My code:

package com.project.swf
{
    import flash.display.*;
    import flash.text.*;
    import flash.utils.*;
    import fl.controls.*;
    import fl.containers.*;
    import fl.core.UIComponent;
    
    public class Contato extends MovieClip
    {        
        private var textFormat:TextFormat = new TextFormat();
        
        public function Contato()
        {
            _this_init();
        }
        
        private function _this_init():void
        {            
            textFormat = this.tahoma.defaultTextFormat;
            
            combobox.dropdown.setRendererStyle("textFormat", textFormat);
            combobox.textField.setStyle("textFormat", textFormat);
            combobox.setStyle("textFormat", textFormat);
            combobox.textField.setStyle("embedFonts", true);
            combobox.dropdown.setRendererStyle("embedFonts", true);
            
            // Combo Padding
            
            combobox.setStyle("textPadding", 1);
        }
        
        // Getters and Setters
        
        private function get combobox():ComboBox
        {
            return this._form.getChildByName("_combobox") as ComboBox;
        }
        
        private function get tahoma():TextField
        {
            return this._form.getChildByName("_tahoma") as TextField;
        }
        
    }
}
