selectors | property |
selectors:Array [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns an Array of all the CSS selectors that are registered with the StyleManager.
You can pass items in this Array to the getStyleDeclaration() method to get the corresponding CSSStyleDeclaration object.
Class selectors are prepended with a period.
Implementation
public static function get selectors():ArrayclearStyleDeclaration | () | method |
public static function clearStyleDeclaration(selector:String, update:Boolean):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Clears the CSSStyleDeclaration object that stores the rules for the specified CSS selector.
If the specified selector is a class selector (for example, ".bigMargins" or ".myStyle"),
you must be sure to start the
selector property with a period (.).
If the specified selector is a type selector (for example, "Button"), do not start the
selector property with a period.
The global selector is similar to a type selector
and does not start with a period.
Parameters
selector:String — The name of the CSS selector to clear.
| |
update:Boolean — Set to true to force an immediate update of the styles.
Set to false to avoid an immediate update of the styles in the application.
For more information about this method, see the description in the setStyleDeclaration()
method.

getColorName | () | method |
public static function getColorName(colorName:Object):uint| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns the numeric RGB color value that corresponds to the
specified color string.
The color string can be either a case-insensitive color name
such as "red", "Blue", or
"haloGreen", a hexadecimal value such as 0xFF0000, or a #-hexadecimal String
such as "#FF0000".
This method returns a uint, such as 4521830, that represents a color. You can convert
this uint to a hexadecimal value by passing the numeric base (in this case, 16), to
the uint class's toString() method, as the following example shows:
import mx.styles.StyleManager;
private function getNewColorName():void {
StyleManager.registerColorName("soylentGreen",0x44FF66);
trace(StyleManager.getColorName("soylentGreen").toString(16));
}
Parameters
colorName:Object — The color name.
|
uint — Returns a uint that represents the color value or NOT_A_COLOR
if the value of the colorName property is not an alias for a color.
|
getColorNames | () | method |
public static function getColorNames(colors:Array):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Converts each element of the colors Array from a color name
to a numeric RGB color value.
Each color String can be either a case-insensitive color name
such as "red", "Blue", or
"haloGreen", a hexadecimal value such as 0xFF0000, or a #-hexadecimal String
such as "#FF0000"..
Parameters
colors:Array — An Array of color names.

getStyleDeclaration | () | method |
public static function getStyleDeclaration(selector:String):CSSStyleDeclaration| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Gets the CSSStyleDeclaration object that stores the rules for the specified CSS selector.
If the selector parameter starts with a period (.),
the returned CSSStyleDeclaration is a class selector and applies only to those instances
whose styleName property specifies that selector
(not including the period).
For example, the class selector ".bigMargins"
applies to any UIComponent whose styleName
is "bigMargins".
If the selector parameter does not start with a period,
the returned CSSStyleDeclaration is a type selector and applies to all instances
of that type.
For example, the type selector "Button"
applies to all instances of Button and its subclasses.
The global selector is similar to a type selector
and does not start with a period.
Parameters
selector:String — The name of the CSS selector.
|
CSSStyleDeclaration — The style declaration whose name matches the selector property.

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Tests to see if this style affects the component's parent container in such a way as to require that the parent container redraws itself when this style changes.
When one of these styles is set with setStyle(),
the invalidateDisplayList() method is auomatically called on the component's
parent container to make it redraw and/or relayout its children.
Parameters
styleName:String — The name of the style to test.
|
Boolean — Returns true if the specified style is one
which may affect the appearance or layout of the component's

parent container to make its measured size get recalculated
later.

styleName:String — The name of the style to test.
|
Boolean — Returns true if the specified style is one
which may affect the measured size of the component's

|
Boolean — Returns true if the specified style is one
which may affect the measured size of the component.
|
isValidStyleValue | () | method |
public static function isValidStyleValue(value:*):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |

trace(StyleManager.isValidStyleValue(myButton.getStyle("color")).toString());
This can be useful because some styles can be set to values
such as 0, NaN,
the empty String (""), or null, which can
cause an if (value) test to fail.
Parameters
value:* — The style property to test.
|
Boolean — If you pass the value returned by a getStyle() method call
to this method, it returns true if the style
was set and false if it was not set.
