Component Writer's Guide :: Control styles

ControlStyles is a way the IDE uses to know more about your component and specifically, how to handle it, here is a list of valid ones for 1.0 release:

• csRenderAlso=classname,classname Indicates the IDE to render this component and also the components which classnames are on the comma separated list
• csDesignEncoding=string Indicates the encoding to use when rendering the component
• csTopOffset=integer Indicates the IDE a displacement when getting the image of it

A sample on how to use it, for example, to request to render also all SpeedButtons found on the form, so they are available:

        function __construct($aowner=null)
        {
                //Calls inherited constructor
                parent::__construct($aowner);
 
                $this->ControlStyle = "csRenderAlso=SpeedButton";
        }
