How to set a selection in the GWT CellBrowser

Question

somehow I have the feeling that I miss the forest for the trees. I have a CellBrowser filled with categorys and I have a search dialog to find the categorys by name. If I now select a category in the search dialog I also want it to be selected in the CellBrowser.

What I can already do is, find the node in the category tree. I also have the path from the root node to the leaf. I can open the nodes until the selected leaf (getCellBrowser().getRootTreeNode().setChildOpen(i, true). But how do I select the leaf itself? And frankly speaking, is that the right way to do it? (I doubt it somehow)

Greetings Ole

Selecting an Object in the CellWidgets can be done by via the SelectionModel.
Assuming that you have defined a SelectionModel (i.e. SingleSelectionModel) for your CellBrowser/TreeViewModel you can just select a node in a CellBrowser by calling:

selectionModel.setSelected(MyObject, true);

MyObject is the object/type which is displayed as a node in your CellBrowser.
Note you can have different types/objects for each CellBrowser level.
SelectionModel will use either a KeyProvider or the equals function to select the object.
