You can create a CheckBoxTree just as you create a normal JTree. For example:

CheckBoxTree tree = new CheckBoxTree(new Object[]{"one", "two", "three"});

or

CheckBoxTree tree = new CheckBoxTree(new DefaultTreeModel());

The CheckBoxTreeSelectionModel is retrieved and assigned respectively with:

public CheckBoxTreeSelectionModel getCheckBoxSelectionModel();

public void setCheckBoxSelectionModel(CheckBoxTreeSelectionModel checkSelectionModel);

You can also change the gap that exists between the checkbox and the node's value with the method:

public void setCheckBoxGap(int checkBoxGap);

CheckBoxTree can also be assigned to a TreeTable:

CheckBoxTree tree = new CheckBoxTree();

TreeTable table = new TreeTable();

table.getTreeTableModelAdapter().setTree(tree);
