JTree with Checkbox Nodes

Hi experts,

 I want to develop a Jtree which is having checkbox to every node and label. When user selects a child node then the parent nodes checkbox should also be selected partially.

 This tree should look like the tree we see many times in windows based applications.

 I wonder how can I do this?.. Please help me in this..

Thanks and Regards,
Lamdor Grauk.
