SplitLayoutPanel is a DockLayoutPanel and a DockLayoutPanel requirement is that the center layer is added last. Once the center layer is added you can not add anything else. Thats because the center panel takes the remaining space and thus the panel needs to know what is already inside that panel to calculate the remaining space.
So using stock GWT classes there is no way to change that behavior. You would need to implement it yourself. Your best bet is probably writing a custom composite that is backed by a SplitLayoutPanel and provides @UiChild methods for north/east/south/center. These methods just store the widgets you add, and in Composite.onLoad() you would build the SplitLayoutPanel based on the added panels. That way the @UiChild methods can be called in any order and in onLoad() you can still build the SplitLayoutPanel with the center panel added last to satisfy DockLayoutPanel requirements. http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/uibinder/client/UiChild.html As an alternative try to refactor your code so that you dont need to access the center panel inside the constructor of the north panel. You could add a ui:field to the north and center panel and in your UiBinder's Java file "connect" both panels *after* binder.createAndBindUi(this) is called. With your current constructor approach you are trying to "connect" both panels *during the execution* of binder.createAndBindUi(this). -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
