Refresh JTrees

Hi guys,

I am currently working a project which required me to implement three different hierarchy structure and use combobox to choose between them. I am able to construct three trees and able to display individual correctly. But I have difficulty to refresh the hierachy tree by choose another combobox choice. I would be appreciated if some one can give me a simple examples to show how do I do it.

i.e. I had three combobox color, sport and food. also three corresponding hierachy, at each time only one hierarchy can be displayed by choosing one of the combobox.

Thanks very much
