Hi Muzak,
Manish and I just had a conversation on flexcoders;
Passing "false" to setStyleDeclaration() in a component's static
initialiser
I can never get the url from gmail but, that is the subject.
Basically do this in your static initializer.
This is what I do with all of my components,
Creation method::
public static function
createSelector(selectorName:String):CSSStyleDeclaration
{
var selector:CSSStyleDeclaration =
StyleManager.getStyleDeclaration(selectorName);
if (!selector)
{
selector = new CSSStyleDeclaration();
StyleManager.setStyleDeclaration(selectorName, selector,
false);
}
return selector;
}
In the custom component class::
private static function initStyles():Boolean
{
var styles:CSSStyleDeclaration =
FSCollectionDefaults.createSelector("TaskListFX");
styles.defaultFactory = function():void
{
this.borderStyle = "solid";
this.offsetBorder = true;
this.paddingBottom = 3;
this.paddingLeft = 3;
this.paddingRight = 3;
this.paddingTop = 3;
this.verticalGap = 6;
}
return true;
}
Creating a default factory does this, instead of using setStyle() you
create the defaults to the defaults.
setStyle() adds the values to the overrides object. Using the
defaultFactory function creates the low level defaults and then you can call
setStyle on the selector and it will override the default factories styles.
I have never had a problem with this technique.
Peace, Mike

You can find more by solving the problem then by 'asking the question'.
