get computed font size of GWT Label

I'd like to be able to access the font size of a GWT Label. I've tried:

String fontSize = label.getElement().getStyle().getFontSize()

but this seems to only be for font sizes that have been programatically set (and not font sizes that are decided by CSS rules). Any ideas?

Thanks,

~Owen

If it is the computed size you are looking for, GWT does not provide it out of the box, but you should be able to use a simple JSNI to retrieve it. Something like:

public static native String getComputedStyleProperty(Element element, String property)  /*-{
  if ($doc.defaultView && $doc.defaultView.getComputedStyle) {
    return $doc.defaultView.getComputedStyle(element, null).getPropertyValue(property);
  }
  return "";
}-*/;

Untested but should get you started. Do note that, the property should be camelCase and, for IE < 9, you should also check for currentStyle. Also a fallback based on element's style property should be returned, instead the empty string. See also Get computed font size for DOM element in JS.

No, getFontSize() returns CSS property only.

Give a try like below:

   String fontsize= DOM.getStyleAttribute(label.getElement(), "font-size");
