CHAPTER 11

In this method, the Flash Drawing API is used to draw a rectangle directly into an empty MovieClip

named rectTarget_mc. rectTarget_mc is prepositioned on the stage and serves as the selected color

swatch. The third line of ActionScript

(rectTarget_mc.beginFill(parseInt("0x" + color.substr(1, 6)), 100);)

demonstrates how to convert the color string returned from Fireworks into a hexadecimal value

that Flash can use in its beginFill method. This solid color conversion example is an easy one. The

Gradient panel that I wrote has to convert back and forth between the Fireworks gradient format and

the Flash gradient format constantly throughout its life cycle. After publishing the SWF (press Alt+F+B

or Shift/Cmd+F12) and testing Draw Rect.swf, the ColorPicker now works as expected, launching the

native Fireworks color picker and drawing the selected color in the Flash panel. However, there’s still

one piece missing: the

Add Rect button’s event handler needs to be updated to take advantage of the

selected color. Back to the code:

executeJSF_btn.onRelease = function() {

// Execute the JSF, creating the CreateRectangle function

MMExecute(jsfCode_txt.text);

// Calculate the CornerRadius value

var cornerRadius:Number = nsCornerRadius.value / 100;

// Call CreateRectangle

MMExecute("CreateRectangle(" + nsX.value + "," + nsY.value ➥

+ "," + nsWidth.value + "," + nsHeight.value + "," ➥

+ cornerRadius.toString() + ", '" + currentColor + "');");

}

Notice that the hard- coded #FF0000 color string has been replaced with the currentColor variable

in the second MMExecute() call. After publishing again, you can select a color, click

Add Rect, and the

selected color is applied as expected!

This is just one example of many cases where Fireworks and Flash values vary to a certain extent. You

have to know the differences between ActionScript requirements and the Fireworks object model and

convert these values into something that can be used.

Streamlining your workflow with the Fireworks

developer toolbox

So far we’ve shown you how to execute JSF inline via MMExecute() and by including the JSF in a

TextBlock on the design surface. You’ll never get away from the first method completely, but you

should not have to rely on it exclusively. The TextBlock method gives you a way to import your JSF

without having to escape all of your JSF. This is great for small chunks of JSF but introduces another

manual step that can result in errors. Having to copy and paste all of your JSF code from a text editor

to the design surface in Flash becomes laborious, and it’s one of those steps that can drive you crazy.

Fortunately, there’s another approach that can streamline your workflow even further, and it doesn’t

change the workflow proposed at the beginning of this chapter. It actually continues to enable it for
