measuredWidth

屬性

measuredWidth:Number [唯讀]

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

The measured width of this object. This should be overridden by subclasses to return the preferred width for the skin.

實作

nestLevel

屬性

nestLevel:int

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Depth of this object in the containment hierarchy. This number is used by the measurement and layout code. The value is 0 if this component is not on the DisplayList.

實作
public function get nestLevel():int
public function set nestLevel(value:int):void

processedDescriptors

屬性

processedDescriptors:Boolean

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Set to true after immediate or deferred child creation, depending on which one happens. For a Container object, it is set to true at the end of the createComponentsFromDescriptors() method, meaning after the Container object creates its children from its child descriptors.

For example, if an Accordion container uses deferred instantiation, the processedDescriptors property for the second pane of the Accordion container does not become true until after the user navigates to that pane and the pane creates its children. But, if the Accordion had set the creationPolicy property to "all", the processedDescriptors property for its second pane is set to true during application startup.

For classes that are not containers, which do not have descriptors, it is set to true after the createChildren() method creates any internal component children.

實作
public function get processedDescriptors():Boolean
public function set processedDescriptors(value:Boolean):void

drawRoundRect

()

方法

 protected function drawRoundRect(x:Number, y:Number, width:Number, height:Number, cornerRadius:Object = null, color:Object = null, alpha:Object = null, gradientMatrix:Matrix = null, gradientType:String = "linear", gradientRatios:Array = null, hole:Object = null):void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Programatically draws a rectangle into this skin's Graphics object.

The rectangle can have rounded corners. Its edges are stroked with the current line style of the Graphics object. It can have a solid color fill, a gradient fill, or no fill. A solid fill can have an alpha transparency. A gradient fill can be linear or radial. You can specify up to 15 colors and alpha values at specified points along the gradient, and you can specify a rotation angle or transformation matrix for the gradient. Finally, the rectangle can have a rounded rectangular hole carved out of it.

This versatile rectangle-drawing routine is used by many skins. It calls the drawRect() or drawRoundRect() methods (in the flash.display.Graphics class) to draw into this skin's Graphics object.

參數

	`x:Number` — Horizontal position of upper-left corner of rectangle within this skin.

	`y:Number` — Vertical position of upper-left corner of rectangle within this skin.

	`width:Number` — Width of rectangle, in pixels.

	`height:Number` — Height of rectangle, in pixels.

	`cornerRadius:Object` (default = `null`) — Corner radius/radii of rectangle. Can be `null`, a Number, or an Object. If it is `null`, it specifies that the corners should be square rather than rounded. If it is a Number, it specifies the same radius, in pixels, for all four corners. If it is an Object, it should have properties named `tl`, `tr`, `bl`, and `br`, whose values are Numbers specifying the radius, in pixels, for the top left, top right, bottom left, and bottom right corners. For example, you can pass a plain Object such as `{ tl: 5, tr: 5, bl: 0, br: 0 }`. The default value is null (square corners).

	`color:Object` (default = `null`) — The RGB color(s) for the fill. Can be `null`, a uint, or an Array. If it is `null`, the rectangle not filled. If it is a uint, it specifies an RGB fill color. For example, pass `0xFF0000` to fill with red. If it is an Array, it should contain uints specifying the gradient colors. For example, pass `[ 0xFF0000, 0xFFFF00, 0x0000FF ]` to fill with a red-to-yellow-to-blue gradient. You can specify up to 15 colors in the gradient. The default value is null (no fill).

	`alpha:Object` (default = `null`) — Alpha value(s) for the fill. Can be null, a Number, or an Array. This argument is ignored if `color` is null. If `color` is a uint specifying an RGB fill color, then `alpha` should be a Number specifying the transparency of the fill, where 0.0 is completely transparent and 1.0 is completely opaque. You can also pass null instead of 1.0 in this case to specify complete opaqueness. If `color` is an Array specifying gradient colors, then `alpha` should be an Array of Numbers, of the same length, that specifies the corresponding alpha values for the gradient. In this case, the default value is `null` (completely opaque).

	`gradientMatrix:Matrix` (default = `null`) — Matrix object used for the gradient fill. The utility methods `horizontalGradientMatrix()`, `verticalGradientMatrix()`, and `rotatedGradientMatrix()` can be used to create the value for this parameter.

	`gradientType:String` (default = "`linear`") — Type of gradient fill. The possible values are `GradientType.LINEAR` or `GradientType.RADIAL`. (The GradientType class is in the package flash.display.)

	`gradientRatios:Array` (default = `null`) — (optional default [0,255]) Specifies the distribution of colors. The number of entries must match the number of colors defined in the `color` parameter. Each value defines the percentage of the width where the color is sampled at 100%. The value 0 represents the left-hand position in the gradient box, and 255 represents the right-hand position in the gradient box.

	`hole:Object` (default = `null`) — (optional) A rounded rectangular hole that should be carved out of the middle of the otherwise solid rounded rectangle { x: #, y: #, w: #, h: #, r: # or { br: #, bl: #, tl: #, tr: # } }

getStyle

()

方法

public function getStyle(styleProp:String):*

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Returns the value of the specified style property.

參數

styleProp:String — Name of the style property.

傳回值

* — The style value. This can be any type of object that style properties can be, such as int, Number, String, etc.

horizontalGradientMatrix

()

方法

protected function horizontalGradientMatrix(x:Number, y:Number, width:Number, height:Number):Matrix

語言版本:

ActionScript 3.0

產品版本:

Utility function to create a horizontal gradient matrix.

參數

	`x:Number` — The left edge of the gradient.

	`y:Number` — The top edge of the gradient.

	`width:Number` — The width of the gradient.

	`height:Number` — The height of the gradient.

傳回值

Matrix — The horizontal gradient matrix. This is a temporary object that should only be used for a single subsequent call to the drawRoundRect() method.

invalidateDisplayList

()

方法

public function invalidateDisplayList():void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Marks a component so that its updateDisplayList() method gets called during a later screen update.

Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the width and height, it would be wasteful to update the component immediately after you change the width and then update again with the new height. It is more efficient to change both properties and then render the component with its new size once.

Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

invalidateProperties

()

方法

public function invalidateProperties():void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Calling this method results in a call to the component's validateProperties() method before the display list is rendered.

For components that extend UIComponent, this implies that commitProperties() is called.

invalidateSize

()

方法

public function invalidateSize():void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Calling this method results in a call to the component's validateSize() method before the display list is rendered.

For components that extend UIComponent, this implies that measure() is called, unless the component has both explicitWidth and explicitHeight set.

參數

styleProp:String — The name of the style property that changed, or null if all styles have changed.

updateDisplayList

()

方法

protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Programmatically draws the graphics for this skin.
