Hi George
Here is how I specify the controls:
//Select, Draw and Modify controls - these are specific to the layer
controls = {
select: new OpenLayers.Control.SelectFeature(crops, {callbacks:
{'over':feature_info}}),
dpolygon: new
OpenLayers.Control.DrawFeature(crops,OpenLayers.Handler.Polygon),
modify: new OpenLayers.Control.ModifyFeature(crops),
delf: new OpenLayers.Control.SelectFeature(crops, {onSelect:
function(feature) {crops.destroyFeatures([feature])}})
//delf: new OpenLayers.Control.SelectFeature(crops, {onSelect:
function(feature) {feature.geometry.destroy();crops.eraseFeatures([feature])}})
};
for(var key in controls) {
map.addControl(controls[key]);
}
Then I have a function that responds to radio buttons in a div outside the map
that sets the mode and activates or deactivates the controls:
function toggleControl(element) {
mode = element.value;
OpenLayers.Util.getElement('comments').innerHTML = "Mode:" + mode;
if ((mode == "select") || (mode == "modify")){
crop_style.strokeColor = "#0000ff";
}
else {
crop_style.strokeColor = "#ff0000";
}
for(key in controls) {
var control = controls[key];
if(element.value == key && element.checked) {
control.activate();
} else {
control.deactivate();
}
}
crops.onFeatureInsert = function(feature) {
feature.attributes.prop0 = 'new'; //This should be modified to
get actual ID
alert("New crop area inserted");
}
}
Hope that helps.

Dear List,
I am having trouble trying to capture events when the ModifyFeature control
is activated and deactivated.
I define my control as such:
modify = new
OpenLayers.Control.ModifyFeature(lyrPlanning,{'displayClass':
'olControlModifyFeature',
'mode': OpenLayers.Control.ModifyFeature.RESHAPE |
OpenLayers.Control.ModifyFeature.DRAG |
OpenLayers.Control.ModifyFeature.ROTATE});
I try to register the event like this:
modify.events.register('deactivate',modify,modify_deactivated);
this last line causes a syntax error!
I had already defined
function modify_deactivated() {alert('!');}"
I have that feeling that I am doing something so silly I will never get it.
Appreciate any help
George Mu'ammar
