hi! I'd like to make my CellTree use checkboxes in a way that checking a parent node should check all its children and unchecking it should uncheck all of them. Respectively checking the last unchecked children of a node should make it checked and so on. And I'd like to display a "third state" as well that would represent that the node's children are mixed.
My first approach was writing a "TriStateSelectionEventManager extends DefaultSelectionEventManager" and overriding doMultiSelection).. However I saw that the data I need to do the trick is hidden by the HasData<> interface I get as a parameter, I can only browse it when debugging. The main problem was that I could not cast the HasData<> to its implementation class as it was invisible for outside: CellTreeNodeView.NodeCellList<> nodeCellList = (CellTreeNodeView.NodeCellList<>) display; I'm not sure what to do now and thought that someone could give me a hint here.. :-) br, jabal -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
