Re: How get widget width, after it's drawed ?

Try this method that uses ComputedStyle. I couldn't be bothered to optimize it with deferred binding so it does some runtime checks.

static public native String getComputedStyleProperty(Element el, String property) /*-{

        if (window['getComputedStyle']) { // W3C DOM method

    if (property === 'float')

    property = 'cssFloat';

            var value = el.style[property], computed;

            if (!value) {

                computed = el['ownerDocument']['defaultView']['getComputedStyle'](el, null);

                if (computed) { // test computed before touching for safari

                    value = computed[property];

                }

            }

            return value;

        } else if (el['currentStyle']) {

            var value;

            switch(property) {

                case 'opacity' :// IE opacity uses filter

                    value = 100;

                    try { // will error if no DXImageTransform

                        value = el.filters['DXImageTransform.Microsoft.Alpha'].opacity;

                    } catch(e) {

                        try { // make sure its in the document

                            value = el.filters('alpha').opacity;

                        } catch(err) {

                        }

                    }

                    return value / 100;

                case 'float': // fix reserved word

                    property = 'styleFloat'; // fall through

                default:

                    value = el['currentStyle'] ? el['currentStyle'][property] : null;

                    return ( el.style[property] || value );

            }

        }

        return "";

}-*/;
