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

There isn't a browser event for the resizing of an element... this is less
than ideal but it does work....
// update the map size every second (only way todo this)
Timer timer = new Timer() {
@Override
public void run() {
mapWidget.getMap().updateSize();
}
};
timer.scheduleRepeating(1000);
If anyone has a better idea, I would love to hear it.
