[flexcoders] Component Life Cycle
Hi Guys, I had a question regarding the component life cycle. I am extending flex charts and adding my custom style to it. But when I load the chart I see the default flex axis being shown and than it would disappear and my styled axis shows up. I am wondering where do I style my axis such that default flex components are not rendered. Currently I am doing my custom styling in initialize() method. Please let me know which component life cycle method show I be doing the styling. Your replies would be appreciated. Thanks Pratik
Re: [flexcoders] Component Life Cycle
I think I understand your question. Try throwing this in your component
(outside of any methods/properties) and tweaking for your needs:
// Default styles
//
private static var classConstructed:Boolean = classConstruct();
/**
* @private
* Creates default styles that can be overridden by the developer.
*/
private static function classConstruct():Boolean {
var styleDeclaration:CSSStyleDeclaration =
StyleManager.getStyleDeclaration('Cursor');
if (!styleDeclaration) {
styleDeclaration = new CSSStyleDeclaration();
}
styleDeclaration.defaultFactory = function():void {
this.color = 0xFF;
}
StyleManager.setStyleDeclaration('Cursor', styleDeclaration,
false);
return true;
}
Note that Cursor is the component's name. This way of setting a default
style personally seems rather unorthodox but it's the only way I've seen
that works. I hope a better/developer-friendly approach is offered in
future versions of Flex.

Re: [flexcoders] component life cycle question
Hi. Im replying to my own post coz Ive worked out something... I should pass the dataProvider fo the datagrid in my component from the main application (or some controller class). I guess this is the recommended way: That is. Supply any data for childcomponents from a main component. Any suggestions or thoughts on this are welcome... Kr. Luke. Luke Vanderfluit wrote: Hi. Ive been reading up on the component life cycle. However the following problem I still cant solve. I have an main application component that gets passed a request parameter (personid) at runtime. (Application.application.parameters.personid) I then have a component called 'sitelist' that builds a datagrid based on a server request involving the personid, so the server request relies on the personid being passed on. In my main app I am able to see the personid parameter on loading, but in the sitelist component personid is null on loading. It seems that the child component renders before the main app and therefore the parameter doesnt exist at the time that the child is created. What is the recommended way of getting a runtime parameter in a subcomponent? I appreciate any help. Kr.
