How can I extend a LinkButton to allow HTML text in Flex?
- by John Isaacks
I am feeding the label to my LinkButton directly from a string I receive from a Google API that puts html to format the label.
I want to extend linkbutton to allow this. I wrote a class myself to allow html text for the label and that aspect of it works but now the background that appears when you hover is way too big. I tried to override measure() to fix this but I didn't have a clue how. Here is the class I wrote:
package com.kranichs.components
{
import mx.controls.LinkButton;
public class HTMLLinkButton extends LinkButton
{
protected var _isHTML:Boolean;
public function HTMLLinkButton()
{
super();
}
[Bindable]
public function set isHTML(value:Boolean):void
{
_isHTML = value;
}
public function get isHTML():Boolean
{
return _isHTML;
}
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(_isHTML)
{
textField.htmlText = label;
}
}
}
}
