Re: [Gwt-openlayers-users] Dynamic sizing of map

Hi Andrew, There may not be a native GWT resize event, but I looked up that there is a resize event: http://www.quirksmode.org/dom/events/resize.html This event will be available via JavaScript and therefore can be accessed in GWT with some work. Maybe it is possible to take a look at: http://api.jquery.com/resize/ (it is possible to wrap or port that) This is something a JSNI lib could do (still want to pull of the JSNI helper stuff out of GWT-OL and put it in a separate library)...
