# Swing Checkbox Tree

A check box tree package based on John Zukowski's [CheckBox Node Tree
Sample](http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm)
code. 

You can mix and match `DefaultMutableTreeNode` and `CheckBoxNodeData` node
types. It also allows check box nodes as non-leaf nodes.

It uses a `JCheckBox` + `JLabel` in a `JPanel` to differentiate between
clicking on a check box (to check/uncheck a node) versus a label (to select a
node).

* __Simple example:__ [CheckBoxTreeSample](https://github.com/scijava/swing-checkbox-tree/blob/master/src/test/java/org/scijava/swing/checkboxtree/CheckBoxTreeSample.java)
* __Complex example:__ [WatchEventsFrame](https://github.com/imagej/imagej/blob/03a616522d31d9a1777880778cbd11f12f28e3e2/ui/swing/commands/src/main/java/imagej/ui/swing/commands/debug/WatchEventsFrame.java)

The latter example also has code for recursively toggling subtrees in response
to boxes being checked or unchecked (see the `treeNodesChanged` method).
