120 Styles and Skinning

Using the StyleManager

When you use the StyleManager to apply styles to entire classes, you must now access the class

with the

getStyleDeclaration() method. For example:

Flex 1.x:

StyleManager.styles.Button.setStyle("color","red");

Flex 2:

StyleManager.getStyleDeclaration("Button").setStyle("color","red");

You can no longer set or get styles as properties of a component or class. You now use

setStyle() and getStyle(). This also applies to using StyleManager. While accessing styles

this way was discouraged in Flex 1.5, it was not prohibited until now.

Flex 1.x:

var c = myButton.color;

StyleManager.styles.TextArea.color = "red";

Flex 2:

var c:Number = myButton.getStyle("color");

StyleManager.getStyleDeclaration("TextArea").setStyle("color","red");

In addition, you can no longer create a CSSStyleDeclaration object and then apply it to a type

of control, as the following example shows:

public var styleObj:CSSStyleDeclaration = new CSSStyleDeclaration();

styleObj.setStyle("color","red");

styleObj.setStyle("fontFamily","Tahoma");

StyleManager.styles.Accordion = styleObj;

You must now use the setStyle() method; for example:

StyleManager.getStyleDeclaration("Accordion").setStyle("color","red");

StyleManager.getStyleDeclaration("Accordion").setStyle("fontFamily","Tahoma

");

You can also use the StyleManager.setStyleDeclaration() method.

The

getNonInheritingStyle() and getInheritingStyle() methods were removed. You

can now use the

getStyle() method instead.
