EXTENDING FIREWORKS: DEVELOPING AN EFFECTIVE WORKFLOW USING JAVASCRIPT AND FLASH

Learning the Fireworks object model

This chapter has primarily concerned itself with defining an effective workflow for developing Fireworks

panels. We’ve shown you how to do this in both ActionScript 2 and 3, using both Flash and Flex. Along the

way, we’ve used certain Fireworks methods and handled Fireworks events that you probably didn’t even

know existed. You may have wondered how we knew that calling fw.popupColorPickerOverMouse()

in JSF would launch the color picker or how calling fw.selection[0] would give us a handle to the

first selected object. We learned our way around the Fireworks object model using the following

resources and methods:

The Extending Fireworks documentation

The History panel method—demonstrated at the beginning of this chapter

The FWAPI_Inspector panel

Online samples, tutorials, and articles

The Extending Fireworks documentation

The Extending Fireworks documentation is available online and can be found by selecting Help ➤

Fireworks Help

from the main menu (or directly via http://help.adobe.com/en_US/Fireworks/10.0_

Using/). Select

Extending Adobe Fireworks CS4 from the main menu on the left. This documenta-

tion covers all of the methods, events, objects, and properties available to you as a Fireworks panel

author.

The History panel method

The History panel method introduced at the beginning of this chapter is a fast way to come up to

speed with the methods that Fireworks is calling as you use the tool. You simply perform steps within

Fireworks that you want to know how to achieve via JSF, and then select the steps you just performed

in the

History panel (Window ➤ History). With the steps of interest selected, click the Copy button

to copy the JSF directly to your clipboard. You can then paste the JSF into your authoring tool and

review the code. Learn more about the methods used by looking them up in the Extending Fireworks

documentation.

The FWAPI_Inspector panel

Learning to navigate the Fireworks object model is a fundamental step in Fireworks panel develop-

ment. Often, navigating the Extending Fireworks documentation can be confusing. Fortunately, Aaron

Beall has written a panel that displays the property tree of the currently selected element on the stage

(see Figure 11-18). You can see the values for each property and even edit the properties that aren’t

read- only. Using this panel, you can learn the hierarchy of Fireworks objects and properties and pre-

dictably code against selected objects.
