EXTENDING FIREWORKS: DEVELOPING AN EFFECTIVE WORKFLOW USING JAVASCRIPT AND FLASH

Figure 11‑8. ColorPicker MovieClip added

to the stage

With the MovieClip in place on the stage, add an event handler for its onRelease event and call

fw.popupColorPickerOverMouse() via MMExecute(). MMExecute() will return a color value in the

#RRGGBBAA format that can then be passed to the SetColor method defined on ColorPicker_mc.

Following is the ActionScript event handler for ColorPicker_mc.onRelease:

var currentColor:String = "#FF0000";

colorPicker_mc.onRelease = function()

{

currentColor = MMExecute("fw.popupColorPickerOverMouse('" + ➥

currentColor + "',false,false);");

colorPicker_mc.SetColor(currentColor);

}

The popupColorPickerOverMouse method accepts three parameters: initialColor, allowTransparent,

and forceWeb216. The resulting value is stored in the variable currentColor and passed directly to the

SetColor method of ColorPicker_mc. The following code demonstrates how the SetColor method

works with the Fireworks- returned color value. Like many values returned from Fireworks (or Flash

values going to Fireworks), the value has to be massaged into a format that makes sense to Flash.

function SetColor(color:String)

{

rectTarget_mc.clear();

rectTarget_mc.moveTo(0,0);

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

rectTarget_mc.lineTo(22,0);

rectTarget_mc.lineTo(22,22);

rectTarget_mc.lineTo(0,22);

rectTarget_mc.lineTo(0,0);

rectTarget_mc.endFill();

}
