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

Hi all, I had not looked well at the resize event. It appears it is only thrown in FF for window resizes. In IE it does work for elements (http://msdn.microsoft.com/en-us/library/ms536959%28VS.85%29.aspx). Maybe there are workarounds like the YUI resize utility: http://developer.yahoo.com/yui/resize/. However, I am not sure if this actually provides the ability to monitor resizes of any element. Within a specific GUI framework, such as Ext-GWT or SmartGWT the panels will throw resize events and then the application developer would be responible for listening to that event and calling updateSize. However, it would be nice if it would work in native GWT.
