Optimizing component styles and performance When using ActionScript 2.0, one of the most processor-intensive calls in a component framework is the setStyle call. The setStyle call executes efficiently, but the call is intensive because of the way it is implemented. The setStyle call is not always necessary in all applications, but if you use it, consider its performance effect. To enhance performance, you can change styles before they are loaded, calculated, and applied to the objects in your SWF file. If you can change styles before the styles are loaded and calculated, you do not have to call setStyle. To improve performance when using styles, set properties on each object as objects are instantiated. When you dynamically attach instances to the Stage, set properties in initObj in the call that you make to createClassObject(), as the following ActionScript shows: createClassObject(ComponentClass, "myInstance", 0, {styleName:"myStyle", color:0x99CCFF}); For instances that you place directly on the Stage, you can use onClipEvent() for each instance, or you can use subclasses (recommended). For information on subclasses, see About writing a subclass in Learning ActionScript 2.0 in Adobe Flash. If you must restyle your components, you can improve efficiency in your application by using the Loader component. To implement several styles in different components, place each component in its own SWF file. If you change styles on the Loader component and reload the SWF file, the components in the SWF file are recreated. When the component is recreated, the cache of styles is emptied, and the style for the component is reset and referenced again. Note: To apply a single style to all instances of a component in your SWF file, change the style globally using _global.styles.ComponentName. Using runtime shared libraries You can sometimes improve download time by using runtime shared libraries. These libraries are usually necessary for larger applications or when numerous applications on a site use the same components or symbols. By externalizing the common assets of your SWF files, you do not download classes repeatedly. The first SWF file that uses a shared library has a longer download time, because both the SWF file and the library load. The library caches on the user's computer, and then all the subsequent SWF files use the library. This process can greatly improve download time for some larger applications.

Optimizing component styles and performance

When using ActionScript 2.0, one of the most processor-intensive calls in a component framework is the

setStyle

call. The

setStyle

call executes efficiently, but the call is intensive because of the way it is implemented. The

setStyle

call is not always necessary in all applications, but if you use it, consider its performance effect.

To enhance performance, you can change styles before they are loaded, calculated, and applied to the objects in your

SWF file. If you can change styles before the styles are loaded and calculated, you do not have to call

setStyle

To improve performance when using styles, set properties on each object as objects are instantiated. When you

dynamically attach instances to the Stage, set properties in

initObj

in the call that you make to

createClas-

sObject()

, as the following ActionScript shows:

createClassObject(ComponentClass, "myInstance", 0, {styleName:"myStyle", color:0x99CCFF});

For instances that you place directly on the Stage, you can use

onClipEvent()

for each instance, or you can use

subclasses (recommended). For information on subclasses, see About writing a subclass in

Learning ActionScript 2.0

in Adobe Flash

If you must restyle your components, you can improve efficiency in your application by using the Loader component.

To implement several styles in different components, place each component in its own SWF file. If you change styles

on the Loader component and reload the SWF file, the components in the SWF file are recreated. When the

component is recreated, the cache of styles is emptied, and the style for the component is reset and referenced again.

Note:

To apply a single style to all instances of a component in your SWF file, change the style globally using

_global.styles.ComponentName

Using runtime shared libraries

You can sometimes improve download time by using runtime shared libraries. These libraries are usually necessary

for larger applications or when numerous applications on a site use the same components or symbols. By external-

izing the common assets of your SWF files, you do not download classes repeatedly. The first SWF file that uses a

shared library has a longer download time, because both the SWF file and the library load. The library caches on the

user’s computer, and then all the subsequent SWF files use the library. This process can greatly improve download

time for some larger applications.
