Description Resource Path Location Type .... Warning Msg ....

Question

Hi there,
I'm using some code from way back and I'm trying to use it within a newer project.
The original code is as follows:
     import mx.styles.CSSStyleDeclaration;
     import mx.styles.StyleManager;
protected static function classConstruct ():Boolean {
    if (!StyleManager.getStyleDeclaration("Page")){
        var defaultStyles:CSSStyleDeclaration = new CSSStyleDeclaration();
        for (var i:String in DEFAULT_STYLES){
     defaultStyles.setStyle(i, DEFAULT_STYLES[i]);
     StyleManager.setStyleDeclaration("Page", defaultStyles, true);
     return true;
This gives me a couple of Warning !
Description Resource Path Location Type
3608: 'getStyleDeclaration' has been deprecated since 4.0.
Please use 'IStyleManager2.getStyleDeclaration on a style manager instance'.
Page.as line 146 Flex Problem
I have been trying to change it, but I get Error Msg's now !
     import mx.styles.CSSStyleDeclaration;
     import mx.styles.IStyleManager2;
protected static function classConstruct ():Boolean {
    if (!IStyleManager2.getStyleDeclaration("Page")){
        var defaultStyles:CSSStyleDeclaration = new CSSStyleDeclaration();
        for (var i:String in DEFAULT_STYLES){
     defaultStyles.setStyle(i, DEFAULT_STYLES[i]);
     IStyleManager2.setStyleDeclaration("Page", defaultStyles, true);
     return true;
Any help would be very much appriciated. regards aktell2007

Answer 1

Get a style manager instance by calling styleManager on a UIComponent or calling StyleManager.
getStyleManager(moduleFactory);
Each Application/Module has a style manager so using the top-level application will only work correctly if you do not use modules or sub-applications. Otherwise if a module calls code and sets a style into the top-level style manager, the module will be pinned in memory by that reference.
As Alex said, put a defaults.css in your library.swc to set default styles. Look at how it is done in framework.swc and spark.swc.
