[flexcoders] Passing delegates / function signatures [with Code Sample]

Mon, 17 Oct 2005 05:18:10 -0700

Hi Guys,
I know my syntax is correct because both samples compile but only the first sample calls QueryResult.
The reason i need to pass function pointers i baecause since flex remoteobjects are async i have a function that i may want to handle the results differently based on form data bindings


 This works :
//--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

<mx:Button label="Execute Query" click="ExecuteQuery(RequestParams.requestXML,RequestParams.dataflow,RequestParams.provider,null);"/>

function ExecuteQuery(requestXML:String, dataflowName:String, providerGroup:String)
             {
                mySDK.addEventListener("ExecuteQueryResult", Delegate.create(this, QueryResult));
                mySDK.ExecuteQuery(requestXML, dataflowName, providerGroup);
             }

//--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

But this Does NOT :

    <mx:Button label="Execute Query" click="ExecuteQuery(RequestParams.requestXML,RequestParams.dataflow,RequestParams.provider,null,Delegate.create(this, QueryResult));"/>

function ExecuteQuery(requestXML:String, dataflowName:String, providerGroup:String, callBack:Function)
             {
                mySDK.addEventListener("ExecuteQueryResult", callBack);
                mySDK.ExecuteQuery(requestXML, dataflowName, providerGroup);
             }

//-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

can anyone tell me how to pass function pointers correctly?
