我想我找到了解决方案

您将需要扩展JTree和DefaultTreeSelectionModel.

JTree相关方法：

/

/

/// Implement selection using "adding" only logic. //

/

/

@Override

public void setSelectionPath(TreePath path) {

System.out.println("MLDebugJTree: setSelectionPath(" + path + ")");

addSelectionPath(path);

return;

//super.setSelectionPath(path);

}

@Override

public void setSelectionPaths(TreePath[] paths) {

System.out.println("MLDebugJTree: setSelectionPaths(" + paths + ")");

addSelectionPaths(paths);

return;

}

@Override

public void setSelectionRow(int row) {

System.out.println("MLDebugJTree: setSelectionRow(" + row + ")");

addSelectionRow(row);

return;

//super.setSelectionRow(row);

}

@Override

public void setSelectionRows(int[] rows) {

System.out.println("MLDebugJTree: setSelectionRows(" + rows + ")");

addSelectionRows(rows);

return;

//super.setSelectionRows(rows);

}

DefaultSelectionModel相关方法：

package com.ml.tree2.model.impl;

import javax.swing.tree.DefaultTreeSelectionModel;

import javax.swing.tree.TreePath;

public class MLTreeSelectionModel extends DefaultTreeSelectionModel {

private static final long serialVersionUID = -4270031800448415780L;

@Override

public void addSelectionPath(TreePath path) {

// Don't do overriding logic here because addSelectionPaths is ultimately called.

super.addSelectionPath(path);

}

@Override

public void addSelectionPaths(TreePath[] paths) {

if(paths != null) {

for(TreePath path : paths) {

TreePath[] toAdd = new TreePath[1];

toAdd[0] = path;

if (isPathSelected(path)) {

// If path has been previously selected REMOVE THE SELECTION.

super.removeSelectionPaths(toAdd);

} else {

// Else we really want to add the selection...

super.addSelectionPaths(toAdd);

}

}

}

}

HTH.
