Question

how 我感到,我把森林丢给树木。我有一个小组Browser填满了类别,我有一个搜索辩词,以便按姓名找到这些类别。如果我现在选择搜索方言中的一个类别,我也想将其选入单元Browser。

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

Answer 1

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.
