snapping in flex

NigelDsouza

Hi,

I want to add snapping functionality to my application. The arcgis api for flex states that the snapping mode default is on demand. I have debugged the code and checked, the editor contains all the featurelayers needed to work with. However whenever I try snapping while adding or updating a feature they don't snap. I tried using the default edit widget in the flex viewer but snapping doesn't seem to be working there as well. Can anyone suggest somet

Nigel,

I believe by default snapping is available.  You can expressly set snapping parameters for the edit tool or draw tool.  Here is an excerpt from the API reference:

snapMode

property

snapMode:String

Since :

ArcGIS API for Flex 2.5

Specifies whether snapping is off, always on or enabled by pressing the Ctrl key.

The default value is SNAP_MODE_ON_DEMAND.

This property can be used as the source for data binding.

Implementation

    public function get snapMode():String

    public function set snapMode(value:String):void

I put together a measure widget that is a variation of the draw tool.  It also has snapping capability.  You can view it here:

Yakima CityFlex Viewer - measure widget

Here is a code snippet from my measure widget setting the draw tool snapping parameters:

<esri:DrawTool id="measureDrawTool" map="{map}"

   snapDistance="20" snapMode="onDemand" snapOption="vertex"

   showDrawTips="{showDrawingTips}"

   drawEnd="map_drawEndHandler(event)"

   graphicsLayer="{graphicsLayer}"

   lineSymbol="{lineSymbol}"

   fillSymbol="{fillSymbol}" />

I hope this helps you!

Regards,

Tom
