Mám niečo takéto http://gmaps-samples.googlecode.com/svn/trunk/poly/mymapstoolbar.html využíva to Google maps api 2 ale s tým by problém nemal byť. Keď použijem prvok "línia" spravím líniu, no nenapíše mi jeho dĺžku, napíše ju až keď túto líniu editujem teda chytím napr. koniec a presuniem ho trochu inde. Pri ploche to nerobí tá je OK. Už sa s tým trápim dlhšie, no na chybu som neprišiel. Pridám sem aj kód. Vopred ďakujem za každú radu.

function select(buttonId) {
  document.getElementById("hand_b").className="unselected";
  document.getElementById("shape_b").className="unselected";
  document.getElementById("line_b").className="unselected";
  document.getElementById("placemark_b").className="unselected";
  document.getElementById(buttonId).className="selected";
}

function stopEditing() {
  select("hand_b");
}

function getColor(named) {
  return COLORS;
}

function getIcon(color) {
  var icon = new GIcon();
  icon.image = "http://google.com/mapfiles/ms/micons/" + color + ".png";
  icon.iconSize = new GSize(32, 32);
  icon.iconAnchor = new GPoint(15, 32);
  return icon;
}

function startShape() {
  select("shape_b");
  var color = getColor(false);
  var polygon = new GPolygon([], color, 2, 0.7, color, 0.2);
  startDrawing(polygon, "Shape " + (++shapeCounter_), function() {
    var cell = this;
    var area = polygon.getArea();
    cell.innerHTML = (Math.round(area / 10000) / 100) + "km<sup>2</sup>";
  }, color);
}

function startLine() {
  select("line_b");
  var color = getColor(false);
  var line = new GPolyline([], color);
  startDrawing(line, "Line " + (++lineCounter_), function() {
    var cell = this;
    var len = line.getLength();
    cell.innerHTML = (Math.round(len / 10) / 100) + "km";
  }, color);
}

function addFeatureEntry(name, color) {
  currentRow_ = document.createElement("tr");
  var colorCell = document.createElement("td");
  currentRow_.appendChild(colorCell);
  colorCell.style.backgroundColor = color;
  colorCell.style.width = "1em";
  var nameCell = document.createElement("td");
  currentRow_.appendChild(nameCell);
  nameCell.innerHTML = name;
  var descriptionCell = document.createElement("td");
  currentRow_.appendChild(descriptionCell);
  featureTable_.appendChild(currentRow_);
  return {desc: descriptionCell, color: colorCell};
}

function updateMarker(marker, cells, opt_changeColor) {
  if (opt_changeColor) {
    var color = getColor(true);
    marker.setImage(getIcon(color).image);
    cells.color.style.backgroundColor = color;
  }
  var latlng = marker.getPoint();
  cells.desc.innerHTML = "(" + Math.round(latlng.y * 100) / 100 + ", " +
  Math.round(latlng.x * 100) / 100 + ")";
}

function initialize() {
  if (GBrowserIsCompatible()) {
    map = new GMap2(document.getElementById("map"));
    map.setCenter(new GLatLng(37.4419, -122.1419), 13);
    map.addControl(new GSmallMapControl());
    map.addControl(new GMapTypeControl());
    map.clearOverlays();
    featureTable_ = document.getElementById("featuretbody");
    select("hand_b");
  }
}
