how to select feature by drawing a line in openlayers? - dictionary

Question

There is one option in openlayers selecting features under the box. But, I want to select the features when I draw line (draw with shift key down-free hand drawing). In my script I already implemented drawing and selecting options. I can draw line and select (multiple) features independently. Now, I want to merge this two. I want to select those features data which are touched by my drawn line. Is there any sample example available?
Here, I have given sample code -
//Selection property---------------------------------------
var selectControl = new OpenLayers.Control.SelectFeature(
[vectorLayer],
{
clickout: true, toggle: true,
multiple: true, hover: false,
toggleKey: "ctrlKey", // ctrl key removes from selection
multipleKey: "shiftKey" // shift key adds to selection
}
);
map.addControl(selectControl);
selectControl.activate();
var draw = new OpenLayers.Control.DrawFeature(
vectorLayer, OpenLayers.Handler.Path,
{displayClass: "olControlDrawFeaturePoint", title: "Draw Features", handlerOptions: {holeModifier: "altKey"}}
);
Thanks, in advance.

You have to register event "sketchcomplete" that will run over all features in layer-bo-be-selected and check if it has shared geometry with line sketched.
Something like this, unfortunately I can't test it now.
vectorLayer.events.register('sketchcomplete', vectorLayer, sketchCompleteFunc);
function sketchCompleteFunc(obj) {
for (var i=0;i<layer-to-be-selected.features.length;i++) {
if (layer-to-be-selected.features[i].geometry.intersects(obj.geometry)) {
selectControl.select(layer-to-be-selected.features[i])
}
}
}
