I have a map where I load a vector polygon layer (crops) with source data
coming from a database in WKT format. The layer is loaded when a button on the
interface is pressed. I add DrawFeature, ModifyFeature and SelectFeature
controls to the layer, which are selectively activated when a button on the
interface is pressed.
...
map.addLayer(crops);
cropControls = {
dpoly: new
OpenLayers.Control.DrawFeature(crops,OpenLayers.Handler.Polygon,
{displayClass: "olControlDrawFeaturePoint", title:
"Draw Features", handlerOptions: {holeModifier: "altKey"}}),
modify: new
OpenLayers.Control.ModifyFeature(crops,{displayClass: "olControlModifyFeature",
title: "Modify Features"}),
delf: new OpenLayers.Control.SelectFeature(crops, {onSelect:
function(feature) {feature.attributes.pstate = "del";
feature.style = del_style;
crops.drawFeature(feature);
}
}
)
};
for(var key in cropControls) {
map.addControl(cropControls[key]);
}
...
function newcrop() {
var val = "dpoly";
for(key in cropControls) {
var crcontrol = cropControls[key];
if(val == key) {
crcontrol.activate();
} else {
crcontrol.deactivate();
}
}
crops.onFeatureInsert = function(feature) {...}
}
My problem is that the DrawFeature control does not display the draw symbol
(default circle) until after I digitise the first point.
How can I get the circle showing underneath my mouse cursor as soon as the
DrawFeature control is activated?
Many thanks,
Robert Sanson
