PROBLEM SUMMARY

You want to use a SWF file with a set of own symbols in order to customize Combobox states.

SOLUTION SUMMARY

Use the upSkin, overSkin, downSkin, and disabledSkin style properties of the ComboBox class to apply custom symbols to any combobox. These attributes can be set directly on a ComboBox instance or as part of a CSS style definition.

EXPLANATION

The first thing to do is create a file in Flash and ComboBoxSkins.swf within it to create 4 symbols of type MovieClip with different states of the ComboBox. These symbols should be named: ComboBox_upSkin, ComboBox_downSkin, ComboBox_overSkin, ComboBox_disabledSkin

 If we want to put the CSS inline style do the following:

<?xml version=”1.0″ encoding=”utf-8″?>

<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml” layout=”absolute”>

 <mx:ComboBox x=”196″ y=”135″ 

 upSkin=”@Embed(source=’ComboBoxSkins.swf’, symbol=’ComboBox_upSkin’)”

 overSkin=”@Embed(source=’ComboBoxSkins.swf’, symbol=’ComboBox_overSkin’)”

 downSkin=”@Embed(source=’ComboBoxSkins.swf’, symbol=’ComboBox_downSkin’)”

 disabledSkin=”@Embed(source=’ComboBoxSkins.swf’, symbol=’ComboBox_disabledSkin’)”>

 <!– PUT HERE THE OPTIONS OF COMBOBOX –>

 </mx:ComboBox>

</mx:Application>
