There's a reason for RequiresResize to have an onResize method rather than relying on setSize. One of the goals (expectations? dreams?) of layout panels was that the layout could be done in pure CSS (including animations) and you'd only need to notify widgets when their size has changed (through onResize), something that you know when it happens because the layout is controlled from the outside in (it should only happen the top layout panel is resized, or some panels' inner layout change, or possibly when font sizes or zoom change; there's the case of borders and margins but you're supposed to know what you're doing so you could call onResize or forceLayout then). -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
