Problem with resize flex viewer template

WuYang

Greetings,

In my flex viewer, I need to change the template size at runtime. Have found the previous thread but cannot ask question there.

I refer to the following link:

http://forums.esri.com/Thread.asp?c=158&f=2421&t=279252

I follow the steps advised by Robert as follows:

(1) added the line in IWidgetTemplate.as

function setResize(value1:Number, value2:Number):void;

(2) added the following code in the WidgetTemplate.as

public function setResize(nHeight:Number, nWidth:Number):void
{
this.height  = nHeight;
wCanvas.height = nHeight;     
this.width = nWidth;
wCanvas.width = nWidth - 40;
}

But I got the error:

access of undefined property wCanvas.

(3) add the following in mx:State in the mxml which I want to resize the template.

<mx:SetProperty target="{wCanvas}" name="height" value="{height}"/>

<mx:SetProperty target="{wCanvas}" name="width" value="{width - 40}"/>

But wherever I put the mx:state, It always return me:

<mx:state> is not allowed here.

I am not sure whether step (3) is correct, and where should I define wCanvas? or should I use wTemplate instead of wCanvas?

Or is it because the version is different (I use version 3.6).

Any idea? advice is appreciated.

Wu,

  I dynamically change the size of my widgets at runtime using this code:

wTemplate.widgetWidth = wTemplate.width = 530;
wTemplate.widgetHeight = wTemplate.height = 335;
