<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Guys,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have been able to build a control to freehand digitize a
polygon and then launch a function to use the polygon as a search polygon in a
WFS request. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This works for me:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>drawControls = new OpenLayers.Control.DrawFeature(vectorLayer,
OpenLayers.Handler.Polygon) ;<o:p></o:p></p>
<p class=MsoNormal>
// extend the drawcontrol with its behavior<o:p></o:p></p>
<p class=MsoNormal>
OpenLayers.Util.extend(drawControls, <o:p></o:p></p>
<p class=MsoNormal>
{
draw: function (){<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.5in'>this.polygon = new
OpenLayers.Handler.Polygon(drawControls,{"done":
this.notice});
this.polygon.activate();},<o:p></o:p></p>
<p class=MsoNormal>
notice: function (polygon)<o:p></o:p></p>
<p class=MsoNormal>
{<o:p></o:p></p>
<p class=MsoNormal>
// get vertices of polygon into and array of coordinate pairs<o:p></o:p></p>
<p class=MsoNormal>
var polyString = polygon.toString() ;<o:p></o:p></p>
<p class=MsoNormal>
<o:p></o:p></p>
<p class=MsoNormal>
// do whatever with polygon linestring here<o:p></o:p></p>
<p class=MsoNormal style='margin-left:1.0in;text-indent:.5in'>…
<o:p></o:p></p>
<p class=MsoNormal>
}<o:p></o:p></p>
<p class=MsoNormal>
}); <o:p></o:p></p>
<p class=MsoNormal> map.addControl(drawControls);<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I wanted to use the RegularPolygon feature to do the same
but it does not launch the function in the same way after the vector geometry
is successfully created. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>var polyType = 6;<o:p></o:p></p>
<p class=MsoNormal>var rad = ‘’;<o:p></o:p></p>
<p class=MsoNormal>polyOptions = {sides: polyType, radius: rad, angle: 0}<o:p></o:p></p>
<p class=MsoNormal>shapeControl = new
OpenLayers.Control.DrawFeature(vectorLayer, OpenLayers.Handler.RegularPolygon,
{handlerOptions: polyOptions});<o:p></o:p></p>
<p class=MsoNormal>
// extend the shapeControl with its behavior<o:p></o:p></p>
<p class=MsoNormal>
OpenLayers.Util.extend(shapeControl, <o:p></o:p></p>
<p class=MsoNormal>
{
draw: function (){<o:p></o:p></p>
<p class=MsoNormal>
this.polygon = new OpenLayers.Handler.RegularPolygon(shapeControl,
{"done": this.notice}); this.polygon.activate();},<o:p></o:p></p>
<p class=MsoNormal>
notice: function (polygon)<o:p></o:p></p>
<p class=MsoNormal>
{<o:p></o:p></p>
<p class=MsoNormal>
// get vertices of polygon into and array of coordinate pairs<o:p></o:p></p>
<p class=MsoNormal>
var polyString = polygon.toString() ;<o:p></o:p></p>
<p class=MsoNormal>
// do whatever with polygon linestring here<o:p></o:p></p>
<p class=MsoNormal>
…
<o:p></o:p></p>
<p class=MsoNormal>
}<o:p></o:p></p>
<p class=MsoNormal>
});<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>In both cases the polygon is created and drawn to the
vectorLayer.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone see anything obviously wrong with the second
piece of code?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Cheers,<o:p></o:p></p>
