RE: [flexcoders] New to Flex - dynamic text in mx:Label?

[Tracy Spratt]

Yes.  An inline renderer creates a sub-component, with its own scope, and it 
does not have direct access to its parent scope.  Use

outerDocument.statusToImage()

 

See this for details:

Would the problem be the manner in which I am invoking it?

 

<mx:DataGridColumn width="90" headerText="Status" dataField="status">

<mx:itemRenderer>

<mx:Component>

<mx:VBox 

width="100%" height="100%" 

horizontalAlign="center" verticalAlign="middle"

> 

<mx:Label text="{statusToImage('abc')}" />

</mx:VBox>

</mx:Component>

</mx:itemRenderer>

</mx:DataGridColumn>

        Hi, Alex.
        
        Tried your example. It works. %)
        
        However, maybe what you need is something like this:
        
            [Bindable]
            protected function get someText() : String {
                return _someText;
            }
            
            protected function set someText(value : String) : void {
                _someText = statusToImage(value);
            }
            
            private var _someText : String;
        
        and:
        
            <mx:Label text="{someText}" /> 
        
        This seems pretty flexible to me.
        
        R.

        Hi there,
        
        Given this function:
        
        <mx:Script> 
        <![CDATA[
        
        private function statusToImage(data:String):String { 
        return "test"; 
        }
        
        ]]>
        </mx:Script>
        
        How precisely can I set it as text-generator for a label? I've tried:
        
        <mx:Label text="{statusToImage('abc')}" />
        
        And Flex Builder writes: "1180: Call to a possibly undefined method
        statusToImage.".
        
        Seems it's right above in the same mxml file though!
        
        Thanks in advance.
        Alex
