[OpenLayers-Dev] [OpenLayers-Users] Delete Feature

[Benoit PESTY]

Hello,

I've mixed the mailing lists, I'm lost in my own mails, sorry for the disturbance.

Thanks to your example Arnd, I've come up with an ugly solution to my problem.

I've changed my delete method like this:
/**
 * Delete a feature
 */
function deleteFeature(feature) {
    modifyTool.unselectFeature(feature);   // modifyTool is my ModifyFeature Control 
    getEditableLayer().removeFeatures(feature);
}

But it's not very satisfying. It seems that the ModifyFeature control register the "featureselected" event on the layer and generate some temporary vertices event is the control should be disabled (in the toolbar it is toogled off). The cleaner solution would be to generate theses vertices only the the control is on.

Hi,

i have enhanced the ModifyFeature Control, so that I can delete a feature
with the key 'k' like kill.

OpenLayers.Control.ModifyFeature.prototype.deleteCodes = [46, 100, 107]; 
//Backspace, d, k
OpenLayers.Control.ModifyFeature.prototype.handleKeypress = function(code) {

...
...
...

        else if(this.feature && OpenLayers.Util.indexOf(this.deleteCodes,
code) != -1 && code == 107)
        {
            var obj = this.feature;
            var lyr = obj.layer;
            this.unselectFeature(obj);
            lyr.removeFeatures(obj);
            msg ="201:" + code;
        }
        //alert(msg);
}

    Hello,

    I have a stupid error when trying to delete a vector feature. I've updated OpenLayers from 2.5 to 2.6 (latest from trunk) and when trying to delete a feature I have the corners of the polygon that stay on the map.

    I've added a control like this :

    // Delete feature
    var deleteTool = new OpenLayers.Control.SelectFeature(layer_vector,
    {
               onSelect:deleteFeature,
    });

    And the called method is like this :
    function deleteFeature(feature) {
        getEditableLayer().removeFeatures(feature);
    }


    The problem seems to be that when getting the vector layer (thru the getLayersByName() method) the feature is set to "modification mode".

    I've tried to look around for the "renderIntent" property of the selectfeature control but I don't know the clean way to use it.

    Thanks,

    Benoit Pesty
