Re: [Gwt-openlayers-users] OL-GWT, SmartGWT and rescale problems

[Edwin C. <com...@gm...>]

Hi Piotr,

Have you tried initiating the MapWidget like this:

mapWidget = new MapWidget("100%", "100%", mapOptions);

I haven't checked the SmartGWT forums, but I'd be happy to know if a
SmartGWT user has a fix for this particular problem. When you use
SmartGWT then SmartGWT will be in charge of resizing, as not all
browsers throw resize events for div's. For GWT-OL it is better not to
know about SmartGWT's resizing, but to get told the new size upon a
SmartGWT event that triggers a resize.

Greetings,
Edwin
