Either your custom widget extends ResizeComposite<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/ResizeComposite.html> or implements RequiresResize and ProvidesResize interfaces. This will ensure that the onResize event is propagated to your LayoutPanel.
You have to make sure that you put your widget in a ResizeLayoutPanel or in a Panel which implements ProvidesResize and make sure that there is a unbroken chain of ProvesResize/RequiresResize panels up to the RootLayoutPane. Whenever you resize your browser LayoutPanel will resize accordingly. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
