How can I access the checkbox of each Ode of a JTree?
TreePath[] checkedPaths = checkTreeManager.getSelectionModel().getSelectionPaths();
The previous code returns me all the selected paths. When I return to mine JTree after losing focus, I would like these paths to be selected.
I tried using the following command:
jTree1.addSelectionPaths(checkedPaths);
The point is that selects me the line of the nodes selected and does not check me in the associated checkbox as you would like.
Does anyone know how I can fix this?
In the second command, when adding selections, the checkedPaths object is the same as the first command?

Yes, it’s the same!

Well, you need to select from the Selectionmodel and not direct from jTree1. So:
checkTreeManager.getSelectionModel().addSelectionPaths(checkedPaths);– Franchesco
And I place this command after jtree is fed back?

This command you replace with your second command in the question...

If you put as you told me, do not select as I want, maybe by my mistake here in the code, however if you do: 'checkTreeManager.getSelectionModel(). addSelectionPath(jTree1.getPathForRow(4));' selects it right as I want, so I’ll save the indexes of the selected paths and then do it :D

@Earendul already got to select but I’m having trouble selecting the Child nodes. Ex: root->A->A1, if the path is this and I select A1, it is not selected :s

If A has only this child, then it will be selected A. But if A has no siblings, it will select only root. That is, when all the children of a node are selected, it returns only their father. For example, if it returns A as the last selected node, it means that all children of A are also selected.

Right and in the selection mode this happens, the question is that I have: Root->A->A1, A2 (where A1 and A2 are children of A) if my selection is A1, it does not select me this path. I think I know where my problem is that I’m going through jtree like this: for(int i = 0; i<jtree.getRowCount();i++) and supposedly this rowCount I don’t think it counts A1 and A2, it only counts Root-> A , B , C
