Hi List,
I trying to change the design of a openlayers gui.
If I used ModifyFeature to allowed the editing of a polygon on a layer,
if you press the delete key from the keyboard it deletes a node.
I am trying to change it so that its possible to to have a button on
javascript dialog to do the same.
I assume it would be case of subclassing the ModifiyFeature control,
adding a click handler and faking a keypress event and calling
handleKeypress
So far my solution is to say something like this, I had assumed that
the clickHandler would be called, but it seems to be ignored. I am
calling this as a control argument in the clickHandler set up, since
FOOModifyFeature is a Control, it get invoked, not nothing ever happens.
Does anybody have an idea what I am doing wrong?
FOOModifyFeature=OpenLayers.Class(OpenLayers.Control.ModifyFeature, {
//initialize:function(layer,options){
initialize:function(options){
console.log("3:ZZZZZZZZZZZZZZZZZZZZZZZZZZXXXX: mod
feature "+options);
OpenLayers.Control.ModifyFeature.prototype.initialize.apply(this,[options]);
console.log("Code setup");
var handlerOptions={
'single': true,
'double': false,
'pixelTolerance': 0,
'stopSingle': false,
'stopDouble': false
};
// need to include an extra handler to get a click event.
var clickHandler= new OpenLayers.Handler.Click(
this,{'click':this.onClick},handlerOptions);
},
onClick:function(evt){
console.log("E "+ evt.xy);
},
CLASS_NAME: "FOOModifyFeature"
});
