http://code.google.com/intl/fr-FR/webtoolkit/doc/latest/DevGuideUiPanels.html#Recipes Search for "Using a LayoutPanel without RootLayoutPanel", then look for "RequiresResize and ProvidesResize", which says: """The purpose of these two interfaces is to form an unbroken hierarchy between all widgets that implement RequiresResize and the RootLayoutPanel, which listens for any changes (such as the browser window resizing) that could affect the size of widgets in the hierarchy.""" => keywords: "unbroken hierarchy" In your case, maybe you could just implement RequiresResize on your Application composite to delegate to indexPanel.onResize(), and give both your widgets a size of 100%. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
