We are using a Legend control (data provided by a Chart). When the use clicks
on an item in the legend, we need to capture this event. We are facing the
current problems:

1. The text in the Legend control needs to be underlined. We have set the
textDecoration="underline" as indicated by the API but the text is not
underlined.
2. We want to show a hand cursor when the user hovers on the item. To do this
we have set useHandCursor="true" mouseChildren="false" buttonMode="true"
The problems are (a) If mouseChildren is set to false, we cannot capture the
item click event. If its set to true, the hand cursor is shown on the
background, not the item text.

Please advise.

Could you post exactly what you tried?

I think you'll need to subclass LegendItem to get this behavior.

HTH;

Thanks!

Can you please give me a quick example on how I do that?

I dont want to create Legend items as they are sourced by the chart.

Here's an extended LegendItem I used to make the text wrap. You'd just
override the constructor to set the mouseChildren, etc. properties

package com.magnoliamultimedia.views
{
import flash.display.DisplayObject;

import mx.charts.LegendItem;
import mx.core.UITextField;

public class WrappingLegendItem extends LegendItem
{
public function WrappingLegendItem()
{
super();
}
override protected function createChildren():void{
super.createChildren();
for (var i:int=0;i<numChildren; i++){
var childisplayObject=getChildAt(i);
var txt:UITextField = child as UITextField;
if (!(txt==null)){
txt.wordWrap=true;
txt.invalidateSize();
}
}
}
}
}

It's used like this:

<mx:Legend dataProvider="{subjectAllAttempts}"
direction="horizontal" horizontalAlign="center"
labelPlacement="bottom" verticalAlign="middle"
legendItemClass="com.magnoliamultimedia.views.Wrap pingLegendItem"
/>

Ok, I'll try that. What about the textDecoration property set to underline. It doesn't show the text as underlined. Is this a Flex API bug or am I doing something wrong?

I don't know what you're doing, so I can't speculate about whether it is
wrong or right.

All I am doing is setting textDecoration="underline" - shouldnt the items be
then underlined?

<mx:Legend verticalGap="1" horizontalAlign="left" markerHeight="8"
markerWidth="8"
width="780" dataProvider="{MyDataProvider}"
fontSize="10" id="ChartLegend" textDecoration="underline"
height="70" x="10" y="337"
useHandCursor="true" mouseChildren="false" buttonMode="true">
</mx:Legend>

Try:

<mx:Style>
LegendItem {
textDecoration:underline;
}
</mx:Style>

Thansk Amy, however that does not work too. I have tried almost everything and
cant get the text in the Legend item to be underlined.

Can you please try to add a Legend Control and see if it the
textDecoration="underline" works for you?

Anyone having a similar problem with the Legend control?
