fix/improve is OpenLayers.Events.getMousePosition, and possibly OpenLayers.Util.getPagePosition.

There is no firm plan to fix this in the short term.

This doesn't only happen with IE.

The following example code includes a map with a cross drawn at lonlat(0,0) but the coordinates shown in the mousePosition control differ from the expected ones.

            map = new OpenLayers.Map('map');
            var layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
                    "http://labs.metacarta.com/wms/vmap0", {layers: 'basic'} );
            map.addLayer(layer);

            vectorLayer = new OpenLayers.Layer.Vector();
            
            var line = new OpenLayers.Geometry.LineString([
                new OpenLayers.Geometry.Point(0, -10),
                new OpenLayers.Geometry.Point(0, 10)
            ]);
            var feature = new OpenLayers.Feature.Vector(line);
            vectorLayer.addFeatures([feature]);
            
            var line = new OpenLayers.Geometry.LineString([
                new OpenLayers.Geometry.Point(-10, 0),
                new OpenLayers.Geometry.Point(10, 0)
            ]);
            var feature = new OpenLayers.Feature.Vector(line);
            vectorLayer.addFeatures([feature]);

            map.addLayer(vectorLayer);
            map.zoomToMaxExtent();
            map.addControl(new OpenLayers.Control.MousePosition());
