- Where the interface allows the user to select parts of the hierarchy by clicking the selection boxes. Selecting a node selects all of it's children. Expanding a node and selecting some of it's children cuases the selection icon for the node to indicate that is partially selected. So I would sketch the UI like this:

- And I stopped writing code there because it's clearly going to get a lot more complex pretty quickly and it's time to solicit input. The rest of the idea for the UI is that when a user selects a variable by highlighting (single clicking on) the name in the data set tree the appropriate sub-setting interface appears in the Sub-setting Pane. By navigating the data set tree, clicking the check boxes, and highlighting the selected variables the user can build the data request that they want.

- Basically I can see how to implement custom icons and the like in a JTree but I am stuck on how to get the mouse event behavior I want.
- I imagine that this kind of tree has been implemented in java by someone somewhere.
