How to align label text to the left in Spark Button (no "textAlign" style)?

Question

Hi all,
"textAlign" style is excluded for Spark Button, and probably for a good reason.
[Exclude(name="textAlign", kind="style")]
  If I want to align Spark Button text label to the left, should I create custom skin to accomplish that?
Something e.g:
<?xml version="1.0" encoding="utf-8"?>
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx"
        minWidth="21" minHeight="21"
        alpha.disabled="0.5">
<s:Label
        id="labelDisplay"       
        textAlign="left"               
        left="2" right="2" top="2" bottom="2"/>
</s:Skin>

Answer 1

    Right, I though about this approach vith setStyle too, but this is not that convenient.
    I looked into source code and find out that spark.components.Button class adds to the spark.components.supportClasses.ButtonBase only one public property "emphasized".
  Because I do not need this property in my project, I've extended my custom LinkButton component from ButtonBase to allow setting "textAlign" style in MXML for this component.
import spark.components.supportClasses.ButtonBase;
public class LinkButton extends ButtonBase {
   Also,  inside custom Skin from my Button component I do not set explicitly "textAlign" style value to the button label, I let button label to inherit style value specified in MXML for the style textAlign of my ListButton component.
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        minWidth="21" minHeight="21"
        alpha.disabled="0.5">       
    <fx:Metadata>
        [HostComponent("component.LinkButton")]
    </fx:Metadata>   
<s:Label
        id="labelDisplay"
        textDecoration="underline"
        maxDisplayedLines="1"
        verticalAlign="middle"
        color="{getStyle('color')}"
        color.over="{getStyle('textRollOverColor')}"       
        color.down="{getStyle('textSelectedColor')}"       
        left="10" right="10" top="2" bottom="2"/>
</s:Skin>
