62 Using Metadata Tags in Custom Components
The following example shows the definition of the textSelectedColor style property:
[Style(name="textSelectedColor",type="Number",format="Color",inherit="yes")]
The next example shows the definition of the verticalAlign style property:
[Style(name="verticalAlign", type="String",
enumeration="bottom,middle,top", inherit="no")]
For more information on the [Style] metadata tag, see Chapter 11, “Creating Custom Style
Properties,” on page 183.
arrayType
String If type is Array, arrayType specifies the data type of the Array
elements. If the data type is not an ActionScript type such as
Number or Date, use a qualified class name in the form
packageName.className.
format
String Specifies the units of the property. For example, if you specify type
as
“Number”, you might specify format="Length" if the style defines a
length measured in pixels. Or, if you specify
type="uint", you might
set
format="Color" if the style defines an RGB color.
enumeration
String Specifies an enumerated list of possible values for the style property.
inherit
String Specifies whether the property is inheriting. Valid values are yes and
no. This property refers to CSS inheritance, not object-oriented
inheritance. All subclasses automatically use object-oriented
inheritance to inherit the style property definitions of their
superclasses.
Some style properties are inherited using CSS inheritance. If you set
an inheritable style property on a parent container, its children inherit
that style property. For example, if you define
fontFamily as Times
for a Panel container, all children of that container will also use Times
for
fontFamily, unless they override that property.
If you set a noninheritable style, such as
textDecoration, on a parent
container, only the parent container and not its children use that
style. For more information on inheritable style properties, see
“About style inheritance” in Flex 2 Developer’s Guide.
