gwt - Treepanel masking -

-

how can mask tree panel until loader loads data server??(at initial loading)

the simplest thing call setvisible(false) on treepanel when first create , make visible in rpc callback.

a more visually elegant approach use setenabled(false) combined css style changes widget more neutral appearance indicate "there data here, can't use yet". setting background light grey color, or perhaps turning down opacity of panel.
