Extending the ArcGIS Viewer for Flex "Virtual Campus"

DustinHolt

I'm taking the course "Extending the ArcGIS Viewer for Flex" and I have a problem with a custom widget. In "Step 5: Wire the event handlers" they are asking me to "Create a new instance of FeatureLayer and assign it to the existing myFeatureLayer instance variable". I have attached the instructions and code. It says to create this within the "open handler function", can any one show me where this is?

Dustin,

Not sure if you missed a step some where or what but if you go to the WidgetTemplate does it have an open attribute? and if so does it have the convexHull_openHandler(event)? If it does than try deleting out the convexHull_openHandler(event) from between the double quotes and then then delete the beginning " and retype it. That should bring up a dialog choose "generate open handler" and now you will find the protected function you are looking for.

Dustin,

Sure, when working with widgets the WidgetTemplate has both an open and closed event.

<viewer:WidgetTemplate id="convexHull"
                           width="300" height="300">
                                 open="convexHull_openHandler(event)">

Does that help?

DustinHolt

Not really. The location where they want me to add the code is confusing me. If you look at the code in the tutorial, they want you copy and paste it under:

protected function convexHull_openHandler(event:Event):void
{
// TODO Auto-generated method stub

This "protected function" doesn't exist in my code.

I did miss a step. Fixed it, all makes sense now. Thanks.
