[OpenLayers-Users] IE6 / OpenLayers / Path DrawFeature and DoubleClicks

[James.Sewell at lisasoft.com]

Thanks for the help Andreas,



I tried using setTimer , but this resulted in intermittent results (depending on the timing of each line draw I believe) and a flickering circle in all broswers.



A simplified version of the code I am using is as below (I have omitted the map with a toolbar).  I hope it isn't too convoluted!



When using IE and using a polyline tool to draw a line (a circle with a diameter of 10 will be drawn around the last point) a double click will not terminate the line (single then wait then double is needed).



Please note I am using an array stored in e.feature.geometry.attributes to store the rangeCircle within the Vector (as passed to the handler in e.feature).



waypointLayer.events.on({'sketchstarted': sketchStarted});

waypointLayer.events.on({'sketchmodified': sketchModified});



function sketchStarted(e)

{

      e.feature.geometry.attributes = new Array();

      e.feature.geometry.attributes['circle'] = createCircle(e.feature.geometry.getVertices());

}



function sketchModified(e)

{

      e.feature.geometry.attributes['circle'].destroy();

      e.feature.geometry.attributes['circle'] = createCircle(e.feature.geometry.getVertices());

      waypointLayer.addFeatures(e.feature.geometry.attributes['circle']);

}



function createCircle(vert)

{

      return new OpenLayers.Feature.Vector(

            OpenLayers.Geometry.Polygon.createRegularPolygon(vert[vert.length-1], 10, 50)

      );

}



Any help would be really appreciated!

Cheers,

I think the "if" part in the above sentence screws your application.

This sounds like an application issue. You could try to draw the other

element in the sketchmodified handler using setTimeout. If that does

not work, try to create a minimal example that shows the issues, so it

will be easier for others to help.

Andreas.
