Drawtoolbar Default Shape Size

JamieSimko

When you click to draw predefined shapes such as Triangles, Circles, Arrows, and Ellipses (As shown by this example) there is a default size that they get created at.

Is there any way to customize this?

We allow the user to perform a selection by clicking like this and do not show the select geometry on the map. In cases where they are on one of these tools the returned results are very misleading.

In other words if the user just clicks expecting to select with a point they will actually be selecting with a polygon generated with a much larger extent but have no way to see this.

Thanks,

I'm assuming there isn't a proper way to do this yet.

As a workaround I added some listeners to see if the user moves the mouse at all. If they don't then I just take the centroid of the geometry that is drawn. Here is the code:

Local variables:

                var mouseMovedAfterDown = false;                 var mouseDownHandler = null;                 var map = null //this is setup elsewhere.

Function to determine if the mouse has moved:

        // some geometries will automatically draw at a set size relative to the current map scale if the mouse isn't moved.         // We don't want this to happen though, to avoid it we add these listeners and get the drawn geometry's center when that occurs.         var watchMouseMoveAfterDown = function () {             var mouseLocation = null;              function mouseDown(event) {                 mouseMovedAfterDown = false;                 console.log("mouseMovedAfterDown = false");                  mouseLocation = { x: event.clientX, y: event.clientY };                 jQuery(document).on("mousemove", mouseMove);                 console.log("mousemove added");                 dojo.disconnect(mouseDownHandler);                 if (!rootScope.$$phase) rootScope.$apply();             }              function mouseMove(event) {                 if (event.clientX !== mouseLocation.x || event.clientY !== mouseLocation.y) {                     mouseMovedAfterDown = true;                     console.log("mouseMovedAfterDown = true");                     jQuery(document).off("mousemove", mouseMove);                     console.log("mousemove removed");                     if (!rootScope.$$phase) rootScope.$apply();                 }             }              if (mouseDownHandler) dojo.disconnect(mouseDownHandler);             mouseDownHandler = dojo.connect(map, "onMouseDown", mouseDown);         };

Before activating the draw tool:

                watchMouseMoveAfterDown();

in the "onDrawEnd" handler:

                    if (!mouseMovedAfterDown && geometry.type !== "point") {                         geometry = geometry.getCentroid();                     }
