processedDescriptors

egenskap

processedDescriptors:Boolean

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

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.

Produktversion:

Körningsmiljöversioner:

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.

Parametrar

	`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: # } }

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

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

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

Returnerar

invalidateDisplayList

()

metod

public function invalidateDisplayList():void

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

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

()

metod

public function invalidateProperties():void

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

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

()

metod

public function invalidateSize():void

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

Flash Player 9, AIR 1.1
